fine structure of the neck of epididymal spermatozoa of schreiber's long-fingered bat (chiroptera: mammalia).the structure of the spermatozoon of the long-fingered bat (miniopterus schreibersii) was studied using transmission electron microscopy. the neck is characterized by two asymmetrically arranged features that allow the orientation of sections in different planes and therefore aid the interpretation of the structure. there are six segmented columns, two major and four minor, in the anterior 79% of the neck, and it is only posterior to this that the major columns split. one major column is associa ...19883229722
cell entry by a novel european filovirus requires host endosomal cysteine proteases and niemann-pick c1.lloviu virus (llov), a phylogenetically divergent filovirus, is the proposed etiologic agent of die-offs of schreibers's long-fingered bats (miniopterus schreibersii) in western europe. studies of llov remain limited because the infectious agent has not yet been isolated. here, we generated a recombinant vesicular stomatitis virus expressing the llov spike glycoprotein (gp) and used it to show that llov gp resembles other filovirus gp proteins in structure and function. llov gp must be cleaved b ...201425310500
bats in a mediterranean mountainous landscape: does wind farm repowering induce changes at assemblage and species level?we reported data on flying bat assemblages in a mediterranean mountain landscape of central italy on a 5-year time span (2005-2010) where a wind farm repowering has been carried out (from 2009, 17 three-blade turbines substituted an a priori set of one-blade turbines). in 4 yearly based surveys, we calculated a set of univariate metrics at species and assemblage level and also performing a diversity/dominance analysis (k-dominance plots) to evaluate temporal changes. nine species of bats were pr ...201626952112
which factors regulate the reproduction of ectoparasites of temperate-zone cave-dwelling bats?we studied the factors which regulate the reproduction of ectoparasites of temperate-zone cave-dwelling bats, using the schreiber's bat (miniopterus schreibersii) and its ectoparasites as a model. for this, we searched 969 bats during 2003 and 2004 at important stages of the bat yearly cycle and found four ectoparasite species regularly occurring on them: two nycteribiids (nycteribia schmidlii and penicillidia conspicua), one wing mite (spinturnix psi), and one hard tick (ixodes simplex simplex) ...200818779978
population structure of a cave-dwelling bat, miniopterus schreibersii: does it reflect history and social organization?many colonial bat species make regional migrations, and the consequent gene flow may eliminate geographic genetic structure resulting from history of colonization. in this study, we verified that history and social organization have detectable impacts on the genetic structure of miniopterus schreibersii, a cave-dwelling bat with high female philopatry. after studying all known nursing colonies in portugal, we concluded that there is a significant geographic structure and that the overall pattern ...200919494031
oxygen-binding properties of bat hemoglobins.the functional properties of hemolysates from the bats rhinolophus ferrumequinum, miniopterus schreibersi and pipistrellus pipistrellus were studied at 25 degrees c and 37 degrees c over the ph range 7.0-7.4. the concentrations of 2,3-dpg and their effect on hemoglobin o2 affinity were also studied under the same conditions. at ph 7.4 and 37 degrees c hemoglobin o2 affinity was higher than in similarly-sized non-flying, normothermic mammals. the bohr effect values in the three bat species were s ...19911713490
handedness in the echolocating schreiber's long-fingered bat (miniopterus schreibersii).bats, in terms of variety of species and their absolute numbers, are the most successful mammals on earth. the anatomical and functional peculiarities of microchiroptera are not confined only to the auditory system; the wings (hands) of bats are unique both from an anatomical point of view as from a sensorial one. they are much thinner than those of birds and their bony structure is much more similar to a primate hand than to the forelimb of other mammals of the bat's size; the thumb, is very sm ...201020399840
cryptic diversity of the bent-wing bat, miniopterus schreibersii (chiroptera: vespertilionidae), in asia minor.two or more species are cryptic, if they are morphologically similar, biologically distinct, and misclassified as a single species. cryptic species complexes were recently discovered within many bat species and we suspect that the bent-wing bat, miniopterus schreibersii, found in europe, northern africa, and asia minor, could also form such a complex. populations of m. schreibersii decline in most of the european countries and the species is currently listed as near threatened in the iucn red li ...201020433686
energy, water balance and the roost microenvironment in three australian cave-dwelling bats (microchiroptera).the ghost bat, macroderma gigas, and the orange leaf-nosed bat, rhinonycteris aurantius, occupy similar ranges across northern australia and are often found in the same roost caves. both species are considered rare and vulnerable to further population decline. a third small species, the large bent-wing bat, miniopterus schreibersii, has a similar body mass to r. aurantius, but has one of the largest ranges of any australian mammal. in the present study we examine the effect and sensitivity of th ...200011083527
novel lyssavirus in bat, spain.a new tentative lyssavirus, lleida bat lyssavirus, was found in a bent-winged bat (miniopterus schreibersii) in spain. it does not belong to phylogroups i or ii, and it seems to be more closely related to the west causasian bat virus, and especially to the ikoma lyssavirus.201323648051
isolation and phylogenetic characterization of bat astroviruses in southern china.astroviruses are associated with acute gastroenteritis of human and many animal species. recently, two studies have reported that novel astroviruses were found in bats. in order to extensively understand the genetic and phylogenetic characterization of bat astroviruses, we tested fecal samples of nine bat species that were collected at four natural habitats in three areas of southern china. the geographic distributions of the bats involved differed from previous reports. three out of nine specie ...201121573690
insights into persistence mechanisms of a zoonotic virus in bat colonies using a multispecies metapopulation model.rabies is a worldwide zoonosis resulting from lyssavirus infection. in europe, eptesicus serotinus is the most frequently reported bat species infected with lyssavirus, and thus considered to be the reservoir of european bat lyssavirus type 1 (eblv-1). to date, the role of other bat species in eblv-1 epidemiology and persistence remains unknown. here, we built an eblv-1-transmission model based on local observations of a three-cave and four-bat species (myotis capaccinii, myotis myotis, miniopte ...201424755619
the importance of distance to resources in the spatial modelling of bat foraging habitat.many bats are threatened by habitat loss, but opportunities to manage their habitats are now increasing. success of management depends greatly on the capacity to determine where and how interventions should take place, so models predicting how animals use landscapes are important to plan them. bats are quite distinctive in the way they use space for foraging because (i) most are colonial central-place foragers and (ii) exploit scattered and distant resources, although this increases flying costs ...201121547076

assessment of mercury exposure and maternal-foetal transfer in miniopterus schreibersii (chiroptera: miniopteridae) from southeastern iberian peninsula.mercury (hg) is a highly toxic and widely distributed metal that is bioaccumulated in insectivorous mammals and may cause adverse effects on the reproductive system. bats are considered excellent hg bioindicators due to their wide distribution, life span, trophic position, metabolic rate and food intake. however, few studies have analysed hg residues in bats, and to the best of our knowledge, no studies have been made in the iberian peninsula. the main aim of this study was to undertake the firs ...201728028704
candidate new rotavirus species in schreiber's bats, serbia.the genus rotavirus comprises eight species designated a to h and one tentative species, rotavirus i. in a virus metagenomic analysis of schreiber's bats sampled in serbia in 2014 we obtained sequences likely representing novel rotavirus species. whole genome sequencing and phylogenetic analysis classified the representative strain into a tentative tenth rotavirus species, we provisionally called rotavirus j. the novel virus shared a maximum of 50% amino acid sequence identity within the vp6 gen ...201727932285
circum-mediterranean phylogeography of a bat coupled with past environmental niche modeling: a new paradigm for the recolonization of europe?the isolation of populations in the iberian, italian and balkan peninsulas during the ice ages define four main paradigms that explain much of the known distribution of intraspecific genetic diversity in europe. in this study we investigated the phylogeography of a wide-spread bat species, the bent-winged bat, miniopterus schreibersii around the mediterranean basin and in the caucasus. environmental niche modeling (enm) analysis was applied to predict both the current distribution of the species ...201627001602
identification of a novel yersinia enterocolitica strain from bats in association with a bat die-off that occurred in georgia (caucasus).yersinia entercolitica is a bacterial species within the genus yersinia, mostly known as a human enteric pathogen, but also recognized as a zoonotic agent widespread in domestic pigs. findings of this bacterium in wild animals are very limited. the current report presents results of the identification of cultures of y. entercolitica from dead bats after a massive bat die-off in a cave in western georgia. the growth of bacterial colonies morphologically suspected as yersinia was observed from thr ...202032635480
genetic diversity and recombination within bufaviruses: detection of a novel strain in hungarian bats.bats are important hosts of many viruses and in several cases they may serve as natural reservoirs even for viruses with zoonotic potential worldwide, including europe. however, they also serve as natural reservoir for other virus groups with important evolutionary relevance and yet unknown zoonotic potential. we performed viral metagenomic analyses on miniopterus schreibersii bat fecal samples. as a result, a novel parvovirus was detected for the first time in european bats. although, bufavirus ...201525989375
how a haemosporidian parasite of bats gets around: the genetic structure of a parasite, vector and host compared.parasite population structure is often thought to be largely shaped by that of its host. in the case of a parasite with a complex life cycle, two host species, each with their own patterns of demography and migration, spread the parasite. however, the population structure of the parasite is predicted to resemble only that of the most vagile host species. in this study, we tested this prediction in the context of a vector-transmitted parasite. we sampled the haemosporidian parasite polychromophil ...201525641066
the epidemiological characteristics of the korean bat paramyxovirus between 2016 and 2019.bats are considered reservoirs of severe emerging human pathogens. notably, bats host major mammalian paramyxoviruses from the family paramyxoviridae, order mononegavirales. in this study, paramyxoviruses were investigated by reverse transcription semi-nested polymerase chain reaction (rt-semi-nested pcr) and reverse transcription polymerase chain reaction (rt-pcr), based on the rt-semi-nested pcr using the consensus paramyxovirus primers targeting the rna dependent-rna-polymerase (rdrp) region. ...202032512880
