lleida bat lyssavirus isolation in miniopterus schreibersii in france.bat rabies cases are attributed in europe to five different lyssavirus species of 16 recognized lyssavirus species causing rabies. one of the most genetically divergent lyssavirus spp. has been detected in a dead miniopterus schreibersii bat in france. brain samples were found positive for the presence of antigen, infectious virus and viral rna by classical virological methods and molecular methods respectively. the complete genome sequence was determined by next-generation sequencing. the analy ...201930460779
mechanisms for lyssavirus persistence in non-synanthropic bats in europe: insights from a modeling study.bats are natural reservoirs of the largest proportion of viral zoonoses among mammals, thus understanding the conditions for pathogen persistence in bats is essential to reduce human risk. focusing on the european bat lyssavirus subtype 1 (eblv-1), causing rabies disease, we develop a data-driven spatially explicit metapopulation model to investigate eblv-1 persistence in myotis myotis and miniopterus schreibersii bat species in catalonia. we find that persistence relies on host spatial structur ...201930679459
novel circo-like virus detected in a croatian bat population.viral metagenomics analysis of samples from bats has been carried out as part of bat rabies surveillance in croatia. here, we report the complete genome sequence of a novel circo-like virus isolated from a sample of miniopterus schreibersii bat guano determined by illumina next-generation sequencing.201931000554
assessment of the function and intergenus-compatibility of ebola and lloviu virus proteins.sequences for lloviu virus (llov), a putative novel filovirus, were first identified in miniopterus schreibersii bats in spain following a massive bat die-off in 2002, and also recently found in bats in hungary. however, until now it is unclear if these sequences correspond to a fully functional, infectious virus, and whether it will show a pathogenic phenotype like african filoviruses, such as ebola- and marburgviruses, or be apathogenic for humans, like the asian filovirus reston virus. since ...201931017565
hyperparasitism in caves: bats, bat flies and ectoparasitic fungus interaction.bat flies (diptera: nycteribiinae) are highly specialized bloodsucking bat ectoparasites. some of the ectoparasitic bat flies are themselves parasitized with an ectoparasitic fungus of the genus arthrorhynchus (laboulbeniales). ascospores of the fungus attach to the cuticle of a bat fly and develop a haustorium that penetrates the host cuticle. this interaction defines the fungus as a hyperparasite. both the fly and the fungus are obligate parasites and this peculiar case of hyperparasitism has ...201931152770
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 ...201931465904
diversity of borrelia burgdorferi sensu lato species in ixodes ticks (acari: ixodidae) associated with cave-dwelling bats from poland and romania.bats comprise one quarter of the world's mammal species. in europe, three nidicolous ixodes tick species, i. vespertilionis, i. simplex and i. ariadnae are specifically associated with cave-dwelling bats, but their role as potential vectors of zoonotic agents is unknown. in this study, we used pcr-based methods to provide the first evidence of borrelia burgdorferi sensu lato (s.l.) infections in the three bat-associated tick species collected from ten bat species sampled in poland and romania. b ...202031631051
effects of fungal infection on the survival of parasitic bat flies.parasites are able to alter numerous aspects of their hosts' life history, behaviour and distribution. one central question in parasitology is to determine the degree of impact that parasites have on their hosts. laboulbeniales (fungi: ascomycota) are ectoparasitic fungi of arthropods. even though these fungi are widely distributed, little is known about their ecology and their possible physiological effects on their hosts. we used a highly specific bat fly-fungi association to assess the effect ...202031931866
seroreactive profiling of filoviruses in chinese bats reveals extensive infection of diverse viruses.southern china is a hot spot of emerging infectious diseases, in which diverse species of bats dwell, a large group of flying mammals considered natural reservoirs for zoonotic viruses. recently, divergent filoviruses (fivs) have been identified in bats within this region, which pose a potential risk to public health, but the true infection situation in bats remains largely unclear. here, 689 archived bat serum samples were analyzed by enzyme-linked immunosorbent assay (elisa), western blotting, ...202031941778
genomic characterization of a novel bat-associated circovirus detected in european miniopterus schreibersii bats.circoviruses are small circular dna viruses causing severe pig and poultry disease, recently identified in various bat species worldwide. we report the detection and full-genome molecular characterization of a novel bat-associated circovirus identified in faecal samples of miniopterus schreibersii bats (schreiber's bent-winged bats) from sardinia, italy. full-genomic sequencing revealed a new putative member of circoviridae family, with a genome size of 2063 nt. sequencing allowed the characteri ...202032088806
seasonal and geographical distribution of cave-dwelling bats in romania: implications for conservation.caves offer bats refuges for hibernation, breeding and other social events. their quality is important for species distribution. the role of cave microclimate as well as other environmental factors influencing the distribution of cave-dwelling species, is poorly known. we tested the significance of cave variables (length, temperature, elevation, occurrence of water) and geographical location for the presence of bats during hibernation and the breeding season in five regions in romania. to detect ...201132313439
long-term surveillance of bat coronaviruses in korea: diversity and distribution pattern.bats harbour diverse coronaviruses (covs), some of which are associated with zoonotic infections, as well as inter-species transmission. in this study, a total of 512 bat faecal samples from the bat habitats at different geographical locations in south korea were investigated between 2016 and 2019. seventy-eight samples were positive for coronaviruses (15.2%), comprising 68 alphacoronaviruses (13.3%) and 10 betacoronaviruses (2.0%). the positive rates tended to increase during the awakening (apr ...202032473082
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
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
bats out of africa: disentangling the systematic position and biogeography of bats in cabo verde.cabo verde archipelago presents one of the largest knowledge gaps in the distribution and taxonomy of bats in the world. old works indicated that there are five species classified as european taxa. we have conducted an integrative taxonomy to revise the systematic position and distribution of cabo verdean bats with molecular, morphological, and ecological data, to test their native or exotic origin, and infer possible colonization patterns based on fieldwork and museum samples. results showed th ...202032752266
identification and characterization of a novel bat polyomavirus in japan.a novel polyomavirus (pyv) was identified in the intestinal contents of japanese eastern bent-wing bats (miniopterus fuliginosus) via metagenomic analysis. we subsequently sequenced the full genome of the virus, which has been tentatively named miniopterus fuliginosus polyomavirus (mfpyv). the nucleotide sequence identity of the genome with those of other bat pyvs was less than 80%. phylogenetic analysis revealed that mfpyv belonged to the same cluster as pyvs detected in miniopterus schreibersi ...202032816186
viral metagenomic profiling of croatian bat population reveals sample and habitat dependent diversity.to date, the microbiome, as well as the virome of the croatian populations of bats, was unknown. here, we present the results of the first viral metagenomic analysis of guano, feces and saliva (oral swabs) of seven bat species (myotis myotis, miniopterus schreibersii, rhinolophus ferrumequinum, eptesicus serotinus, myotis blythii, myotis nattereri and myotis emarginatus) conducted in mediterranean and continental croatia. viral nucleic acids were extracted from sample pools, and analyzed using i ...202032824037
hydrogen isotopes reveal evidence of migration of miniopterus schreibersii in europe.the schreiber's bat, miniopterus schreibersii, is adapted to long-distance flight, yet long distance movements have only been recorded sporadically using capture-mark-recapture. in this study, we used the hydrogen isotopic composition of 208 wing and 335 fur specimens from across the species' european range to test the hypothesis that the species migrates over long distances.202032993600
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 ...202133440618
