| ecological factors associated with european bat lyssavirus seroprevalence in spanish bats. | bats have been proposed as major reservoirs for diverse emerging infectious viral diseases, with rabies being the best known in europe. however, studies exploring the ecological interaction between lyssaviruses and their natural hosts are scarce. this study completes our active surveillance work on spanish bat colonies that began in 1992. herein, we analyzed ecological factors that might affect the infection dynamics observed in those colonies. between 2001 and 2011, we collected and tested 2,39 ... | 2013 | 23700480 |
| insights into persistence mechanisms of a zoonotic virus in bat colonies using a multispecies metapopulation model. | rabies is a worldwide zoonosis resulting from lyssavirus infection. in europe, eptesicus serotinus is the most frequently reported bat species infected with lyssavirus, and thus considered to be the reservoir of european bat lyssavirus type 1 (eblv-1). to date, the role of other bat species in eblv-1 epidemiology and persistence remains unknown. here, we built an eblv-1-transmission model based on local observations of a three-cave and four-bat species (myotis capaccinii, myotis myotis, miniopte ... | 2014 | 24755619 |
| cell entry by a novel european filovirus requires host endosomal cysteine proteases and niemann-pick c1. | lloviu virus (llov), a phylogenetically divergent filovirus, is the proposed etiologic agent of die-offs of schreibers's long-fingered bats (miniopterus schreibersii) in western europe. studies of llov remain limited because the infectious agent has not yet been isolated. here, we generated a recombinant vesicular stomatitis virus expressing the llov spike glycoprotein (gp) and used it to show that llov gp resembles other filovirus gp proteins in structure and function. llov gp must be cleaved b ... | 2014 | 25310500 |
| handedness in the echolocating schreiber's long-fingered bat (miniopterus schreibersii). | bats, in terms of variety of species and their absolute numbers, are the most successful mammals on earth. the anatomical and functional peculiarities of microchiroptera are not confined only to the auditory system; the wings (hands) of bats are unique both from an anatomical point of view as from a sensorial one. they are much thinner than those of birds and their bony structure is much more similar to a primate hand than to the forelimb of other mammals of the bat's size; the thumb, is very sm ... | 2010 | 20399840 |
| the role of early development in mammalian limb diversification: a descriptive comparison of early limb development between the natal long-fingered bat (miniopterus natalensis) and the mouse (mus musculus). | comparative embryology expands our understanding of unique limb structures, such as that found in bats. bat forelimb digits 2 to 5 are differentially elongated and joined by webbing, while the hindlimb digits are of similar length in many species. we compare limb development between the mouse and the natal long-fingered bat, miniopterus natalensis, to pinpoint the stage at which their limbs begin to differ. the bat forelimb differs from the mouse at carollia stage (cs) 14 with the appearance of ... | 2009 | 19253395 |
| helminth parasites of natal long-fingered bats, miniopterus natalensis (chiroptera: miniopteridae), south africa. | the helminth community infecting miniopterus natalensis was studied at two localities, the de hoop nature reserve (dhnr) (n = 57), western cape province and pretoria (n = 12), gauteng province, south africa. hosts from the dhnr had formed part of an earlier, unrelated study and were all pregnant females. a single hymenolepidid cestode species, the nematodes molinostrongylus ornatus and litomosa chiropterorum together with nematodes of the subfamily capillariinae were present at both study sites, ... | 2008 | 19040141 |
| pinpointing the vesper bat transposon revolution using the miniopterus natalensis genome. | around 40 million years ago dna transposons began accumulating in an ancestor of bats in the family vespertilionidae. since that time, class ii transposons have been continuously reinvading and accumulating in vespertilionid genomes at a rate that is unprecedented in mammals. miniopterus (miniopteridae), a genus of long-fingered bats that was recently elevated from vespertilionidae, is the sister taxon to the vespertilionids and is often used as an outgroup when studying transposable elements in ... | 2016 | 27489570 |
| distribution and morphology of cholinergic, catecholaminergic and serotonergic neurons in the brain of schreiber's long-fingered bat, miniopterus schreibersii. | the current study describes the nuclear parcellation and neuronal morphology of the cholinergic, catecholaminergic and serotonergic systems within the brain of a representative species of microbat. while these systems have been investigated in detail in the laboratory rat, and examined in several other mammalian species, no chiropterans, to the author's knowledge, have been examined. using immunohistochemical stains for choline-acetyltransferase, tyrosine hydroxylase and serotonin, we were able ... | 2007 | 17560075 |
| a family matter: conclusive resolution of the taxonomic position of the long-fingered bats, miniopterus. | the long-fingered bats (miniopterus sp.) are among the most widely distributed mammals in the world. however, despite recent focus on the systematics of these bats, their taxonomic position has not been resolved. traditionally, they are considered to be sole members of miniopterinae, 1 of 5 subfamilies within the largest family of bats, the vespertilionidae. however, this classification has increasingly been called into question. miniopterines differ extensively from other vespertilionids in num ... | 2007 | 17449895 |
| noradrenergic and cholinergic nerves in the uterus of the japanese long-fingered bat, miniopterus schreibersii fuliginosus, change with reproductive cycle. | the pattern of uterine innervation by noradrenergic (na) and acetylcholinesterase-positive (ache) nerves in different reproductive stages of the adult japanese long-fingered bats were investigated histochemically and immunohistochemically. in the non-pregnant bat, the uterine horn was supplied with abundant na and ache nerves. these two types of nerves were closely associated with the uterine arteries and myometrial smooth muscles. in the pregnant bat, na and ache nerves supplying the uterus did ... | 2002 | 12130815 |
| effects of prolactin and hcg treatment on luteal activity and the conceptus during delayed implantation in schreibers' long-fingered bat (miniopterus schreibersii). | in schreibers' long-fingered bat (miniopterus schreibersii) from south africa, implantation is delayed from may to august during which time the corpus luteum is inactive and plasma progesterone and lh concentrations low. treatment of pregnant long-fingered bats with exogenous prolactin for 10 days in early delayed implantation (may) resulted in changes in luteal ultrastructure that were consistent with increased steroidogenesis, high plasma progesterone concentrations and the initiation of impla ... | 1994 | 8021852 |
| ultrastructural observations of ovulation in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | in the japanese long-fingered bat, miniopterus schreibersii fuliginosus, ovulation occurred spontaneously with the disappearance of the granulosa layer and germinal epithelium at the apex of the stigma which was formed simultaneously with expulsion of the first polar body, and with the subsequent bleeding from the capillary lumina of the theca interna. after ovulation the rupture point was plugged by luteinizing granulosa cells and overgrown by newly regenerated cells of the tunica albuginea and ... | 1981 | 7299746 |
| sperm storage in the reproductive tract of the female japanese long-fingered bat, miniopterus schreibersii fuliginosus. | in the japanese long-fingered bat, miniopterus schreibersii fuliginosus, spermatozoa in contact with the microvilli of non-ciliated cells in folds in the uterotubal junction appeared normal, while spermatozoa remaining in the uterus degenerated and were engulfed by a massive invasion of polymorphonuclear leucocytes. no leucocytes were seen in the uterotubal junction area. it is suggested that the spermatozoa in this area are being stored, probably until ovulation occurs. | 1980 | 7191895 |

| ultrastructural observations of delayed implantation in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | embryonic development in japanese long-fingered bats proceeded very slowly during and after the delayed implantation period (mid-october to mid-december). the primitive amniotic cavity and endoderm were formed before implantation. at the preimplantation stage (before hibernation) the corpus luteum cells appeared active, but became less active at the implantation stage (in hibernation). activity was again apparent at the early placentation stage (after arousal). | 1983 | 6887134 |
| effects of elevated temperatures on the embryonic development and corpus luteum activity in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | gravid female japanese long-fingered bats were kept in captivity without hibernation at elevated temperatures (23-25 degrees c) in winter. the embryonic growth rate was accelerated and consequently parturition was advanced by a period equivalent to that of exclusion from hibernation as compared with that in the wild population. the corpus luteum became active, as indicated by an increase in the 'light' lutein cells in an experimental bat pregnant with a 15-mm embryo, but was less active (more 'd ... | 1984 | 6747953 |
| changes in progesterone concentrations in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | in the japanese long-fingered bat, when compared with the baseline values during non-pregnancy in the autumn, plasma progesterone concentrations were not significantly elevated during the delayed implantation stage that begins before the bats enter hibernation. however, progesterone concentrations were significantly lower during the delayed development stage that occurs during hibernation and rose significantly during the rapid embryogenesis that occurs after arousal from hibernation in the spri ... | 1987 | 3598973 |
| fine structure of the neck of epididymal spermatozoa of schreiber's long-fingered bat (chiroptera: mammalia). | the structure of the spermatozoon of the long-fingered bat (miniopterus schreibersii) was studied using transmission electron microscopy. the neck is characterized by two asymmetrically arranged features that allow the orientation of sections in different planes and therefore aid the interpretation of the structure. there are six segmented columns, two major and four minor, in the anterior 79% of the neck, and it is only posterior to this that the major columns split. one major column is associa ... | 1988 | 3229722 |
| patterns of leydig cell and lh gonadotroph activity, and plasma testosterone concentrations in the seasonally reproducing schreibers' long-fingered bat (miniopterus schreibersii). | spermatogenesis in schreibers' long-fingered bat from approximately 33 degrees s in south africa was seasonal, and occurred in the 3 months (february-april) preceding ovulation. the ultrastructure of the leydig cells indicated a period of increased steroidogenesis at this time, and plasma testosterone concentrations were elevated from march to may (10.3 ng/ml). the reproductive accessory glands were secretorily active between march and may, and copulation occurred at the end of this period of ac ... | 1991 | 2013875 |
| plasma progesterone and luteinizing hormone concentrations and the role of the corpus luteum and lh gonadotrophs in the control of delayed implantation in schreibers' long-fingered bat (miniopterus schreibersii). | in schreibers' long-fingered bat from south africa (approximately 33 degrees s) copulation, ovulation and fertilization occurred in april and may, implantation was delayed until august, and parturition occurred in december. delayed implantation coincided with winter, during which the bats remained active, only entering prolonged periods of torpor during particularly cold spells. plasma progesterone concentration was low during non-pregnancy (1.54 ng/ml) and during delayed implantation (1.67 ng/m ... | 1991 | 1920296 |
| does similarity in call structure or foraging ecology explain interspecific information transfer in wild myotis bats? | animals can gain important information by attending to the signals and cues of other animals in their environment, with acoustic information playing a major role in many taxa. echolocation call sequences of bats contain information about the identity and behaviour of the sender which is perceptible to close-by receivers. increasing evidence supports the communicative function of echolocation within species, yet data about its role for interspecific information transfer is scarce. here, we asked ... | 2020 | 29200602 |
| [dietary composition, echolocation pulses and morphological measurements of the long-fingered bat miniopterus fuliginosus (chiroptera: vespertilioninae)]. | we investigated food (insect) availability in foraging areas utilized by the long-fingered bat miniopterus fuliginosus using light traps, fish netting and fecal analysis. the dominant preys of m. fuliginosus were lepidoptera (55%, by volume percent) and coleoptera (38%) of a relatively large body size. m. fuliginosus has relatively long, narrow wings and a wing span of 6.58+/-0.12 and high wing loading of 9.85+/-0.83 n/m2. the echolocation calls of free flying m. fuliginosus were fm signals, wit ... | 2011 | 21509962 |
| no apparent ecological trend to the flight-initiating jump performance of five bat species. | the jump performance of five insectivorous bat species (miniopterus schreibersii, myotis blythii, myotis capaccinii, myotis myotis and rhinolophus blasii) was filmed using a high-speed camera. all study bats jumped using a similar technique, with the wing musculature providing the force. the bats jumped off the wrist joint of their wings, typically with their feet already off the ground. contrary to expectations, jump performance did not correlate with ecology and was instead strongly determined ... | 2011 | 21653812 |
| isolation and characterization of microsatellite loci in the long-fingered bat miniopterus fuliginosus. | we isolated and characterized 10 microsatellite loci in the long-fingered bat miniopterus fuliginosus. these loci were tested on 48 individuals from anhui province of china, and all loci were highly polymorphic. the mean number of observed alleles per locus was 13.6 (range from six to 27). observed and expected heterozygosity values ranged from 0.364 to 0.957, and from 0.676 to 0.951, respectively. after bonferroni correction, four loci deviated significantly from hardy-weinberg equilibrium. no ... | 2008 | 21585895 |
| isolation and characterization of microsatellite loci in the western long-fingered bat, miniopterus magnater. | we isolated and characterized 10 microsatellite loci in the western long-fingered bat, miniopterus magnater. these loci were tested on 48 individuals from anhui province of china, and all loci were highly polymorphic. the mean number of observed alleles per locus was 13.6 (range from six to 27). observed and expected heterozygosity values ranged from 0.364 to 0.957, and from 0.676 to 0.951, respectively. after bonferroni correction, four loci deviated significantly from hardy-weinberg equilibriu ... | 2008 | 21586071 |
| retinoic acid-independent expression of meis2 during autopod patterning in the developing bat and mouse limb. | the bat has strikingly divergent forelimbs (long digits supporting wing membranes) and hindlimbs (short, typically free digits) due to the distinct requirements of both aerial and terrestrial locomotion. during embryonic development, the morphology of the bat forelimb deviates dramatically from the mouse and chick, offering an alternative paradigm for identifying genes that play an important role in limb patterning. | 2015 | 25861444 |
| parasites of parasites of bats: laboulbeniales (fungi: ascomycota) on bat flies (diptera: nycteribiidae) in central europe. | bat flies (streblidae and nycteribiidae) are among the most specialized families of the order diptera. members of these two related families have an obligate ectoparasitic lifestyle on bats, and they are known disease vectors for their hosts. however, bat flies have their own ectoparasites: fungi of the order laboulbeniales. in europe, members of the nycteribiidae are parasitized by four species belonging to the genus arthrorhynchus. we carried out a systematic survey of the distribution and fun ... | 2017 | 28222795 |
| discovery of an endogenous deltaretrovirus in the genome of long-fingered bats (chiroptera: miniopteridae). | retroviruses can create endogenous forms on infiltration into the germline cells of their hosts. these forms are then vertically transmitted and can be considered as genetic fossils of ancient viruses. all retrovirus genera, with the exception of deltaretroviruses, have had their representation identified in the host genome as a virus fossil record. here we describe an endogenous deltaretrovirus, identified in the germline of long-fingered bats (miniopteridae). a single, heavily deleted copy of ... | 2017 | 28280099 |
| fishing technique of long-fingered bats was developed from a primary reaction to disappearing target stimuli. | behavioral plasticity is a key feature allowing animals to broaden their dietary niche when novel food resources become available, and long-fingered bats provide an appropriate model system to study the underpinnings of behavioral plasticity, since although generally being an insectivorous species, some individuals have been reported to catch fish. aiming to get insight into the origin of fishing behavior in long-fingered bats, we studied in the field the differences in sensorial and mechanical ... | 2016 | 27973529 |
| excepting myotis capaccinii, the wings' contribution to take-off performance does not correlate with foraging ecology in six species of insectivorous bat. | take-off in bats is separated into two distinct phases: an initial jump and a subsequent wing powered acceleration. here, using footage from a high-speed camera, the first comparative study of the performance during the wing induced phase of take-off in six insectivorous bat species is described. despite distinct differences in foraging strategy, the mass specific power generated by the bats during wing induced take-off did not differ between species, with the exception of myotis capaccinii. thi ... | 2014 | 25326512 |
| fine-tuned echolocation and capture-flight of myotis capaccinii when facing different-sized insect and fish prey. | formerly thought to be a strictly insectivorous trawling bat, recent studies have shown that myotis capaccinii also preys on fish. to determine whether differences exist in bat flight behaviour, prey handling and echolocation characteristics when catching fish and insects of different size, we conducted a field experiment focused on the last stage of prey capture. we used synchronized video and ultrasound recordings to measure several flight and dip features as well as echolocation characteristi ... | 2014 | 25013107 |
| ultrastructural observations of fertilization in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | only a very few spermatozoa were found in the ampulla of the oviduct just after ovulation. the spermatozoa lost both the acrosome cap and the equatorial segment while passing between the cumulus cells surrounding an ampullar egg; many such spermatozoa were found in the perivitelline space. one spermatozoon was seen in contact with the plasma membrane of the ovum in the metaphase of the second meiotic division. excess spermatozoa in the perivitelline space were phagocytosed by pseudopodial protru ... | 1981 | 7196950 |
| fishing long-fingered bats (myotis capaccinii) prey regularly upon exotic fish. | the long-fingered bat myotis capaccinii is a european trawling bat reported to feed on fish in several mediterranean locations, but the ecological circumstances of this behavior have not yet been studied. to elucidate the importance of fishing in this bat's diet, we evaluated the frequency and seasonal variation of fish remains in 3,000 fecal pellets collected from m. capaccinii at a nursery roost in dénia (eastern iberian peninsula) in 2008, 2009, and 2010. fish consumption occurred evenly thro ... | 2013 | 24312200 |
| interspecific acoustic recognition in two european bat communities. | echolocating bats emit echolocation calls for spatial orientation and foraging. these calls are often species-specific and are emitted at high intensity and repetition rate. therefore, these calls could potentially function in intra- and/or inter-specific bat communication. for example, bats in the field approach playbacks of conspecific feeding buzzes, probably because feeding buzzes indicate an available foraging patch. in captivity, some species of bats recognize and distinguish the echolocat ... | 2013 | 23986714 |
| changes in the morphology and behaviour of spermatozoa between copulation and fertilization in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | live spermatozoa were first stored in the colliculus tubaricus of the uterotubal junction (utj) on both sides, spermatozoa then ascended to the caudal isthmus just before ovulation. spermatozoa with intact acrosomes in the caudal isthmus, which had their heads orientated towards the cephalic isthmus, were seen amongst groups of epithelial cilia in parallel to the epithelium; on the other hand, acrosome-less spermatozoa that were not attached to the epithelium were orientated irregularly in the l ... | 1982 | 7077598 |
| hepatitis virus in long-fingered bats, myanmar. | during an analysis of the virome of bats from myanmar, a large number of reads were annotated to orthohepadnaviruses. we present the full genome sequence and a morphological analysis of an orthohepadnavirus circulating in bats. this virus is substantially different from currently known members of the genus orthohepadnavirus and represents a new species. | 2013 | 23631923 |
| the acoustic advantage of hunting at low heights above water: behavioural experiments on the european 'trawling' bats myotis capaccinii, m. dasycneme and m. daubentonii. | we have demonstrated in behavioural experiments that success in capturing prey from surfaces in 'trawling myotis' (leuconoë-type) depends on the acoustic properties of the surface on which the prey is presented. two types of surface structure were ensonified with artificial bat signals to probe their acoustic characteristics. we have shown that perception of prey by echolocation is easier if the prey is presented on a smooth surface (such as calm water) than if it is presented on a structured su ... | 2001 | 11807102 |
| development of the main and accessory placentae in the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | the placentae of the japanese long-fingered bat were characterized by their morphological and functional transition from the main placenta to the accessory placentae. the main placenta transformed from an endotheliodichorial to a haemodichorial (one layer of syncytiotrophoblast and one layer of cytotrophoblast cells) condition. degeneration of the main placenta was accompanied by development of two accessory placentae. these developed on both sides (fetal side) of the main placenta, and subseque ... | 1984 | 6726672 |
| immunocytochemical studies on the pituitary pars distalis of the japanese long-fingered bat, miniopterus schreibersii fuliginosus. | immunocytochemical studies were performed to describe the characteristics of cell types and their distribution in the pars distalis of japanese long-fingered bat, miniopterus schreibersii fuliginosus, collected at various stages of the reproductive cycle. six distinct cell types have been identified in the pars distalis by the unlabeled immunoperoxidase technique and by the abc method. growth hormone (gh) and prolactin (prl) cells were immunostained with antisera against chicken gh and ovine prl ... | 1988 | 3345544 |
| ultrastructural changes in the seminiferous epithelium of two seasonally reproducing bats (mammalia: chiroptera). | the sertoli cells of the cape horseshoe bat (rhinolophus capensis) and schreiber's long-fingered bat (miniopterus schreibersii) undergo marked changes in ultrastructure related to stages in the spermatogenic cycle. the amount of lipid stored in the sertoli cells varies annually and is at a maximum from just after spermiation to early in the following spermatogenic cycle. during spermatogenesis, the diameter of the lipid droplets decreases, reaching a minimum prior to spermiation. sertoli cells e ... | 1989 | 2709418 |
| remnants of an ancient deltaretrovirus in the genomes of horseshoe bats (rhinolophidae). | endogenous retrovirus (erv) sequences provide a rich source of information about the long-term interactions between retroviruses and their hosts. however, most ervs are derived from a subset of retrovirus groups, while ervs derived from certain other groups remain extremely rare. in particular, only a single erv sequence has been identified that shows evidence of being related to an ancient deltaretrovirus, despite the large number of vertebrate genome sequences now available. in this report, we ... | 2018 | 29642581 |
