symbiotic bacteria in the accessory submandibular gland of the club-footed bat, tylonycteris pachypus.	the lumina of the secretory endpieces and, to a lesser extent, of the duct system of the accessory submandibular gland of the club-footed bat, tylonycteris pachypus, contain numerous rod shaped bacteria. despite their abundance, these microbes do not evoke an inflammatory response by the glands. the major submandibular gland, as well as the other major salivary glands in these exotic animals contain no bacteria whatsoever. it is concluded that the bacteria in the accessory submandibular gland ar ...	1995	7741269
karyotype comparison and phylogenetic relationships of pipistrellus-like bats (vespertilionidae; chiroptera; mammalia).	detailed karyotype descriptions of 20 pipistrellus-like bat species belonging to the family vespertilionidae are presented. for the first time, chromosomal complements of four species, i.e. pipistrellus stenopterus (2n = 32), p. javanicus (2n = 34), hypsugo eisentrauti (2n = 42) and h. crassulus (2n = 30) are reported. a pipistrellus kuhlii-like species from madagascar represents a separate species distinguished from the european pipistrellus kuhlii (2n = 44) by a diploid chromosome number of 42 ...	2001	11272789
hierarchical polygyny in multiparous lesser flat-headed bats.	how males gain access to mates and the potential for female choice will determine whether polygyny can operate at several levels, from within litters and groups to the wider population. female lesser flat-headed bats (tylonycteris pachypus) form maternity groups in bamboo stems. unusually for bats, they are multiparous, providing the opportunity to test whether multi-level polygyny differs among males depending on whether they roost with females, with males or are solitary. we genotyped 662 indi ...	2011	21824210
is the discovery of the novel human betacoronavirus 2c emc/2012 (hcov-emc) the beginning of another sars-like pandemic?	fouchier et al. reported the isolation and genome sequencing of a novel coronavirus tentatively named "human betacoronavirus 2c emc/2012 (hcov-emc)" from a saudi patient presenting with pneumonia and renal failure in june 2012. genome sequencing showed that this virus belongs to the group c species of the genus betacoronavirus and phylogenetically related to the bat coronaviruses hku4 and hku5 previously found in lesser bamboo bat and japanese pipistrelle bat of hong kong respectively. another p ...	2012	23072791
dispersal, mating events and fine-scale genetic structure in the lesser flat-headed bats.	population genetic structure has important consequences in evolutionary processes and conservation genetics in animals. fine-scale population genetic structure depends on the pattern of landscape, the permanent movement of individuals, and the dispersal of their genes during temporary mating events. the lesser flat-headed bat (tylonycteris pachypus) is a nonmigratory asian bat species that roosts in small groups within the internodes of bamboo stems and the habitats are fragmented. our previous ...	2013	23349888
[host selection of ectoparasitic gamasid mites on tylonycteris pachypus and t. robustula].	correlations of two species of gamasid mites (macronyssus pararadovskyi and m. radovskyi) and their bat hosts (tylonycteris pachypus and t. robustula) were studied by field surveys and indoor behavioral experiments. the wild data indicated that mite load was positively correlated with body condition index of female t. pachypus hosts (spearman: r (s)=0.55, p<0.01, n=24). whereas, mite loads had no correlation with body condition indexes of male t. pachypus and all t. robustula hosts (p>0.05). ind ...	2013	23389974
[relationships between ectoparasites and grooming behavior of tylonycteris pachypus and t. robustula].	grooming behavior is evolved in animals in response to the costs associated with ectoparasites. in this study, ecotparasite densities and grooming behavior-including licking and scratching-of wild-caught lesser bamboo bat (tylonycteris pachypus) and greater bamboo bat (t. robustula) were analyzed. the results indicated that both the frequencies and durations of licking were higher than those of scratching in both bat species, though t. pachypus licked more but scratched less than t. robustula. t ...	2013	24415692
genetic characterization of betacoronavirus lineage c viruses in bats reveals marked sequence divergence in the spike protein of pipistrellus bat coronavirus hku5 in japanese pipistrelle: implications for the origin of the novel middle east respiratory syndrome coronavirus.	while the novel middle east respiratory syndrome coronavirus (mers-cov) is closely related to tylonycteris bat cov hku4 (ty-batcov hku4) and pipistrellus bat cov hku5 (pi-batcov hku5) in bats from hong kong, and other potential lineage c betacoronaviruses in bats from africa, europe, and america, its animal origin remains obscure. to better understand the role of bats in its origin, we examined the molecular epidemiology and evolution of lineage c betacoronaviruses among bats. ty-batcov hku4 and ...	2013	23720729
a cryptic species of the tylonycteris pachypus complex (chiroptera: vespertilionidae) and its population genetic structure in southern china and nearby regions.	three distinct bamboo bat species (tylonycteris) are known to inhabit tropical and subtropical areas of asia, i.e., t. pachypus, t. robustula, and t. pygmaeus. this study performed karyotypic examinations of 4 specimens from southern chinese t. p. fulvidus populations and one specimen from thai t. p. fulvidus population, which detected distinct karyotypes (2n=30) compared with previous karyotypic descriptions of t. p. pachypus (2n=46) and t. robustula (2n=32) from malaysia. this finding suggeste ...	2014	24550688
replication of mers and sars coronaviruses in bat cells offers insights to their ancestral origins.	previous findings of middle east respiratory syndrome coronavirus (mers-cov)-related viruses in bats, and the ability of tylonycteris-batcov hku4 spike protein to utilize mers-cov receptor, human dipeptidyl peptidase 4 hdpp4, suggest a bat ancestral origin of mers-cov. we developed 12 primary bat cell lines from seven bat species, including tylonycteris pachypus, pipistrellus abramus and rhinolophus sinicus (hosts of tylonycteris-batcov hku4, pipistrellus-batcov hku5, and sars-related-cov respec ...	2018	30531999
discovery of novel bat coronaviruses in south china that use the same receptor as middle east respiratory syndrome coronavirus.	middle east respiratory syndrome coronavirus (mers-cov) has represented a human health threat since 2012. although several mers-related covs that belong to the same species as mers-cov have been identified from bats, they do not use the mers-cov receptor, dipeptidyl peptidase 4 (dpp4). here, we screened 1,059 bat samples from at least 30 bat species collected in different regions in south china and identified 89 strains of lineage c betacoronaviruses, including tylonycteris pachypus coronavirus ...	2018	29669833
rapid detection of mers coronavirus-like viruses in bats: pote1ntial for tracking mers coronavirus transmission and animal origin.	recently, we developed a monoclonal antibody-based rapid nucleocapsid protein detection assay for diagnosis of mers coronavirus (mers-cov) in humans and dromedary camels. in this study, we examined the usefulness of this assay to detect other lineage c betacoronaviruses closely related to mers-cov in bats. the rapid mers-cov nucleocapsid protein detection assay was tested positive in 24 (88.9%) of 27 tylonycteris bat cov hku4 (ty-batcov-hku4) rna-positive alimentary samples of tylonycteris pachy ...	2018	29511173
impact of external odor on self-grooming of lesser flat-headed bats, tylonycteris pachypus.	grooming is a common behavior of some mammals. previous studies have shown that grooming is a means by which animals clean themselves, remove ectoparasites, and lower their body temperature. it is also involved in olfactory communication. bats belong to the order chiroptera and, like most mammals, are the natural host of many ectoparasites. bat grooming, including licking and scratching, is one of the ways to reduce the adverse effects caused by ectoparasites. bat grooming may also be induced by ...	2019	31380075
sars-cov-2: structural diversity, phylogeny, and potential animal host identification of spike glycoprotein.	to investigate the evolutionary history of the current pandemic outbreak of severe acute respiratory syndrome coronavirus 2 (sars-cov-2), a total of 137 genomes of coronavirus strains with release dates between january 2019 and 25 march 2020, were analyzed. to investigate the potential intermediate host of the sars-cov-2, we analyzed spike glycoprotein sequences from different animals, with particular emphasis on bats. we performed phylogenetic analysis and structural reconstruction of the spike ...	2020	32374452
