relationships between the parasitic mite spinturnix andegavinus (acari: spinturnicidae) and its bat host, myotis daubentonii (chiroptera: vespertilionidae): seasonal, sex- and age-related variation in infestation and possible impact of the parasite on the host condition and roosting behaviour.	host-parasite relationships between the daubenton's bat, myotis daubentonii kuhl, 1817 (chiroptera: vespertilionidae), and its haematophagous ectoparasite, the mite spinturnix andegavinus kolenati, 1857 (acari: spintumicidae), were subjected to analyses based on data gathered during a six-year study (1999-2004) within a single study area in south bohemia, czech republic. seven hundred and fifty-one daubenton's bats were examined by screening wing membranes with an intensive light source, resulti ...	2006	16898129
seasonal changes in daily torpor patterns of free-ranging female and male daubenton's bats (myotis daubentonii).	daily torpor can provide significant energy and water savings in bats during cold ambient temperatures and food scarcity. however, it may reduce rates of foetal and juvenile development. therefore, reproductive females should optimize development by minimizing times in torpor. to test this hypothesis, the use of torpor by female and male free-ranging daubenton's bats (myotis daubentonii) during reproduction (gestation, lactation, and post-lactation period) was investigated in 1998 and 1999. temp ...	2006	16322980
european bat lyssaviruses: distribution, prevalence and implications for conservation.	worldwide, there are more than 1100 species of the order chiroptera, 45 of which are present in europe, and 16 in the uk. bats are reservoirs of, or can be infected by, several viral diseases, including rabies virus strains (in the lyssavirus genus). within this genus are bat variants that have been recorded in europe; european bat lyssavirus 1 (eblv-1), european bat lyssavirus 2 (eblv-2) and, four currently unclassified isolates. since 1977, 783 cases of eblvs (by isolation of viral rna) have b ...	2006	32226078
sex and segregation in temperate bats.	many temperate insectivorous bats show marked sexual segregation during the summer, but in spectacular, pre-hibernation swarming, gather at caves to mate. in many species, sexual segregation is probably due to a gradient in aerial insect availability that confines females to lower elevations, where high reproductive costs are met by an abundant and reliable food supply. in the hawking and trawling myotis daubentonii, we show that alongside inter-sexual segregation, there is intra-male segregatio ...	2005	16271970
[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
european bat lyssavirus in scottish bats.	we report the first seroprevalence study of the occurrence of specific antibodies to european bat lyssavirus type 2 (eblv-2) in daubenton's bats. bats were captured from 19 sites across eastern and southern scotland. samples from 198 daubenton's bats, 20 natterer's bats, and 6 pipistrelle's bats were tested for eblv-2. blood samples (n = 94) were subjected to a modified fluorescent antibody virus neutralization test to determine antibody titer. from 0.05% to 3.8% (95% confidence interval) of dau ...	2005	15829196

on the taxonomical status of myotis abei yoshikura, 1944 (chiroptera, vespertilionidae).	the type specimen of myotis abei yoshikura, 1944 was examined and compared with species of subgenera leuconoe and selysius from japan and adjacent territories. the analysis of external characters and measurements indicated that m. abei should be recognised as a junior synonym of myotis daubentoni (kuhl, 1817).	2004	15459455
isolation of a european bat lyssavirus type 2 from a daubenton's bat in the united kingdom.	european bat lyssavirus type 2 (eblv-2) has been isolated once previously from a bat in the uk in june 1996. in september 2002, a daubenton's bat (myotis daubentonii) found in lancashire developed abnormal behaviour, including unprovoked aggression, while it was in captivity. brain samples from the bat were tested for virus of the lyssavirus genus, which includes eblv-2 (genotype 6), and classical rabies virus (genotype 1). a positive fluorescent antibody test confirmed that it was infected with ...	2003	12696703
intensity control during target approach in echolocating bats; stereotypical sensori-motor behaviour in daubenton's bats, myotis daubentonii.	when approaching a prey target, bats have been found to decrease the intensity of their emitted echolocation pulses, called intensity compensation. in this paper we examine whether intensity compensation in the echolocation of bats is flexible or stereotyped. we recorded the echolocation calls of daubenton's bats (myotis daubentonii) while the animals attacked targets of different dimensions. myotis daubentonii reduced the peak sound pressure level emitted by about 4db for each halving of distan ...	2002	12177150
the inner ear macular sensory epithelia of the daubenton's bat.	the inner ear macular sensory epithelia of the daubenton's bat were examined quantitatively to estimate the area and total number of hair cells. ultrastructural examination of the sensory epithelium reveals two main types of hair cells: the chalice-innervated hair cell and the bouton-innervated hair cell. the existence of an intermediate type, with a nerve ending covering the lateral side of the hair cell, indicates that the chalice-innervated hair cells are derived from bouton-innervated hair c ...	2001	11559899
continuous hair cell turnover in the inner ear vestibular organs of a mammal, the daubenton's bat (myotis daubentonii).	in both humans and mice the number of hair cells in the inner ear sensory epithelia declines with age, indicating cell death (park et al. 1987; rosenhall 1973). however, recent reports demonstrate the ability of the vestibular sensory epithelia to regenerate after injury (forge et al. 1993, 1998; kuntz and oesterle 1998; li and forge 1997; rubel et al. 1995; tanyeri et al. 1995). still, a continuous hair cell turnover in the vestibular epithelia has not previously been demonstrated in mature mam ...	2000	10663140
first isolation of a rabies-related virus from a daubenton's bat in the united kingdom.	on may 30, 1996, a sick daubenton's bat (myotis daubentonii) was recovered from the cellar of a public house in newhaven, east sussex. its condition deteriorated rapidly, and it was euthanased and examined. positive results, establishing the presence of a rabies or rabies-related virus in its brain, were obtained from the fluorescent antibody test, the rabies tissue culture isolation test, and a hemi-nested reverse-transcription pcr. the complete sequence of the nucleoprotein gene was determined ...	2000	11073000
morphological study of the heart innervation of bats myotis daubentoni and eptesicus serotinus (microchiroptera: vespertilionidae) during hibernation.	the capability of bats to have heart rates fewer than 10 beats/min during hibernation and greater than 700 beats/min during flight surprises biologists and cardiologists. cardioacceleration of hibernating bats is considered to be a function of their intracardiac nervous system. in the present study we investigated the morphology of the heart innervation of ten m. daubentoni and four e. serotinus bats during their natural hibernation in order to determine which intracardiac structures may be invo ...	2000	10916173
wide distribution of short interspersed elements among eukaryotic genomes.	most short interspersed elements (sines) in eukaryotic genomes originate from trna and have internal promoters for rna polymerase iii. the promoter contains two boxes (a and b) spaced by approximately 33 bp. we used oligonucleotide primers specific to these boxes to detect sines in the genomic dna by polymerase chain reaction (pcr). appropriate dna fragments were revealed by pcr in 30 out of 35 eukaryotic species suggesting the wide distribution of sines. the pcr products were used for hybridiza ...	1999	10471819
echolocation behaviour and prey-capture success in foraging bats: laboratory and field experiments on myotis daubentonii.	during prey-capture attempts, many echolocating bats emit a 'terminal buzz', when pulse repetition rate is increased and pulse duration and interpulse interval are shortened. the buzz is followed by a silent interval (the post-buzz pause). we investigated whether variation in the structure of the terminal buzz, and the calls and silent periods following it, may provide information about whether the capture attempt was successful and about the size of prey detected - detail that is valuable in st ...	1999	10359682
ten-year survey of british bats for the existence of rabies.	in 1985, a notable increase in the number of recorded cases of rabies in european bats was observed, indicating a possible spread of the rabies virus in these bats. because of concern that the disease could be introduced into the united kingdom by bats crossing from mainland europe, a programme of screening dead bats for the presence of rabies and rabies-related viruses was initiated at the rabies research and diagnostic unit at the central veterinary laboratory. over a period of 10 years (janua ...	1996	8950819
[the experimental infection of bats with lyssavirus serotypes 1 and 4].	the results of intramuscular inoculation of 111 bats (myotis daubentoni, myotis brandtii) with three strains of lyssaviruses--yuli, stade, and 1150 are presented. bats were found to have low susceptibility, especially to strains of serotype 4. after infection with serotype 4 viruses, fewer bats died but within shorter periods than after infection with serotype 1. after inoculation with strain 1150, 60% of bats yielded virus, whereas only 9-24% did after inoculation with type 4 strains. the survi ...	1992	1471342
polychromophilus murinus: a malarial parasite of bats: life-history and ultrastructural studies.	polychromophilus murinus, a malaria parasite of chiroptera is reported from myotis daubentoni in england. the vector was suspected to be the ectoparasitic nycteribiid fly, nycteribia kolenatii. n. kolenatii collected from wild-caught m. daubentoni were found to have oocysts on the midgut and sporozoites in the salivary glands. wild-caught n. kolenatii were maintained on two wild-caught m. daubentoni harbouring heavy (patent) infections of p. murinus; both oocysts and sporozoites were found in th ...	1988	3136420
hematology of the hibernating bat: myotis daubentoni.	1. hematological parameters in the male and female bats differ only with respect to number and volume of erythrocytes: larger number of smaller cells found in males corresponds to smaller number of larger red blood cells in females, with hemoglobin level and hematocrit values remaining similar in both sexes. 2. six-month-old bats have significantly higher numbers of lymphocytes when compared with adults. 3. there are no significant differences in hemograms (complete blood counts) for bats identi ...	1987	2892639
