| [lissavirus in bats residing in the south of west siberia]. | we caught, 2002-2003 in caves of novosibirsk region and altai territory, 52 bats (myotis daubentoni, myotis brandtii, murina leucogaster, plecotus auritus). examinations of the animals' brain samples by fluorescence antibody microscopy and rt-pcr revealed lyssaviruses, genotype 1, which were close to strains provoking rabies in the local animals. according to the results, bats can be involved in keeping alive the rabies foci in western siberia, which must be taken into account in antiepizootic m ... | 2005 | 15747869 |
| isolation of irkut virus from a murina leucogaster bat in china. | bats are recognized as a major reservoir of lyssaviruses; however, no bat lyssavirus has been isolated in asia except for aravan and khujand virus in central asia. all chinese lyssavirus isolates in previous reports have been of species rabies virus, mainly from dogs. following at least two recent bat-associated human rabies-like cases in northeast china, we have initiated a study of the prevalence of lyssaviruses in bats in jilin province and their public health implications. a bat lyssavirus h ... | 2013 | 23505588 |
| characteristics of echolocating bats' auditory stereocilia length, compared with other mammals. | the stereocilia of the organ of corti in 4 different echolocating bats, myotis adversus, murina leucogaster, nyctalus plancyi (nyctalus velutinus), and rhinolophus ferrumequinum were observed by using scanning electron microscopy (sem). stereocilia lengths were estimated for comparison with those of non-echolocating mammals. the specialized lengths of outer hair cells (ohc) stereocilia in echolocating bats were shorter than those of non-echolocating mammals. the specialized lengths of inner hair ... | 2007 | 17653670 |
| acoustic identification of eight species of bat (mammalia: chiroptera) inhabiting forests of southern hokkaido, japan: potential for conservation monitoring. | assessing the impact of forest management on bat communities requires a reliable method for measuring patterns of habitat use by individual species. a measure of activity can be obtained by monitoring echolocation calls, but identification of species is not always straightforward. we assess the feasibility of using analysis of time-expanded echolocation calls to identify free-flying bats in the tomakomai experimental forest of hokkaido university, hokkaido, northern japan. echolocation calls of ... | 2004 | 15459453 |
| a histochemical study on the innervation of the cerebral blood vessels in bats. | the adrenergic and cholinergic nerves innervating the cerebral blood vessels of four species of japanese chiropterids (rhinolophus ferrumequinum, murina leucogaster, vespertilio superans and miniopterus schreibersi) have been investigated using specific histochemical techniques. in all these species of bats arteries of the internal carotid system are poorly developed, whereas those of the vertebro-basilar system are well developed. the adrenergic and cholinergic nerves innervating these cerebral ... | 1981 | 7249047 |
| molecular detection and genotypic characterization of toxoplasma gondii infection in bats in four provinces of china. | toxoplasma gondii is an intracellular protozoan parasite that infects a wide variety of warm-blooded hosts, including humans. limited information about t. gondii infection in bats is available in china. the objective of the present study was to determine prevalence and genetic characterization of t. gondii infection in bats in jilin, liaoning, jiangxi and guangdong provinces, china. | 2014 | 25465220 |
| molecular mechanism underlying muscle mass retention in hibernating bats: role of periodic arousal. | hibernators like bats show only marginal muscle atrophy during prolonged hibernation. the current study was designed to test the hypothesis that hibernators use periodic arousal to increase protein anabolism that compensates for the continuous muscle proteolysis during disuse. to test this hypothesis, we investigated the effects of 3-month hibernation (hb) and 7-day post-arousal torpor (tp) followed by re-arousal (ra) on signaling activities in the pectoral muscles of summer-active (sa) and dorm ... | 2010 | 19847807 |
| overcoming muscle atrophy in a hibernating mammal despite prolonged disuse in dormancy: proteomic and molecular assessment. | prolonged disuse of skeletal muscle causes significant loss of myofibrillar contents, muscle tension, and locomotory capacity. however, hibernating mammals like bats appear to deviate from this trend. although low functional demands during winter dormancy has been implicated as a factor contributing to reduced muscle loss, the precise mechanism that actively prevents muscle atrophy remains unclear. we explored proteomic and molecular assessments of bat muscle to test a hypothesis that expression ... | 2008 | 18181155 |
| seasonal biochemical plasticity of a flight muscle in a bat, murina leucogaster. | cellular and biochemical responses of the pectoral muscle to variation in seasonal activity were studied in the bat, murina leucogaster ognevi. we collected bats in mid-hibernation (february), end-hibernation (april), and mid-summer (august) to track major activity periods in their annual cycle. our findings indicated that myofiber cross-sectional area decreased to 68% between mid- and end-hibernation, but returned to the winter level in mid-summer. total soluble protein and total rna concentrat ... | 2000 | 10936764 |
| behavior and muscle performance in heterothermic bats. | body temperatures of winter-resident korean bats typically range from 10 degrees to 40 degrees c between august and september and from 3 degrees to 15 degrees c between january and april. to learn how behavior and the motor systems of heterothermic bats respond to this body-temperature variation, we examined whole-organism performance and the temperature-dependence of contractile properties of flight muscle in murina leucogaster ognevi. in winter and midspring, the lowest limits of body temperat ... | 2006 | 9634172 |
| using sounds for making decisions: greater tube-nosed bats prefer antagonistic calls over non-communicative sounds when feeding. | bats vocalize extensively within different social contexts. the type and extent of information conveyed via their vocalizations and their perceptual significance, however, remains controversial and difficult to assess. greater tube-nosed bats, murina leucogaster, emit calls consisting of long rectangular broadband noise burst (rbnbl) syllables during aggression between males. to experimentally test the behavioral impact of these sounds for feeding, we deployed an approach and place-preference pa ... | 2016 | 27815241 |
| social and vocal behavior in adult greater tube-nosed bats (murina leucogaster). | many studies have revealed the significant influence of the social nature and ecological niche of a species on the design and complexity of their communication sounds. the knowledge of communication sounds and particularly of the flexibility in their use among mammals, however, remains patchy. being highly vocal and social, bats are well suited for investigating vocal plasticity as well as vocal diversity. thus, the overall aim of this study was to test the presence of structural overlap between ... | 2015 | 25862078 |
| the complete mitogenome of the korean greater tube-nosed bat, murina leucogaster (chiroptera: vespertilionidae). | the complete mitogenome of the korean greater tube-nosed bat murina leucogaster (chiroptera: vespertilionidae) was determined. the mitogenome of m. leucogaster is 16,723 bp in length with a total base composition of 32.8% a, 27.5% t, 25.3% c and 14.4% g. all the protein-coding genes (total length of 11,404 bp) were encoded in h-strand except for nd6 in l-strand. total length of 22 trna genes was 1508 bp varying from 62 bp (trna(ser(agy))) to 74 bp (trna(leu(uur)) and trna(gln)). the 12s rrna and ... | 2016 | 25423531 |
| common occurrence of belerina virus, a novel paramyxovirus found in belgian hedgehogs. | common or european hedgehogs can be found throughout western europe. they are known carriers of a variety of parasitic and bacterial pathogens, and have also been shown to carry several viruses, including morbilli-like paramyxoviruses, although the pathogenic and zoonotic potential of some of these viruses has yet to be determined. we report here the discovery of a novel paramyxovirus in belgian hedgehogs, named belerina virus. the virus was detected by nanopore sequencing of rna isolated from h ... | 2020 | 33168902 |
