anti-brucella agglutinins in bats and "callithrix" monkeys.anti-brucella agglutinins were found in 5 of 53 (9.4%) vampire bats desmodus rotundus, captured in the state of bahia, brasil. two specimens of diphylla ecaudata were negative. fifty specimens of the small monkey, callithrix penicillata, were also negative.1976815569
myobiid mites (trombidiformes: myobiidae) associated with the vampire bats (chiroptera: phyllostomatidae) and information on host taxonomy deduced from them.eudusbabekia diphyllis n. sp. and eudusbabekia diaemis n. sp., parasitic on diphylla ecaudata and diaemus youngi, respectively, are described, and measurements for eudusbabekia arganoi (vomero) are presented. the vampire bats are here treated as representatives of the family phyllostomatidae on the basis of the occurrence of these mites on them. these 3 mites are closest to those parasitic on bats of the genus phyllostomus, among all the known mites of the genus eudusbabekia, suggesting a phylog ...19873598810
comparative karyology of brazilian vampire bats desmodus rotundus and diphylla ecaudata (phyllostomidae, chiroptera): banding patterns, base-specific fluorochromes and fish of ribosomal genes.this paper provides new data on chromosomes of brazilian vampire bats desmodus rotundus and diphylla ecaudata. these species were analyzed by gtg, cbg- and cb-dapi banding, agno3/cma3 sequential staining, base-specific fluorochrome dyes and in situ hybridization with 18s rdna probe. c-banding (cbg) revealed constitutive heterochromatin in the pericentromeric regions in all autosomes and the x and y chromosomes appeared entirely heterochromatic in both species. cb-dapi revealed a coincident bandi ...200111833280
haematophagous bats in brazil, their role in rabies transmission, impact on public health, livestock industry and alternatives to an indiscriminate reduction of bat population.haematophagous bats exist only in latin america, from méxico to the northern provinces of argentina. they are represented by three species, desmodus rotundus, diphylla ecaudata and diaemus youngii. while two species feed only on blood of wild birds, one species, d. rotundus, causes losses feeding on livestock and could be a vector for rabies virus. the cases in which humans were bitten by the bat have increased in brazil. bats became a target of control activities by farming communities and loca ...200314720182
a comparative study of rabies virus isolates from hematophagous bats in brazil.the brazilian chiropteran fauna consists of 167 species; of which, three are hematophagous: the common vampire bat (desmodus rotundus), the white-winged vampire bat (diaemus youngi), and the hairy-legged vampire bat (diphylla ecaudata). the aim of this study was to describe the isolation of rabies virus from common and hairy-legged vampire bats and to report the first comparative antigenic and genetic studies of isolates from these bats. antigenic and genetic typing of both isolates identified t ...201020966291
detection of hantavirus in bats from remaining rain forest in são paulo, brazil.the significant biodiversity found in brazil is a potential for the emergence of new zoonoses. study in some places of the world suggest of the presence to hantavirus in tissues of bats. researches of hantavirus in wildlife, out rodents, are very scarce in brazil. therefore we decided to investigate in tissues of different species of wild animals captured in the same region where rodents were detected positive for this virus. the present work analyzed ninety-one animals (64 rodents, 19 opossums, ...201223259834
chromosomal homologies among vampire bats revealed by chromosome painting (phyllostomidae, chiroptera).substantial effort has been made to elucidate karyotypic evolution of phyllostomid bats, mostly through comparisons of g-banding patterns. however, due to the limited number of g-bands in respective karyotypes and to the similarity of non-homologous bands, an accurate evolutionary history of chromosome segments remains questionable. this is the case for vampire bats (desmodontinae). despite several proposed homologies, banding data have not yet provided a detailed understanding of the chromosoma ...201121178354
bats, primates, and the evolutionary origins and diversification of mammalian gammaherpesviruses.gammaherpesviruses (γhvs) are generally considered host specific and to have codiverged with their hosts over millions of years. this tenet is challenged here by broad-scale phylogenetic analysis of two viral genes using the largest sample of mammalian γhvs to date, integrating for the first time bat γhv sequences available from public repositories and newly generated viral sequences from two vampire bat species (desmodus rotundus and diphylla ecaudata). bat and primate viruses frequently repres ...201627834200
what difference exists in the pancreas of mammals with sanguivorous diet? a morphological, stereological and immunohistochemical study of the pancreatic islets of the hematophagous bat diphylla ecaudata.diphylla ecaudata is a vampire bat that mainly feeds on the blood of birds. this highly specialized diet - hematophagy - is accompanied by a series of morphological changes in the gastro-entero-pancreatic system, since the distribution and relative proportions of different pancreatic endocrine cell types can vary between species due to different physiological conditions and eating habits. the aim of this study was to examine for the first time the pancreas of the vampire bat d. ecaudata using mo ...201323500834
adult vampire bats produce contact calls when isolated: acoustic variation by species, population, colony, and individual.bat pups produce individually distinct isolation calls to facilitate maternal recognition. increasing evidence suggests that, in group-living bat species, adults often use similar calls to maintain contact. we investigated if isolated adults from all three species of the highly cooperative vampire bats (phyllostomidae: desmodontinae) would produce vocally distinct contact calls when physically isolated.201222719947
a comparative study of incisor procumbency and mandibular morphology in vampire bats.the three species of vampire bats (phyllostomidae: desmodontinae), desmodus rotundus, diaemus youngi, and diphylla ecaudata, are the only mammals that obtain all nutrition from vertebrate blood (sanguinivory). because of the unique challenges of this dietary niche, vampire bats possess a suite of behavioral, physiological, and morphological specializations. morphological specializations include a dentition characterized by small, bladelike, non-occlusive cheek teeth, large canines, and extremely ...201020544874
keeping the blood flowing-plasminogen activator genes and feeding behavior in vampire bats.the blood feeding vampire bats emerged from new world leaf-nosed bats that fed on fruit and insects. plasminogen activator, a serine protease that regulates blood coagulation, is known to be expressed in the saliva of desmodus rotundus (common vampire bat) and is thought to be a key enzyme for the emergence of blood feeding in vampire bats. to better understand the evolution of this biological function, we studied the plasminogen activator (pa) genes from all vampire bat species in light of thei ...200918791694
records of bat flies (diptera: nycteribiidae and streblidae) in the semi-arid caatinga in the state of paraíba, northeastern brazil.one of the largest gaps in the knowledge of ectoparasitic flies of the families nycteribiidae and streblidae in brazil is the northeastern region, where most states do not have any record. here, we present the first records of those two bat fly families for the state of paraíba. we recorded a total of 10 species of five genera parasitizing eight bat species of four families. trichobius diphyllae wenzel (streblidae) was the most abundant species, found parasitizing diphylla ecaudata (phyllostomid ...201627562845
