| serological evidence of infection of tacaribe virus and arboviruses in trinidadian bats. | sera from 39 species of bats collected in trinidad between 1972 and 1974 were tested against some or all of 18 arboviruses in hemagglutination inhibition (hi) and/or suckling mouse neutralization (n) tests. a few sera were hi-positive with mucambo, eastern equine encephalitis (eee), oriboca, restan, manzanilla, guama, bimiti, and catu. no sera were hi-positive with mayaro, caraparu or maguari. many ser inhibited one or more of the group b hemagglutinins: ilheus, st. louis encephalitis (sle), den ... | 1978 | 204207 |
| prevalence of selected zoonotic diseases in vertebrates from haiti, 1972. | vertebrate animals collected in haiti in 1972 were tested for selected zoonotic diseases. no rabies virus or neutralizing (n) antibody was detected in bats (artibeus jamaicensis). however, n antibody against st. louis encephalitis, western equine encephalitis (wee), and eastern equine encephalitis were detected in resident species of birds and wee antibody in bats. no n antibody against venezuelan equine encephalitis was found. the possible introduction by migratory birds and local transmission ... | 1979 | 480524 |
| electrical response of bat retina to spectral stimulation: comparison of four microhiropteran species. | electrical responses of the retinas of 4 species of microchiropteran bats stimulated by spectrally restricted light flashes were found to diverge systematically from the rhodopsin absorption spectrum. the divergence was progressively greater across the 4 species. the results appeared explainable by assuming a second photoreceptor class and photopigment which was present in progressively greater numbers in the retinas of eptesicus fuscus, desmodus rotundus, artibeus jamaicensis and carollia persp ... | 1979 | 488274 |
| venezuelan encephalitis virus infection in neotropical bats. ii. experimental infections. | eighty-nine neotropical bats of five species were inoculated subcutaneously with epizootic or enzootic strains of venezuelan encephalitis (ve) virus. viremia was detected in 92.5% of all bats, but no illness attributable to virus infection was observed. detectable viremias averaged slightly over 4 days in artibeus jamaicensis and a. lituratus, and 2.8 days in phyllostomus discolor, and maximal viremia titers in these three species averaged 6.9, 6.6, and 4.6 log10 smicld50 per ml of blood, respec ... | 1978 | 646022 |
| venezuelan encephalitis virus infection in neotropical bats. iii. experimental studies on virus excretion and non-arthropod transmission. | a total of 80 neotropical bats of five species was inoculated with one of four strains of venezuelan encephalitis (ve) virus. virus was detected in the oropharynges of 56% of bats, and most regularly in artibeus jamaicensis (75%). titers of virus in oropharyngeal secretions were occasionally very high (8.5 log10 smicld50/ml in one a. jamaicensis). only 2 of 123 urine samples from 50 bats and 2 of 86 fecal samples from 46 bats yielded ve virus. no contact or aerosol virus transmission from bat to ... | 1978 | 646023 |
| [histoplasma capsulatum: isolation from bats in cuba]. | a mycologic-serologic study of 169 bats of species artibeus jamaicensis parvipos, brachyphyllanana, eptesicus fuscus dutertreus, tadarida brasiliensis muscula and mormoops blainvillei which were catched in a cave of havana province is presented. histoplasma capsulatum were isolated from the lungs, liver and spleen, in four out of the five species studied. all species were serologically negative. | 1976 | 802802 |
| rabies virus and antibody in bats in grenada and trinidad. | rabies virus was detected by fluorescent-antibody and mouse inoculation tests in the brain of one bat, artibeus jamaicensis, collected at la tante, grenada on 19 june 1974. no rabies virus was found in the brains and/or salivary glands of 411 other grenadian bats of 6 species tested, including 56 a. jamaicensis. rabies neutralizing antibody was detected by the rapid fluorescent focus inhibition test (rffit) in 27 of 353 grenadian bats. positives occurred in each of the 6 species sampled, with 40 ... | 1977 | 864845 |
| isolation of histoplasma capsulatum from tissues of bats captured in the aguas buenas caves, aguas buenos, puerto rico. | of 30 bats belonging to four species, only one species, brachyplylla cavernarum, yielded positive for histoplasma capsulatum. bats were collected at the aguas buenas caves in puerto rico. the other species are: artibeus jamaicensis, monophyllus redmani portoricensis, and erophylla bibombifrons; these resulted negative for the fungus. | 1977 | 865600 |
| intestinal disaccharidases in five species of phyllostomoid bats. | 1. intestinal disaccharidases were studied in nectarivorous (leptonycteris curasoae and glossophaga soricina), frugivorous (artibeus jamaicensis and sturnira lilium), and insectivorous (pteronotus personatus) adult bats. 2. adult bats lacked measurable lactase activity. with the exception of trehalase activity, which was present only in p. personatus, nectar- and fruit-eating bats exhibited higher disaccharidase activities standardized by intestinal nominal area than insect-eating p. personatus. ... | 1992 | 1451428 |
| fine structure of the vomeronasal neuroepithelium of bats: a comparative study. | the vomeronasal neuroepithelium of the vampire bat, desmodus rotundus, and the frugivorous bats, carollia perspicillata and artibeus jamaicensis, was examined at the light-microscopic and ultrastructural levels. the neuroepithelium of these species is basically similar in morphology to that of other mammals. however, hitherto unknown differences were noted in regard to the configuration of the apical poles of cells, in the occurrence of solitary cilia, dislocated sensory cells, brush cells, cell ... | 1982 | 7102243 |
| further characterization of the pituitary-adrenocortical responses to stress in chiroptera. | previous studies on bats from this laboratory have revealed the presence of exceptionally high circulating levels of glucocorticoids in two species of the sub-order megachiroptera. in the present study, the following questions were asked: (1) what effect does the routine handling and examination of captive bats have on the activity of their hypothalamic-pituitary-adrenocortical (hpa) axis?; (2) are the unusually high plasma levels of cortisol and corticosterone found in pteropus hypomelanus asso ... | 1994 | 8057075 |
| histochemical and myosin composition of vampire bat (desmodus rotundus) pectoralis muscle targets a unique locomotory niche. | the vampire bat pectoralis muscle contains at least four fiber types distributed in a nonhomogeneous pattern. one of these fiber types, here termed iie, can be elucidated only by adenosine triphosphatase (atpase) histochemistry combined with reactions against antifast and antislow myosin antibodies. the histochemical and immunohistochemical observations indicate a well-developed specialization of function within specific regions of the muscle. in parallel, analyses of native myosin isoforms and ... | 1993 | 8230235 |
| experimental rabies virus infection in artibeus jamaicensis bats with cvs-24 variants. | an experimental model of rabies was established in the fruit-eating bat species artibeus jamaicensis. the infections caused by cvs-n2c and cvs-b2c, which are both stable variants of cvs-24, were compared after inoculation of adult bats in the right masseter muscle. cvs-n2c produced neurologic signs of rabies with paresis, ataxia, and inability to fly, while cvs-b2c did not produce neurologic signs. bats were sacrificed and the distribution of rabies virus antigen was assessed in tissue sections ... | 2001 | 11704883 |
| first account on the larval biology of a litomosoides filaria, from a bat. | litomosoides filariae are parasites of unrelated groups of hosts, including bats, marsupials, ancient and modern rodents. the four life cycles to-date elucidated, develop in terrestrial mammals and, at least experimentally, in the mite ornithonyssus bacoti. a batch of mites was fed on an infected bat, artibeus jamaicensis captured in costa rica, and 18 days later one infective larva was recovered. its morphology was similar to that of other litomosoides species, with the characteristic long bucc ... | 2002 | 12404814 |
| male dominance, paternity, and relatedness in the jamaican fruit-eating bat (artibeus jamaicensis). | we analysed variation at 14 nuclear microsatellite loci to assess the genetic structure, relatedness, and paternity of polygynous jamaican fruit-eating bats. a total of 84 adults captured in two caves exhibited little genetic differentiation between caves (fst = 0.008). average relatedness among adult females in 10 harem groups was very low (r = 0.014 +/- 0.011), providing no evidence of harem structure. dominant and subordinate males shared paternity in large groups, while dominant and satellit ... | 2003 | 12919478 |
| examination of type material of two species of litomosoides (filarioidea: onchocercidae), parasites from bats; taxonomic consequences. | type material of litomosoides hamletti sandground, 1934 from glossophaga soricina soricina in brazil and l. penai jiménez-quirós & arroyo, 1960 from carollia perspicillata azteca in costa rica, was examined. the morphology of the spicules shows that these species belong to the carinii group. their synonymy with l. guiterasi pérez vigueras, 1934, from artibeus jamaicensis yucatanicus in cuba, does not appear justified because they are distinct in several characters (body length, width of female, ... | 2003 | 14535160 |
| copper-associated hepatopathy in a mexican fruit bat (artibeus jamaicensis) and establishment of a reference range for hepatic copper in bats. | copper toxicity has been described in numerous domestic species. the characteristic lesions include hemoglobinuric nephrosis and piecemeal hepatic necrosis with bile ductular hyperplasia and portal fibrosis. certain species, such as sheep, are prone to toxicity when exposed to copper in feed, whereas an inherent genetic defect of copper storage is present in some breeds of dogs (bedlington terriers, west highland white terriers, doberman pinschers). in nondomestic species, reference ranges have ... | 2004 | 15586580 |
| the intake responses of three species of leaf-nosed neotropical bats. | flower-visiting bats encounter nectars that vary in both sugar composition and concentration. because in the new world, the nectars of bat-pollinated flowers tend to be dominated by hexoses, we predicted that at equicaloric concentrations, bats would ingest higher volumes of hexoses than sucrose-containing nectars. we investigated the intake response of three species of neotropical bats, leptonycteris curasoae, glossophaga soricina and artibeus jamaicensis, to sugar solutions of varying concentr ... | 2008 | 18183405 |
| dengue virus in mexican bats. | individuals belonging to five families, 12 genera, and 19 different species of bats from dengue endemic areas in the gulf and pacific coasts of mexico were examined by elisa, rt-pcr, and for the presence of dengue virus (dv) ns1 protein. nine individuals from four species were seropositive by elisa: three insectivorous, myotis nigricans (four positives/12 examined), pteronotus parnellii (3/19), and natalus stramineus (1/4), and one frugivorous artibeus jamaicensis (1/35) (12.86% seroprevalence i ... | 2008 | 18325131 |
| host-species transferrin receptor 1 orthologs are cellular receptors for nonpathogenic new world clade b arenaviruses. | the ability of a new world (nw) clade b arenavirus to enter cells using human transferrin receptor 1 (tfr1) strictly correlates with its ability to cause hemorrhagic fever. amapari (amav) and tacaribe (tcrv), two nonpathogenic nw clade b arenaviruses that do not use human tfr1, are closely related to the nw arenaviruses that cause hemorrhagic fevers. here we show that pseudotyped viruses bearing the surface glycoprotein (gp) of amav or tcrv can infect cells using the tfr1 orthologs of several ma ... | 2009 | 19343214 |
| habitat fragmentation and haemoparasites in the common fruit bat, artibeus jamaicensis (phyllostomidae) in a tropical lowland forest in panamá. | anthropogenic influence on ecosystems, such as habitat fragmentation, impacts species diversity and interactions. there is growing evidence that degradation of habitats favours disease and hence affects ecosystem health. the prevalence of haemoparasites in the common fruit bat (artibeus jamaicensis) in a tropical lowland forest in panamá was studied. we assessed the relation of haemoparasite to the general condition of the animals and tested for possible association of haemoparasite prevalence t ... | 2009 | 19627629 |
| effects of ingestion by neotropical bats on germination parameters of native free-standing and strangler figs (ficus sp., moraceae). | fruit-eating animals can influence the germination success of seeds through transportation and handling. we experimentally tested the contribution of ingestion by the common fruit-eating bat, artibeus jamaicensis (phyllostomidae, chiroptera), to the percentage and rate of seed germination of figs (ficus, moraceae), which are considered keystone species for many frugivores. we collected fruits from three species of native free-standing figs (subgenus pharmacosycea: f. insipida, f. maxima and f. y ... | 2010 | 20354732 |
| alopecia in bats from tabasco, mexico. | we report alopecic syndrome (hair loss in areas of the body, including chest, abdomen, and back) in four frugivorous bat species (artibeus jamaicensis, artibeus lituratus, sturnira lilium, and sturnira ludovici) within urban and periurban areas of villahermosa, tabasco, méxico, during 2007 and 2008. the overall prevalence of alopecic syndrome was 5.25% (135/2,567 bats). the highest prevalence was found in a. lituratus (5.6%; 62/1,105), followed by a. jamaicensis (5%; 3/1,462). we found a higher ... | 2010 | 20688713 |
| bats (mammalia: chiroptera) in native and reforested areas in rancho alegre, paraná, brazil. | abstract: generally, natural environments have been transformed into small forest remnants, with the consequent habitat loss and species extinction. the north paraná state is not an exception, since only 2 to 4% of the original ecosystem occurs in small fragments of stational semidecidual forest. we studied the species richness and abundance of bats in two forest fragments from the fazenda congonhas, in rancho alegre city, parana state, brazil. four samplings were undertaken in a legally protect ... | 2010 | 21246993 |

| serologic evidence of flavivirus infection in bats in the yucatan peninsula of mexico. | we captured 140 bats of seven species in merida city in the yucatan peninsula of mexico in 2010. serum was collected from each bat and assayed by plaque reduction neutralization test (prnt) using six flaviviruses: west nile virus, st. louis encephalitis virus, and dengue viruses 1-4. flavivirus-specific antibodies were detected in 26 bats (19%). the antibody-positive bats belonged to three species: the pallas's long-tongued bat (glossophaga soricina), jamaican fruit bat (artibeus jamaicensis), a ... | 0 | 23778622 |
| experimental inoculation of artibeus jamaicensis bats with dengue virus serotypes 1 or 4 showed no evidence of sustained replication. | dengue is the most important mosquito-borne viral disease to humans. bats are potential reservoirs for flaviviruses, including dengue virus (denv). in this work, artibeus jamaicensis bats were inoculated with two serotypes of denv using different routes. for experimental inoculations (ei) 1 and 2, bats were inoculated subcutaneously or intraperitoneally with denv-4; for ei-3 bats were inoculated intraperitoneally with denv-1. mock inoculated bats were kept as controls. in ei-4, bats were bitten ... | 2014 | 25311698 |
| transcriptome sequencing and annotation for the jamaican fruit bat (artibeus jamaicensis). | the jamaican fruit bat (artibeus jamaicensis) is one of the most common bats in the tropical americas. it is thought to be a potential reservoir host of tacaribe virus, an arenavirus closely related to the south american hemorrhagic fever viruses. we performed transcriptome sequencing and annotation from lung, kidney and spleen tissues using 454 and illumina platforms to develop this species as an animal model. more than 100,000 contigs were assembled, with 25,000 genes that were functionally an ... | 2012 | 23166587 |
| dengue virus in bats from southeastern mexico. | to identify the relationship between landscape use and dengue virus (denv) occurrence in bats, we investigated the presence of denv from anthropogenically changed and unaltered landscapes in two biosphere reserves: calakmul (campeche) and montes azules (chiapas) in southern mexico. spleen samples of 146 bats, belonging to 16 species, were tested for four denv serotypes with standard reverse transcriptase polymerase chain reaction (rt-pcr) protocols. six bats (4.1%) tested positive for denv-2: fo ... | 2014 | 24752688 |
| neotropical primary bat cell lines show restricted dengue virus replication. | dengue is the most widespread arboviral disease affecting humans. bats are recognized carriers of emerging viral zoonoses and have been proposed as dengue reservoirs, since rna/ns1 and/or antiviral antibodies have been detected. yet, experimental inoculation of artibeus bats failed to show virus replication. this conflicting results prevent drawing further conclusions of whether bats sustain dengue infection. to test bat cellular permissivity to dengue infection, we established primary bat embry ... | 2017 | 28131369 |
| tacaribe virus causes fatal infection of an ostensible reservoir host, the jamaican fruit bat. | tacaribe virus (tcrv) was first isolated from 11 artibeus species bats captured in trinidad in the 1950s during a rabies virus surveillance program. despite significant effort, no evidence of infection of other mammals, mostly rodents, was found, suggesting that no other vertebrates harbored tcrv. for this reason, it was hypothesized that tcrv was naturally hosted by artibeus bats. this is in stark contrast to other arenaviruses with known hosts, all of which are rodents. to examine this hypothe ... | 2012 | 22379103 |
| ecology of bats, their ectoparasites, and associated pathogens on saint kitts island. | ectoparasites of bats and bat-associated pathogens are poorly studied in the lesser antilles islands. we report on an 11-mo field study on saint kitts island of bat populations, their associated ectoparasites, and pathogens. we report on five ectoparasite species, including four streblidae (diptera) and a spinturnicidae (acari). several genotypes of unnamed bartonella were isolated from bats and ectoparasites. microfilaria of an undetermined litomosoides spp. were detected in blood from artibeus ... | 2016 | 27282816 |
| landscape ecology of trypanosoma cruzi in the southern yucatan peninsula. | landscape interactions of trypanosoma cruzi (tc) with triatoma dimidiata (td) depend on the presence and relative abundance of mammal hosts. this study analyzed a landscape adjacent to the calakmul biosphere reserve, composed of conserved areas, crop and farming areas, and the human community of zoh laguna with reported chagas disease cases. sylvatic mammals of the chiroptera, rodentia, and marsupialia orders were captured, and livestock and pets were sampled along with t. dimidiata in all habit ... | 2015 | 26219998 |
| high local diversity of trypanosoma in a common bat species, and implications for the biogeography and taxonomy of the t. cruzi clade. | the trypanosoma cruzi clade is a group of parasites that comprises t. cruzi sensu lato and its closest relatives. although several species have been confirmed phylogenetically to belong to this clade, it is uncertain how many more species can be expected to belong into this group. here, we present the results of a survey of trypanosome parasites of the bat artibeus jamaicensis from the panamá canal zone, an important seed disperser. using a genealogical species delimitation approach, the poisson ... | 2014 | 25268381 |
| exploring population genetic structure in three species of lesser antillean bats. | we explore population genetic structure in phyllostomid bats (ardops nichollsi, brachyphylla cavernarum and artibeus jamaicensis) from the northern lesser antilles by investigating the degree to which island populations are genetically differentiated. our hypothesis, that the island populations are genetically distinct because of a combination of founding events, limited migration and genetic drift exacerbated by catastrophe-induced fluctuations in population size, is derived from a priori hypot ... | 2004 | 15315670 |
| calcification of the lower respiratory tract in relation to flight development in jamaican fruit bats (phyllostomidae, artibeus jamaicensis). | the production of echolocation calls in bats along with forces produced by contraction of thoracic musculature used in flight presumably puts relatively high mechanical loads on the lower respiratory tract (lrt). thus, there are likely adaptations to prevent collapse or distortion of the bronchial tree and trachea during flight in echolocating bats. by clearing and staining (alcian blue and alizarin red) lrts removed from nonvolant neonates, semivolant juveniles, volant subadults, and adult jama ... | 2017 | 28033680 |
| dynamic duos? jamaican fruit bats (artibeus jamaicensis) do not show prosocial behavior in a release paradigm. | once thought to be uniquely human, prosocial behavior has been observed in a number of species, including vampire bats that engage in costly food-sharing. another social chiropteran, jamaican fruit bats (artibeus jamaicensis), have been observed to engage in cooperative mate guarding, and thus might be expected to display prosocial behavior as well. however, frugivory and hematophagy diets may impose different selection pressures on prosocial preferences, given that prosocial preferences may dep ... | 2016 | 27879623 |
| development and characterization of fourteen novel microsatellite markers for the chestnut short-tailed fruit bat (carollia castanea), and cross-amplification to related species. | rapid anthropogenic land use change threatens the primary habitat of the chestnut short-tailed bat (carollia castanea) throughout much of its range. information on population genetic structure can inform management strategies for this widespread frugivorous bat, and effective protection of c. castanea will also benefit the more than 20 mutualistic plant species of which this bat is the primary seed disperser. to facilitate understanding of population genetic structure in this species, fourteen n ... | 2016 | 27688969 |
| environment and host species shape the skin microbiome of captive neotropical bats. | a wide range of microorganisms inhabit animal skin. this microbial community (microbiome) plays an important role in host defense against pathogens and disease. bats (chiroptera: mammalia) are an ecologically and evolutionarily diversified group with a relatively unexplored skin microbiome. the bat skin microbiome could play a role in disease resistance, for example, to white nose syndrome (wns), an infection which has been devastating north american bat populations. however, fundamental knowled ... | 2016 | 27688962 |
| richness, infestation and specificity of spinturnicid mites (acari: spinturnicidae) on bats in southern oaxaca, mexico. | studies of mites on bats in the mexican state oaxaca are scarce. our objective was therefore to evaluate the richness, infestation, and specificity of spinturnicid mites on bats in southern oaxaca, mexico. bats were monthly captured from april 2010 to february 2011, in four sites using four mist-nets; also, we visited natural (crevices) and artificial roosts (tunnel). of each bat we account the number of spinturnicid mites, considering the area of the body where they were collected. mites were p ... | 2016 | 27431824 |
| characterization of the myoepithelial cells in the major salivary glands of the fruit bat artibeus jamaicensis. | bats constitute one of the most numerous mammalian species. bats have a wide range of dietary habits and include carnivorous, haematophagous, insectivorous, frugivorous and nectivorous species. the salivary glands of these species have been of particular research interest due to their structural variability among chiropterans with different types of diets. myoepithelial cells (mecs), which support and facilitate the expulsion of saliva from the secretory portions of salivary glands, are very imp ... | 2016 | 27168421 |
| replication and shedding of mers-cov in jamaican fruit bats (artibeus jamaicensis). | the emergence of middle east respiratory syndrome coronavirus (mers-cov) highlights the zoonotic potential of betacoronaviruses. investigations into the origin of mers-cov have focused on two potential reservoirs: bats and camels. here, we investigated the role of bats as a potential reservoir for mers-cov. in vitro, the mers-cov spike glycoprotein interacted with jamaican fruit bat (artibeus jamaicensis) dipeptidyl peptidase 4 (dpp4) receptor and mers-cov replicated efficiently in jamaican frui ... | 2016 | 26899616 |
| in vitro capacitation and acrosome reaction in sperm of the phyllostomid bat artibeus jamaicensis. | sperm capacitation occurs during the passage of sperm through the female reproductive tract. once the sperm binds to the pellucid zone, the acrosome reaction to enable penetration of the oocyte is completed. in this study, sperm of artibeus jamaicensis bat was used to evaluate both capacitation status and the acrosome reaction under in vitro conditions, incubating sperm at 32 and 37°c with and without progesterone. sperm was incubated at different times to assess sperm cells' functionality in te ... | 2016 | 26744028 |
| social grooming in bats: are vampire bats exceptional? | evidence for long-term cooperative relationships comes from several social birds and mammals. vampire bats demonstrate cooperative social bonds, and like primates, they maintain these bonds through social grooming. it is unclear, however, to what extent vampires are special among bats in this regard. we compared social grooming rates of common vampire bats desmodus rotundus and four other group-living bats, artibeus jamaicensis, carollia perspicillata, eidolon helvum and rousettus aegyptiacus, u ... | 2015 | 26445502 |
| phyllostomid bat microbiome composition is associated to host phylogeny and feeding strategies. | the members of the phyllostomidae, the new-world leaf-nosed family of bats, show a remarkable evolutionary diversification of dietary strategies including insectivory, as the ancestral trait, followed by appearance of carnivory and plant-based diets such as nectarivory and frugivory. here we explore the microbiome composition of different feeding specialists: insectivore macrotus waterhousii, sanguivore desmodus rotundus, nectarivores leptonycteris yerbabuenae and glossophaga soricina, and frugi ... | 2015 | 26042099 |
| postnatal ontogeny of the cochlea and flight ability in jamaican fruit bats (phyllostomidae) with implications for the evolution of echolocation. | recent evidence has shown that the developmental emergence of echolocation calls in young bats follow an independent developmental pathway from other vocalizations and that adult-like echolocation call structure significantly precedes flight ability. these data in combination with new insights into the echolocation ability of some shrews suggest that the evolution of echolocation in bats may involve inheritance of a primitive sonar system that was modified to its current state, rather than the a ... | 2015 | 25831957 |
| neotropical bats from costa rica harbour diverse coronaviruses. | bats are hosts of diverse coronaviruses (covs) known to potentially cross the host-species barrier. for analysing coronavirus diversity in a bat species-rich country, a total of 421 anal swabs/faecal samples from costa rican bats were screened for cov rna-dependent rna polymerase (rdrp) gene sequences by a pancoronavirus pcr. six families, 24 genera and 41 species of bats were analysed. the detection rate for cov was 1%. individuals (n = 4) from four different species of frugivorous (artibeus ja ... | 2015 | 25653111 |
| bartonella spp. in a puerto rican bat community. | we captured and sampled 68 bats of six species from a shared roosting site in puerto rico in april 2012. bats were screened for bartonella spp. by culture and confirmed by pcr and sequencing for the glta gene. bartonella cultures were obtained from blood specimens of 9/51 (18%) individuals from three species (artibeus jamaicensis, brachyphylla cavernarum, and monophyllus redmani). phylogenetic analysis of the glta sequences showed that m. redmani was infected with multiple, diverse bartonella st ... | 2015 | 25380361 |
| membrane muscle function in the compliant wings of bats. | unlike flapping birds and insects, bats possess membrane wings that are more similar to many gliding mammals. the vast majority of the wing is composed of a thin compliant skin membrane stretched between the limbs, hand, and body. membrane wings are of particular interest because they may offer many advantages to micro air vehicles. one critical feature of membrane wings is that they camber passively in response to aerodynamic load, potentially allowing for simplified wing control. however, for ... | 2014 | 24855069 |
| ontogeny of the larynx and flight ability in jamaican fruit bats (phyllostomidae) with considerations for the evolution of echolocation. | echolocating bats have adaptations of the larynx such as hypertrophied intrinsic musculature and calcified or ossified cartilages to support sonar emission. we examined growth and development of the larynx relative to developing flight ability in jamaican fruit bats to assess how changes in sonar production are coordinated with the onset of flight during ontogeny as a window for understanding the evolutionary relationships between these systems. in addition, we compare the extent of laryngeal ca ... | 2014 | 24778087 |
| characterization of gametes in two phyllostomid bat species: artibeus jamaicensis and sturnira lilium. | morphology of gametes is used to understand the physiological processes in reproduction among domestic and wild animals. these gametes are used in assisted reproductive technology (art) and conservation programs. in the case of artibeus jamaicensis and sturnira lilium, few studies have been conducted related to these issues. the aim of this study was to describe the structure of spermatozoa, semen characteristics and also the morphology and quality of cumulus oocyte complexes (coc) of a. jamaice ... | 2014 | 24576400 |
| identification of cortical germ cells in adult ovaries from three phyllostomid bats: artibeus jamaicensis, glossophaga soricina and sturnira lilium. | it is generally considered that, in mammals, the ovary is endowed with a finite number of oocytes at the time of birth. however, studies concerning rodents, lemurs and humans suggest the existence of stem cells from the germline that may be involved in germ-cell renewal, maintaining postnatal follicle development. this type of work on wild species is scarce; therefore the objective of this study was to determine ovarian morphology and the presence of progenitor cells from the germline of three s ... | 2013 | 22953782 |
| dna barcoding and genetic diversity of phyllostomid bats from the yucatan peninsula with comparisons to central america. | the mitochondrial cytochrome c oxidase subunit i gene is the standard dna barcoding region used for species identification and discovery. we examined the variation of coi (454 bp) to discriminate 20 species of bats in the family phyllostomidae that are found in the yucatan peninsula of southeastern mexico and northern guatemala and compared them genetically to other samples from central america. the majority of these species had low intraspecific variation (mean = 0.75%), but some taxa had intra ... | 2012 | 22372841 |
| two novel parvoviruses in frugivorous new and old world bats. | bats, a globally distributed group of mammals with high ecological importance, are increasingly recognized as natural reservoir hosts for viral agents of significance to human and animal health. in the present study, we evaluated pools of blood samples obtained from two phylogenetically distant bat families, in particular from flying foxes (pteropodidae), eidolon helvum in west africa, and from two species of new world leaf-nosed fruit bats (phyllostomidae), artibeus jamaicensis and artibeus lit ... | 2011 | 22216187 |
| sound-evoked oscillation and paradoxical latency shift in the inferior colliculus neurons of the big fruit-eating bat, artibeus jamaicensis. | frequency tuning, temporal response pattern and latency properties of inferior colliculus neurons were investigated in the big fruit-eating bat, artibeus jamaicensis. neurons having best frequencies between 48-72 khz and between 24-32 khz are overrepresented. the inferior colliculus neurons had either phasic (consisting in only one response cycle at all stimulus intensities) or long-lasting oscillatory responses (consisting of multiple response cycles). seventeen percent of neurons displayed par ... | 2011 | 21912875 |
| drinking and flying: does alcohol consumption affect the flight and echolocation performance of phyllostomid bats? | in the wild, frugivorous and nectarivorous bats often eat fermenting fruits and nectar, and thus may consume levels of ethanol that could induce inebriation. to understand if consumption of ethanol by bats alters their access to food and general survival requires examination of behavioural responses to its ingestion, as well as assessment of interspecific variation in those responses. we predicted that bats fed ethanol would show impaired flight and echolocation behaviour compared to bats fed co ... | 2010 | 20126552 |
| intense echolocation calls from two 'whispering' bats, artibeus jamaicensis and macrophyllum macrophyllum (phyllostomidae). | bats use echolocation to exploit a variety of habitats and food types. much research has documented how frequency-time features of echolocation calls are adapted to acoustic constraints imposed by habitat and prey but emitted sound intensities have received little attention. bats from the family of phyllostomidae have been categorised as low intensity (whispering) gleaners, assumed to emit echolocation calls with low source levels (approximately 70 db spl measured 10 cm from the bat's mouth). we ... | 2009 | 19088206 |
| food niche overlap among neotropical frugivorous bats in costa rica. | food habits of 15 species of frugivorous bats were studied at la selva biological station, costa rica. eight hundred and fifty-four (854) fecal samples and 169 samples from fruit parts and seeds discarded by bats beneath feeding roosts were analyzed. during eight months of study, 47 fruit species consumed by bats were identified. five plant genera (cecropia, ficus, piper solanum, and vismia) constituted 85% of all plants found in fecal samples. feeding niche breadth differed significantly among ... | 2007 | 18457139 |
| techniques for modeling muscle-induced forces in finite element models of skeletal structures. | this work introduces two mechanics-based approaches to modeling muscle forces exerted on curvilinear bone structures and compares the results with two traditional ad hoc methods of muscle loading. these new models use a combination of tensile, tangential, and normal traction loads to account for muscle fibers wrapped around curved bone surfaces. a computer program was written to interface with a commercial finite element analysis tool to automatically apply traction loads to surface faces of ele ... | 2007 | 17721980 |
| effect of fasting on carbohydrate metabolism in frugivorous bats (artibeus lituratus and artibeus jamaicensis). | the compensatory changes of carbohydrate metabolism induced by fasting were investigated in frugivorous bats, artibeus lituratus and artibeus jamaicensis. for this purpose, plasma levels of glucose and lactate, liver and muscle glycogen content, rates of liver gluconeogenesis and the activity of related enzymes were determined in male bats. after a decrease during the first 48 h of fasting, plasma glucose levels remained constant until the end of the experimental period. plasma lactate levels, e ... | 2006 | 16455278 |
| threshold minima and maxima in the behavioral audiograms of the bats artibeus jamaicensis and eptesicus fuscus are not produced by cochlear mechanics. | behavioral audiograms of artibeus jamaicensis and eptesicus fuscus are characterized by two threshold minima separated by a threshold maximum at 40 khz, for a. jamaicensis, and 45 khz, for e. fuscus [koay, g., heffner, h.e., heffner r.s., 1997. audiogram of the big brown bat (eptesicus fuscus). hear. res. 105, 202-210; heffner, r.s., koay, g., heffner h.e., 2003. hearing in american leaf-nosed bats. iii: artibeus jamaicensis. hear. res. 184, 113-122.]. to investigate whether these characteristic ... | 2006 | 16434158 |
| reproduction elevates the corticosterone stress response in common fruit bats. | changes in reproductive state or the environment may affect the sensitivity of the hypothalamic-pituitary-andrenal (hpa) axis. however, little is known about the dynamics of the resulting corticosteroid stress response, in particular in tropical mammals. in this study, we address the modulation of corticosterone release in response to different reproductive conditions and seasonality in 326 free-living common fruit-eating bats (artibeus jamaicensis) on barro colorado island in panama during dry ... | 2006 | 16273409 |
| finite-element analysis of biting behavior and bone stress in the facial skeletons of bats. | the wide range of dietary niches filled by modern mammals is reflected in morphological diversity of the feeding apparatus. despite volumes of data on the biomechanics of feeding, the extent to which the shape of mammal skulls reflects stresses generated by feeding is still unknown. in addition to the feeding apparatus, the skull accommodates the structural needs of the sensory systems and brain. we turned to bats as a model system for separating optimization for masticatory loads from optimizat ... | 2005 | 15747350 |

| hearing in american leaf-nosed bats. iii: artibeus jamaicensis. | we determined the audiogram of the jamaican fruit-eating bat (phyllostomidae: artibeus jamaicensis), a relatively large (40-50 g) species that, like other phyllostomids, uses low-intensity echolocation calls. a conditioned suppression/avoidance procedure with a fruit juice reward was used for testing. at 60 db spl the hearing range of a. jamaicensis extends from 2.8 to 131 khz, with an average best sensitivity of 8.5 db spl at 16 khz. although their echolocation calls are low-intensity, the abso ... | 2003 | 14553909 |
| observations on serum 25-hydroxyvitamin d and calcium concentrations from wild-caught and captive neotropical bats, artibeus jamaicensis. | most bats of the suborder microchiroptera are nocturnal, actively avoid sunlight, and eat mineral-poor diets. in those bats previously studied with respect to mineral metabolism, extensive bone remodeling occurs, and it has been suggested that calcium has been an important constraint on reproduction. there have been no previous studies of vitamin d or its metabolites in microchiropteran bats with respect to calcium metabolism. reported is the utilization of current advances for the determination ... | 2001 | 11316428 |
| sound localization in a new-world frugivorous bat, artibeus jamaicensis: acuity, use of binaural cues, and relationship to vision. | passive sound-localization acuity and its relationship to vision were determined for the echolocating jamaican fruit bat (artibeus jamaicensis). a conditioned avoidance procedure was used in which the animals drank fruit juice from a spout in the presence of sounds from their right, but suppressed their behavior, breaking contact with the spout, whenever a sound came from their left, thereby avoiding a mild shock. the mean minimum audible angle for three bats for a 100-ms noise burst was 10 degr ... | 2001 | 11206172 |
| the phylogenetic position of the talpidae within eutheria based on analysis of complete mitochondrial sequences. | the complete mitochondrial (mt) genome of the mole talpa europaea was sequenced and included in phylogenetic analyses together with another lipotyphlan (insectivore) species, the hedgehog erinaceus europaeus, and 22 other eutherian species plus three outgroup taxa (two marsupials and a monotreme). the phylogenetic analyses reconstructed a sister group relationship between the mole and fruit bat artibeus jamaicensis (order chiroptera). the talpa/artibeus clade constitutes a sister clade of the ce ... | 2000 | 10666706 |
| comparative analysis of the digestive efficiency and nitrogen and energy requirements of the phyllostomid fruit-bat (artibeus jamaicensis) and the pteropodid fruit-bat (rousettus aegyptiacus). | nitrogen (n) and energy (e) requirements of the phyllostomid fruit bat, artibeus jamaicensis, and the pteropodid fruit bat rousettus aegyptiacus, were measured in adults that were fed on four experimental diets. mean daily food intake by a. jamaicensis and r. aegyptiacus ranged from 1.1-1.6 times body mass and 0.8-1.0 times body mass, respectively. dry matter digestibility and metabolizable e coefficient were high (81.1% and 82.4%, respectively) for a. jamaicensis and (77.5% and 78.0%, respectiv ... | 1999 | 10227185 |
| complete mitochondrial genome of a neotropical fruit bat, artibeus jamaicensis, and a new hypothesis of the relationships of bats to other eutherian mammals. | the complete mitochondrial genome was obtained from a microchiropteran bat, artibeus jamaicensis. the presumptive amino acid sequence for the protein-coding genes was compared with predicted amino acid sequences from several representatives of other mammalian orders. data were analyzed using maximum parsimony, maximum likelihood, and neighbor joining. all analyses placed bats as the sister group of carnivores, perissodactyls, artiodactyls, and cetaceans (e.g., 100% bootstrap value with both maxi ... | 1998 | 9847413 |
| rapidly evolving repetitive dnas in a conservative genome: a test of factors that affect chromosomal evolution. | the hypothesis that tandemly repeated dna sequences may facilitate chromosomal rearrangements was tested by comparing a conservatively evolving karyotype of a bat species (macrotus waterhousii) with data published for a rapidly evolving karyotype of an equid species (equus zebra). empirical data generated from the phylogenetic screening of rapidly evolving repetitive dnas from approximately 0.1% of the m. waterhousii genome showed only one sequence that was repetitive in m. waterhousii but low i ... | 1994 | 7981939 |
| histochemistry of flight muscles in the jamaican fruit bat, artibeus jamaicensis: implications for motor control. | two fast-twitch fiber types are histochemically identified in the primary flight muscles of artibeus jamaicensis. these are classified as type iia and iib according to an acid-preincubation staining protocol for myosin atpase. all fibers in the bat flight muscles exhibit relatively intense staining properties for nadh-tr, suggesting a high oxidative capacity. the glycolytic potential of all fibers is rather low, as assessed by stains for alpha-gpd. this two-type histochemical profile appears to ... | 1988 | 2458476 |
| mitochondrial dna polymorphism in three antillean island populations of the fruit bat, artibeus jamaicensis. | the neotropical fruit bat, artibeus jamaicensis, occurs throughout latin america and on many islands in the caribbean. populations from jamaica (in the greater antilles) to barbados (in the lesser antilles) have been classified as a subspecies (a.j. jamaicensis) separate from that on the lesser antillean island of st. vincent (a.j. schwartzi). mitochondrial dna (mtdna) was isolated from 54 individuals collected on these islands, analyzed by digestion with restriction endonucleases, and the restr ... | 1988 | 2833678 |
| retinofugal projections of the big brown bat, eptesicus fuscus and the neotropical fruit bat, artibeus jamaicensis. | retinal connections were studied in eptesicus fuscus and artibeus jamaicensis using anterograde axonal degeneration and autoradiographic techniques following unilateral enucleations and uniocular injections of radioactive amino acids. although each retina projected bilaterally to the brainstem, the number of silver grains in the emulsion of autoradiographs indicated that nearly all fibers in the optic nerve entered the contralateral optic tract. ipsilaterally, a major portion of the projection e ... | 1985 | 2983524 |
| renal function in the neotropical bat, artibeus jamaicensis. | 1. when feeding on figs (ficus insipida), the bat artibeus jamaicensis increases dietary sodium density while decreasing potassium density by primarily extracting and ingesting pulp juices rather than other parts of the fruit. 2. based on urine osmotic pressure, these bats are uniformly dehydrated when they leave day roosts and become rapidly rehydrated (0.5-1 hr) after initiation of feeding. 3. after 2000 hr, and throughout the night there is no difference in urine concentration of free-flying ... | 1983 | 6131764 |
| efficiency of food utilization by fruit bats. | neotropical fruit bats consume figs (ficus spp.) and other fruit in small bites which they suck dry and drop as pellets. the swallowed juice transits the short digestive system in 0.5 h or less. the efficiency of this unusual mode of feeding was determined by comparing the nutritional content of pellets, feces and urine of captive artibeus jamaicensis to that of the wild figs (ficus insipida) they had been fed. the bats extracted 57% of the wet weight and 37% of the dry weight of the fruit. the ... | 1980 | 28309539 |
| olfaction in artibeus jamaicensis and myotis lucifugus in the context of vision and echolocation. | calculated retinal and olfactory surface areas of the mexican fruit-bat artibeus jamaicensis and the little brown bat myotis lucifugus, when compared with known eye sizes and echolocation capabilities, suggest that vision and olfaction both may diminish in relative importance as facility for orientation by echolocation increases. | 1975 | 1140332 |
| artibeus jamaicensis: delayed embryonic development in a neotropical bat. | in panama the phyllostomid bat artibeus jamaicensis is seasonally polyestrous, and young are born in march or april and july or august. blastocysts conceived after the second birth implant in the uterus but are dormant from september to mid-november, when normal development again resumes. | 1971 | 5538936 |

| natural exposure of bats in grenada to rabies virus. | introduction: grenada is a rabies endemic country, where terrestrial rabies is maintained in the small indian mongoose (herpestes auropunctatus). the role of bats in the epidemiology of rabies in grenada is unknown. a 1974 report described one rabies virus positive jamaican fruit bat (artibeus jamaicensis), and a high seroprevalence in this species. in the current study, the natural exposure to rabies virus in grenadian bats was re-evaluated. it is postulated that bats serve as a natural rabies ... | 2017 | 28804595 |
| comparative landscape genetics of two frugivorous bats in a biological corridor undergoing agricultural intensification. | agricultural intensification in tropical landscapes poses a new threat to the ability of biological corridors to maintain functional connectivity for native species. we use a landscape genetics approach to evaluate impacts of expanding pineapple plantations on two widespread and abundant frugivorous bats in a biological corridor in costa rica. we hypothesize that the larger, more mobile artibeus jamaicensis will be less impacted by pineapple than the smaller carollia castanea. in 2012 and 2013, ... | 2017 | 28672105 |
| sources of assimilated protein in five species of new world frugivorous bats. | fruits are n-poor items and their availability in the tropics varies throughout the year. field and experimental studies debate whether frugivorous bats have to switch to n-rich sources of food during part of the year or if they are able to subsist on a fruit-only diet. different strategies to meet their n requirements may influence the way in which frugivorous bats partition food resources allowing the coexistence of numerous species in tropical communities. we examined the extent to which five ... | 2002 | 28466224 |
| permeability of hair to cadmium, copper and lead in five species of terrestrial mammals and implications in biomonitoring. | the capacity of mammal hair to absorb toxic metals and its utility in biomonitoring has been broadly studied. though these metal-binding properties has generally been attributed to the sulphur contained in cysteine, an amino acid that forms part of keratin, there are not many experimental studies that analyze the role of sulphur in the external deposition of potentially toxic metallic elements in order to better understand the potential of hair in biomonitoring and generate better tools for diff ... | 2017 | 29151127 |
| transcriptomic signatures of tacaribe virus-infected jamaican fruit bats. | tacaribe virus (tcrv) is a mammalian arenavirus that was first isolated from artibeus bats in the 1950s. subsequent experimental infection of jamaican fruit bats (artibeus jamaicensis) caused a disease similar to that of naturally infected bats. although substantial attention has focused on bats as reservoir hosts of viruses that cause human disease, little is known about the interactions between bats and their pathogens. we performed a transcriptome-wide study to illuminate the response of jama ... | 2017 | 28959737 |
| serological evidence of arenavirus circulation among fruit bats in trinidad. | tacaribe virus (tcrv) was isolated in the 1950s from artibeus bats captured on the island of trinidad. the initial characterization of tcrv suggested that artibeus bats were natural reservoir hosts. however, nearly 60 years later experimental infections of jamaican fruit bats (artibeus jamaicensis) resulted in fatal disease or clearance, suggesting artibeus bats may not be a reservoir host. to further evaluate the tcrv reservoir host status of artibeus bats, we captured bats of six species in tr ... | 2017 | 28953976 |
| serological evidence of widespread exposure of grenada fruit bats to chikungunya virus. | antibody detection against selected potentially zoonotic vector-borne alphaviruses and flaviviruses was conducted on sera from bats from all six parishes in grenada, west indies. sera were tested for (i) antibodies to flaviviruses west nile virus, st. louis encephalitis virus, ilhéus virus, bussuquara virus (bsqv), rio bravo virus and all four serotypes of dengue virus (denv) by plaque reduction neutralization test (prnt); (ii) antibodies to alphaviruses western equine encephalitis virus, venezu ... | 2018 | 29575672 |
| experimental zika virus infection of jamaican fruit bats (artibeus jamaicensis) and possible entry of virus into brain via activated microglial cells. | the emergence of zika virus (zikv) in the new world has led to more than 200,000 human infections. perinatal infection can cause severe neurological complications, including fetal and neonatal microcephaly, and in adults there is an association with guillain-barré syndrome (gbs). zikv is transmitted to humans by aedes sp. mosquitoes, yet little is known about its enzootic cycle in which transmission is thought to occur between arboreal aedes sp. mosquitos and non-human primates. in the 1950s and ... | 2019 | 30716104 |
| molecular adaptation and convergent evolution of frugivory in old world and neotropical fruit bats. | although cases of independent adaptation to the same dietary niche have been documented in mammalian ecology, the molecular correlates of such shifts are seldom known. here, we used genomewide analyses of molecular evolution to examine two lineages of bats that, from an insectivorous ancestor, have both independently evolved obligate frugivory: the old world family pteropodidae and the neotropical subfamily stenodermatinae. new genome assemblies from two neotropical fruit bats (artibeus jamaicen ... | 2020 | 32633855 |
| surgical orchiectomy in fruit bats-description of two techniques in the ruwenzori long-haired fruit bat (rousettus lanosus) and the jamaican fruit-eating bat (artibeus jamaicensis). | contraception is needed to prevent overpopulation and inbreeding in highly fecund captive bat colonies. reports on surgical contraception in bats are limited. the objective of this study was to describe surgical castration techniques in a megachiropteran and a microchiropteran fruit bat species. open orchiectomy by transfixing ligation of the spermatic cord was performed in 14 ruwenzori long-haired fruit bats (rousettus lanosus) (rl-lig), and orchiectomy with radiosurgery alone was performed in ... | 2020 | 32549558 |
| differential cellular proliferation underlies heterochronic generation of cranial diversity in phyllostomid bats. | skull diversity in the neotropical leaf-nosed bats (phyllostomidae) evolved through a heterochronic process called peramorphosis, with underlying causes varying by subfamily. the nectar-eating (subfamily glossophaginae) and blood-eating (subfamily desmondontinae) groups originate from insect-eating ancestors and generate their uniquely shaped faces and skulls by extending the ancestral ontogenetic program, appending new developmental stages and demonstrating peramorphosis by hypermorphosis. howe ... | 2020 | 32514331 |
| genomic consequences of dietary diversification and parallel evolution due to nectarivory in leaf-nosed bats. | the new world leaf-nosed bats (phyllostomids) exhibit a diverse spectrum of feeding habits and innovations in their nutrient acquisition and foraging mechanisms. however, the genomic signatures associated with their distinct diets are unknown. | 2020 | 32510151 |
| reinforcement of the larynx and trachea in echolocating and non-echolocating bats. | the synchronization of flight mechanics with respiration and echolocation call emission by bats, while economizing these behaviors, presumably puts compressive loads on the cartilaginous rings that hold open the respiratory tract. previous work has shown that during postnatal development of artibeus jamaicensis (phyllostomidae), the onset of adult echolocation call emission rate coincides with calcification of the larynx, and the development of flight coincides with tracheal ring calcification. ... | 2020 | 32319086 |
| hematologic values of jamaican fruit bats (artibeus jamaicensis) and the effects of isoflurane anesthesia. | jamaican fruit bats (artibeus jamaicensis) are used as an animal model for several viruses, including middle east respiratory syndrome virus, dengue virus, zika virus, and tacaribe virus. however, despite ongoing studies regarding these pathogens, little is known regarding the bats' normal physiology. in this study, phlebotomy of the propetagial (cephalic) vein was performed to establish baseline hematologic parameters in an apparently healthy, captive population of jamaican fruit bats. furtherm ... | 2020 | 32164795 |
