[a lyssavirus with an unusual antigenic structure isolated from a bat in southern kyrgyzstan].examination of 191 specimens of chiroptera in osh province of kyrgyzstan yielded 1 strain of lyssavirus from myotis blythi, the isolate not belonging to serotype 1. the virus was designated aravan by the area of its isolation. its antigenic structure was studied using antinucleocapsid monoclonal antibodies of the wistar institute (philadelphia, isa) and central veterinary laboratory of great britain (waybridge, great britain). the paper presents its antigenic profile, brief characteristics of si ...19921290226
new lyssavirus genotype from the lesser mouse-eared bat (myotis blythi), kyrghyzstan.the aravan virus was isolated from a lesser mouse-eared bat (myotis blythi) in the osh region of kyrghyzstan, central asia, in 1991. we determined the complete sequence of the nucleoprotein (n) gene and compared it with those of 26 representative lyssaviruses obtained from databases. the aravan virus was distinguished from seven distinct genotypes on the basis of nucleotide and amino acid identity. phylogenetic analysis based on both nucleotide and amino acid sequences showed that the aravan vir ...200312643828
variation in ectoparasite load reflects life history traits in the lesser mouse-eared bat myotis blythii (chiroptera: vespertilionidae) in western iran.we studied seasonal variation of ectoparasite load (number of parasites per individual bat) in free-ranging populations of the lesser mouse-eared bat myotis blythii in western iran. data for 1 species each of batfly (nycteribidae), tick (ixodidae), and mite (spinturnicidae) are reported for a 1 yr period. patterns of parasite load during this time differed considerably among species. however, the parasite load increased markedly in pregnant females in spring and early summer. during the same tim ...200818605782
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 ...201728222795
molecular survey of bacterial zoonotic agents in bats from the country of georgia (caucasus).bats are important reservoirs for many zoonotic pathogens. however, no surveys of bacterial pathogens in bats have been performed in the caucasus region. to understand the occurrence and distribution of bacterial infections in these mammals, 218 bats belonging to eight species collected from four regions of georgia were examined for bartonella, brucella, leptospira, and yersinia using molecular approaches. bartonella dna was detected in 77 (35%) bats from all eight species and was distributed in ...201728129398
phylogenetic analyses of bat-associated bugs (hemiptera: cimicidae: cimicinae and cacodminae) indicate two new species close to cimex lectularius.bats are regarded as the primary (ancestral) hosts of bugs of the family cimicidae. the historically and economically most important species in the family is the common bedbug (cimex lectularius), because of its worldwide occurrence and association with humans. this molecular-phylogenetic study was initiated in order to expand the knowledge on the phylogeny of cimicid bugs of bats, by investigating samples from hungary, romania (representing central-eastern europe) and two further countries (sou ...201728934957
viral metagenomic profiling of croatian bat population reveals sample and habitat dependent diversity.to date, the microbiome, as well as the virome of the croatian populations of bats, was unknown. here, we present the results of the first viral metagenomic analysis of guano, feces and saliva (oral swabs) of seven bat species (myotis myotis, miniopterus schreibersii, rhinolophus ferrumequinum, eptesicus serotinus, myotis blythii, myotis nattereri and myotis emarginatus) conducted in mediterranean and continental croatia. viral nucleic acids were extracted from sample pools, and analyzed using i ...202032824037
mitigating the negative impacts of tall wind turbines on bats: vertical activity profiles and relationships to wind speed.wind turbines represent a source of hazard for bats, especially through collision with rotor blades. with increasing technical development, tall turbines (rotor-swept zone 50-150 m above ground level) are becoming widespread, yet we lack quantitative information about species active at these heights, which impedes proposing targeted mitigation recommendations for bat-friendly turbine operation. we investigated vertical activity profiles of a bat assemblage, and their relationships to wind speed, ...201829561851
[calculation of potential accuracy in measuring the angular coordinates of targets by the echolocator of bats using the equal-signal zone method].potential accuracy in measuring the course to a target is calculated. this accuracy is physically achievable it the hypothesis that an accurate measurement of angular coordinates of the target of bat's echolocator is realized by the method similar to that of equally signaling zone in radiolocation is true. possible application of such a method is based on the "pulsation" of direction diagram in the course of radiation of the probing impulse. in this case crossing of partial diagrams of radiation ...2013911913
neurohemal areas bordering the internal cerebral veins in the pineal organ of the bat (myotis blythi oxygnathus). 19863577332
pineal corpora arenacea produced by arachnoid cells in the bat myotis blythi oxygnathus.there are corpora arenacea among the cell layers of the arachnoid on the dorsal surface of the pineal organ of the bat (myotis blythi oxygnathus). the pineal arachnoid consists of electron lucent cells connected by cell injunctions to flat sheets and sandwiched on both sides by electron-dense cell rows. among the superficial cell layers, collagen fibrils form loose bundles. in the electron-lucent cells, pinocytotic vesicles, rough surfaced endoplasmic reticulum, active golgi areas and granular v ...19892756745
short-lived mammals (shrew, mouse) have a less robust metal-responsive transcription factor than humans and bats.non-essential "heavy" metals such as cadmium tend to accumulate in an organism and thus are a particular threat for long-lived animals. here we show that two unrelated, short-lived groups of mammals (rodents and shrews, separated by 100 mio years of evolution) each have independently acquired mutations in their metal-responsive transcription factor (mtf-1) in a domain relevant for robust transcriptional induction by zinc and cadmium. while key amino acids are mutated in rodents, in shrews an ent ...201627067444
variation of parasitism patterns in bats during hibernation: the effect of host species, resources, health status, and hibernation period.during critical periods of food shortage or variable climatic conditions, the choice of an appropriate host can increase the survival and reproductive performance of parasites. in turn, one of the unique adaptations to periodical food shortages is hibernation, which is often found among insectivorous bat species in the temperate zone. while hibernating, bats are completely defenseless against both predators and ectoparasites, their immune and endocrine systems are diminished, and survival is dep ...201627240839
food availability as a major driver in the evolution of life-history strategies of sibling species.life-history theory predicts trade-offs between reproductive and survival traits such that different strategies or environmental constraints may yield comparable lifetime reproductive success among conspecifics. food availability is one of the most important environmental factors shaping developmental processes. it notably affects key life-history components such as reproduction and survival prospect. we investigated whether food resource availability could also operate as an ultimate driver of ...201728649329
[genetic characterization of the uzun-agach virus (uzav, bunyaviridae, nairovirus), isolated from bat myotis blythii oxygnathus monticelli, 1885 (chiroptera; vespertilionidae) in kazakhstan].the complete genome of uzun-agach virus (uzav), isolated from the liver of myotis blythii oxygnathus (monticelli, 1885 (chiroptera; vespertilionidae)) bats in alma-ata district (kazakhstan) in 1977 have been sequenced. based on full-length genome comparison it is shown that uzav is a new member of the nairovirus genus (family bunyaviridae). l-segment and m-segments of uzav have 69,3% and 64,1% identity with issyk-kul virus (iskv) that also was isolated from bats. s-segment of uzav have 99,6% ide ...201425895207
recurrent replacement of mtdna and cryptic hybridization between two sibling bat species myotis myotis and myotis blythii.the two sibling bat species myotis myotis and myotis blythii occur in sympatry over wide areas of southern and central europe. morphological, ecological and previous genetic evidence supported the view that the two species constitute two well-differentiated groups, but recent phylogenetic analyses have shown that the two species share some mtdna haplotypes when they occur in sympatry. in order to see whether some genetic exchange has occurred between the two species, we sequenced a highly variab ...017018432
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 ...201121653812
histopathology of the stomach lesion caused by physaloptera brevivaginata (nematoda:physalopteridae) in bats in spain.physaloptera brevivaginata has been found parasitising the stomach of two species of bats of the family vespertilionidae, myotis myotis and myotis blythii, in spain. a comparative study of the prevalences and mean intensities of parasitism by this physalopterid revealed no statistically significant differences between the two hosts. likewise, no relationship was found between parasite intensity and host body weight. the histopathological study of the stomach lesion revealed destruction of the mu ...19958774770
noctuid moths show neural and behavioural responses to sounds made by some bat-marking rings.coloured rings are often used for marking bats so that specific individuals can be recognized. we noticed that the rings of mouse-eared bats, myotis myotis and myotis blythii, in a combination of one plastic-split and one metallic ring on the same forearm, emitted sounds that were largely ultrasonic each time the rings met in flight. we recorded the ring sounds and the echolocation calls produced by the bats, and played them back to neural preparations of lesser yellow underwing moths, noctua co ...199910202090
discovery and characterization of novel bat coronavirus lineages from kazakhstan.coronaviruses are positive-stranded rna viruses that infect a variety of hosts, resulting in a range of symptoms from gastrointestinal illness to respiratory distress. bats are reservoirs for a high diversity of coronaviruses, and focused surveillance detected several strains genetically similar to mers-coronavirus, sars-coronavirus, and the human coronaviruses 229e and nl63. the bat fauna of central asia, which link china to eastern europe, are relatively less studied than other regions of the ...201930999711
