| european bat lyssavirus infection in spanish bat populations. | from 1992 to 2000, 976 sera, 27 blood pellets, and 91 brains were obtained from 14 bat species in 37 localities in spain. specific anti-european bat lyssavirus 1 (ebl1)-neutralizing antibodies have been detected in myotis myotis, miniopterus schreibersii, tadarida teniotis, and rhinolophus ferrumequinum in the region of aragon and the balearic islands. positive results were also obtained by nested reverse transcription-polymerase chain reaction on brain, blood pellet, lung, heart, tongue, and es ... | 2002 | 11971777 |
| environmental exposure to non-essential trace elements in two bat species from urbanised (tadarida teniotis) and open land (miniopterus schreibersii) areas in italy. | bats are particularly suited as bioindicators of trace element pollution due to their longevity and their position in the trophic chain. in this study, the concentrations of ten non-essential trace elements (al, as, ba, cd, hg, pb, sb, sr, th, tl) were determined in the tissues (whole body, skin-fur, skinned body, liver, kidney and bone) of lactant tadarida teniotis from a nursery colony in rome. a large number of bats from this nursery died before fledging and had bone deformities and fractures ... | 2019 | 31465904 |
| seroprevalence of toscana virus and sandfly fever sicilian virus in european bat colonies measured using a neutralization test. | toscana phlebovirus (tosv) and sicilian phlebovirus (sfsv) are endemic in the mediterranean area where they are transmitted to humans by infected sandflies. vertebrates of several species have been postulated to act as reservoirs of these viruses, but convincing evidence is still awaited. among them, bats have been suggested, however documented evidence is lacking. here we tested a total of 329 bats belonging to eight species collected from twelve localities in southern spain for the presence of ... | 2021 | 33440618 |
| first report on extended-spectrum beta-lactamase (esbl) producing escherichia coli from european free-tailed bats (tadarida teniotis) in portugal: a one-health approach of a hidden contamination problem. | the main aim of this study was to characterize the diversity of extended-spectrum beta-lactamases (esbls) in escherichia coli isolates from european free tailed-bats (tadarida teniotis) in portugal. esbl-producing e. coli isolates were recovered from 14 of 146 faecal samples (9.6%) and a total of 19 isolates were completely characterized. the more prevalent beta-lactamase genes detected were blactx-m-1 (57.9%) and blactx-m-3 (36.8%), followed by blashv (31.6%), blatem (21.1%), blaoxa (10.5%) and ... | 2019 | 29290482 |
| how much is enough? effects of technical and biological replication on metabarcoding dietary analysis. | dna metabarcoding is increasingly used in dietary studies to estimate diversity, composition and frequency of occurrence of prey items. however, few studies have assessed how technical and biological replication affect the accuracy of diet estimates. this study addresses these issues using the european free-tailed bat tadarida teniotis, involving high-throughput sequencing of a small fragment of the coi gene in 15 separate faecal pellets and a 15-pellet pool per each of 20 bats. we investigated ... | 2019 | 29940083 |
| active and passive surveillance for bat lyssaviruses in italy revealed serological evidence for their circulation in three bat species. | the wide geographical distribution and genetic diversity of bat-associated lyssaviruses (lysvs) across europe suggest that similar viruses may also be harboured in italian insectivorous bats. indeed, bats were first included within the passive national surveillance programme for rabies in wildlife in the 1980s, while active surveillance has been performed since 2008. the active surveillance strategies implemented allowed us to detect neutralizing antibodies directed towards european bat 1 lyssav ... | 2018 | 30511606 |
| molecular identification of betacoronavirus in bats from sardinia (italy): first detection and phylogeny. | bats may be natural reservoirs for a large variety of emerging viruses, including mammalian coronaviruses (cov). the recent emergence of severe acute respiratory syndrome-associated coronavirus (sars-cov) and middle east respiratory syndrome coronavirus (mers-cov) in humans, with evidence that these viruses may have their ancestry in bats, highlights the importance of virus surveillance in bat populations. here, we report the identification and molecular characterization of a bat β-coronavirus, ... | 2019 | 30426315 |
| 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, ... | 2018 | 29561851 |
| low-frequency echolocation enables the bat tadarida teniotis to feed on tympanate insects. | the european free-tailed bat, tadarida teniotis, forages in uncluttered airspace by using intense narrow-band echolocation calls with low frequency (11-12 khz), and feeds on relatively large flying insects, mainly (90% by volume) of the tympanate orders lepidoptera and neuroptera. the use of low-frequency echolocation calls without strong harmonics appears to be a specialization for long-range detection of large, tympanate insects, which are less well represented in the diet of most other aerial ... | 1994 | 7972162 |
| selective aggressiveness in european free-tailed bats (tadarida teniotis): influence of familiarity, age and sex. | bats are highly social mammals that often form large groups and represent good models to test the role played by individual status in shaping social relationships. social cohesion relies on the ability of group and individual recognition, which is mediated by a range of sensorial cues. in this study, we selected the european free-tailed bat tadarida teniotis as a model species to test the effects of familiarity, sex and age on aggressiveness and mutual tolerance. we hypothesize that t. teniotis ... | 2014 | 24463618 |
| female dietary bias towards large migratory moths in the european free-tailed bat (tadarida teniotis). | in bats, sexual segregation has been described in relation to differential use of roosting and foraging habitats. it is possible that variation may also exist between genders in the use of different prey types. however, until recently this idea was difficult to test owing to poorly resolved taxonomy of dietary studies. here, we use high-throughput sequencing to describe gender-related variation in diet composition of the european free-tailed bat (tadarida teniotis), while controlling for effects ... | 2016 | 27009885 |
| identification of mammalian orthoreovirus type 3 in italian bats. | summary this study describes the isolation and molecular characterization of mammalian orthoreovirus (mrv) in microbats. faecal samples and dead individuals available from rehabilitation centres or collected from known roost sites were virologically tested. in total, 112 carcasses of bats found dead, and 44 faecal samples were analysed. nineteen viral strains were isolated by in vitro cell culture from faecal and tissue samples of different bat species (pipistrellus khulii, tadarida teniotis, rh ... | 2013 | 22931153 |
| seroprevalence dynamics of european bat lyssavirus type 1 in a multispecies bat colony. | we report an active surveillance study of the occurrence of specific antibodies to european bat lyssavirus type 1 (eblv-1) in bat species, scarcely studied hitherto, that share the same refuge. from 2004 to 2012, 406 sera were obtained from nine bat species. blood samples were subjected to a modified fluorescent antibody virus neutralization test to determine the antibody titer. eblv-1-neutralizing antibodies were detected in six of the nine species analyzed (pipistrellus pipistrellus, p. kuhlii ... | 2014 | 25192547 |
| dynamics of jamming avoidance in echolocating bats. | animals using active sensing systems such as echolocation or electrolocation may experience interference from the signals of neighbouring conspecifics, which can be offset by a jamming avoidance response (jar). here, we report jar in one echolocating bat (tadarida teniotis: molossidae) but not in another (taphozous perforatus: emballonuridae) when both flew and foraged with conspecifics. in t. teniotis, jar consisted of shifts in the dominant frequencies of echolocation calls, enhancing differen ... | 2004 | 15306318 |
| energy metabolism and evaporative water loss in the european free-tailed bat and hemprich's long-eared bat (microchiroptera): species sympatric in the negev desert. | we compared the thermoregulatory abilities of two insectivorous bat species, tadarida teniotis (mean body mass 32 g) and otonycteris hemprichii (mean body mass 25 g), that are of different phylogenetic origins and zoogeographic distributions but are sympatric in the negev desert. at night, both were normothermic. by day, both were torpid when exposed to ambient temperatures (t(a)) below 25 degrees celsius, with concomitant adjustments in metabolic rate (mr). otonycteris hemprichii entered torpor ... | 2013 | 16927241 |
