| cornea, retina, and lens morphology in five soricidae species (soricomorpha: mammalia). | we analyzed the cornea, retina, and lens of five species of soricidae (pygmy shrew, sorex minutus; common shrew, sorex araneus; millet's shrew, sorex coronatus; water shrew, neomys fodiens; greater white-toothed shrew, crocidura russula) by light and electron microscopy. in all of these species, the corneal epithelium showed a dead cell layer, which may increase the refractive power of the cornea, thereby reducing the hypermetropy that would be expected in a small eye. moreover, the anterior sur ... | 2009 | 19367448 |
| metals in liver and kidneys and the effects of chronic exposure to pyrite mine pollution in the shrew crocidura russula inhabiting the protected wetland of doñana. | historically impacted by anthropogenic activities, the nature reserve of doñana (sw spain) was affected by an unprecedented spillage of mud and acidic water from the aznalcóllar pyrite mine in april 1998. although several studies have addressed the influence of this spill on soils, water, and biota, there is little information on mammals, especially carnivorous species. we measured the concentrations of fe, mg, pb, hg, cd, zn, cu, mn, mo, co, and cr in specimens of the greater white-toothed shre ... | 2009 | 19394996 |
| the timing of the shrew: continuous melatonin treatment maintains youthful rhythmic activity in aging crocidura russula. | laboratory conditions nullify the extrinsic factors that determine the wild expected lifespan and release the intrinsic or potential lifespan. thus, wild animals reared in a laboratory often show an increased lifespan, and consequently an increased senescence phase. senescence is associated with a broad suite of physiological changes, including a decreased responsiveness of the circadian system. the time-keeping hormone melatonin, an important chemical player in this system, is suspected to have ... | 2009 | 19526053 |

| bioaccumulation of metals and effects of a landfill in small mammals part iii: structural alterations. | the leachates from the garraf landfill located in a protected site (ne spain) contain several potentially toxic substances such as heavy metals. here we report the histopathological alterations produced by this pollution in wild specimens of an omnivorous species, the wood mouse, apodemus sylvaticus, and an insectivorous species, the greater white-toothed shrew, crocidura russula. hepatic tissue presented the most severe alterations in both the species, namely cell cycle arrest (apoptosis and ne ... | 2009 | 19758588 |
| characterization of a novel wood mouse virus related to murid herpesvirus 4. | two novel gammaherpesviruses were isolated, one from a field vole (microtus agrestis) and the other from wood mice (apodemus sylvaticus). the genome of the latter, designated wood mouse herpesvirus (wmhv), was completely sequenced. wmhv had the same genome structure and predicted gene content as murid herpesvirus 4 (muhv4; murine gammaherpesvirus 68). overall nucleotide sequence identity between wmhv and muhv4 was 85 % and most of the 10 kb region at the left end of the unique region was particu ... | 2010 | 19940063 |
| ectoparasites (sucking lice, fleas and ticks) of small mammals in southeastern kenya. | during 1998-2000, at least 14 species (n = 309) of small mammals were live-trapped and examined for ectoparasites in moist forests of the taita and shimba hills and drier savannah habitats of nguruman, southeastern kenya. ectoparasites were recorded from 11 species of mammals. five species of sucking lice [hoplopleura inexpectans johnson, h. intermedia kellogg & ferris, polyplax reclinata (nitzsch), p. waterstoni bedford and schizophthirus graphiuri ferris], six species of fleas (ctenophthalmus ... | 2009 | 19941604 |
| distribution of borna disease virus antigen and rna in tissues of naturally infected bicolored white-toothed shrews, crocidura leucodon, supporting their role as reservoir host species. | borna disease is a severe viral-induced disorder of the central nervous system of horses, sheep, and a few other animal species, occurring in certain areas of central europe. pathogenesis and epidemiology of natural borna disease virus (bdv) infections are still not fully understood; several unique epidemiologic features, however, point toward the existence of bdv reservoir populations other than the final hosts. in this study, 69 mice and 12 shrews were trapped and examined. the virus distribut ... | 2010 | 20133953 |
| genetic diversity of imjin virus in the ussuri white-toothed shrew (crocidura lasiura) in the republic of korea, 2004-2010. | recently, imjin virus (mjnv), a genetically distinct hantavirus, was isolated from lung tissues of the ussuri white-toothed shrew (crocidura lasiura) captured near the demilitarized zone in the republic of korea. to clarify the genetic diversity of mjnv, partial m- and l-segment sequences were amplified from lung tissues of 12 of 37 (32.4%) anti-mjnv igg antibody-positive ussuri white-toothed shrews captured between 2004 and 2010. a 531-nucleotide region of the m segment (coordinates 2,255 to 2, ... | 2011 | 21303516 |
| normal and aberrant mesocestoides tetrathyridia from crocidura spp. (soricimorpha) in corsica and spain. | abstract tetrathyridia of mesocestoides sp. were collected from the body cavities of the shrews (soricimorpha), crocidura russula in valencia, spain, and crocidura suaveolens on the mediterranean island of corsica, france. specimens were processed by routine microscopical and histological techniques, including examination with brightfield, phase-contrast, and differential-interference-contrast optics. most tetrathyridia occurred both clustered together inside host-derived fibrotic capsules, but ... | 2011 | 21612421 |
| spatially explicit analysis of metal transfer to biota: influence of soil contamination and landscape. | concepts and developments for a new field in ecotoxicology, referred to as "landscape ecotoxicology," were proposed in the 1990s; however, to date, few studies have been developed in this emergent field. in fact, there is a strong interest in developing this area, both for renewing the concepts and tools used in ecotoxicology as well as for responding to practical issues, such as risk assessment. the aim of this study was to investigate the spatial heterogeneity of metal bioaccumulation in anima ... | 2011 | 21655187 |
| molecular evolution of azagny virus, a newfound hantavirus harbored by the west african pygmy shrew (crocidura obscurior) in cote d'ivoire. | abstract: background: tanganya virus (tgnv), the only shrew-associated hantavirus reported to date from sub-saharan africa, is harbored by the therese's shrew (crocidura theresae), and is phylogenetically distinct from thottapalayam virus (tpmv) in the asian house shrew (suncus murinus) and imjin virus (mjnv) in the ussuri white-toothed shrew (crocidura lasiura). the existence of myriad soricid-borne hantaviruses in eurasia and north america would predict the presence of additional hantaviruses ... | 2011 | 21798050 |
| neospora caninum and toxoplasma gondii in brain tissue of feral rodents and insectivores caught on farms in the netherlands. | we investigated the presence of both neospora caninum and toxoplasma gondii in 250 brain tissue samples from 9 species of feral rodents and insectivores caught on 10 organic farms in the netherlands in 2004. collected samples were conserved in 4% paraformaldehyde solution and analysed by real-time pcr. for n. caninum, 31 samples originating from 6 species tested positive (12.4%): common shrews (33.3%), wood mice (17.6%), harvest mice (16.7%), house mice (15.4%), white-toothed shrews (10.8%) and ... | 2011 | 21958437 |
| [cellular aspects of aging in the pineal gland of the shrew, crocidura russula]. | the greater white-toothed shrew crocidura russula is short-lived species and the phase of senescence is greatly elongated in captivity. the loss of rhythmicity of biological functions that accompanies its aging is also well documented. c. russula is thus an excellent model to test the effects of aging on biological clocks. melatonin is a key hormone in the synchronization of behaviors, metabolisms and physiological regulations with environmental factors. in the present work we want to know if th ... | 2012 | 22226159 |
| divergent ancestral lineages of newfound hantaviruses harbored by phylogenetically related crocidurine shrew species in korea. | spurred by the recent isolation of a novel hantavirus, named imjin virus (mjnv), from the ussuri white-toothed shrew (crocidura lasiura), targeted trapping was conducted for the phylogenetically related asian lesser white-toothed shrew (crocidura shantungensis). pair-wise alignment and comparison of the s, m and l segments of a newfound hantavirus, designated jeju virus (jjuv), indicated remarkably low nucleotide and amino acid sequence similarity with mjnv. phylogenetic analyses, using maximum ... | 2012 | 22230701 |

| complete mitochondrial genome of an asian lesser white-toothed shrew, crocidura shantungensis (soricidae). | the complete mitochondrial genome was sequenced and annotated newly from an individual of crocidura shantungensis (soricidae) from korea. the total length of the c. shantungensis genome is 17,160 bp, with a base composition of 32.5% a, 32.7% t, 21.6% c, and 13.1% g. | 2012 | 23688267 |
| chronic exposure to environmental stressors induces fluctuating asymmetry in shrews inhabiting protected mediterranean sites. | many ecotoxicological studies have addressed the effects of contaminant exposure at various levels of biological organization. however, little information exists on the effects of toxicants on wildlife populations. here we examined exposure of populations of the greater white-toothed shrew crocidura russula (soricomorpha, soricidae) occupying two protected mediterranean sites (a polluted area, the ebro delta, and a control site, garraf massif). bioaccumulation of selected elements (pb, hg, cd, z ... | 2013 | 23800592 |
| bones and genes: resolution problems in three vietnamese species of crocidura (mammalia, soricomorpha, soricidae) and the description of an additional new species. | recent investigations of southeast asian white toothed shrews belonging to the genus crocidura have revealed discrepancies between the results of morphological and molecular studies. the following study concerns three species of crocidura occurring in vietnam, namely crocidura attenuata, crocidura tanakae and crocidura wuchihensis, and an undescribed fourth species revealed by molecular analysis. for many years crocidura attenuata has been known to occur in vietnam but, until very recently, the ... | 2013 | 23840165 |
| does shape co-variation between the skull and the mandible have functional consequences? a 3d approach for a 3d problem. | morpho-functional patterns are important drivers of phenotypic diversity given their importance in a fitness-related context. although modularity of the mandible and skull has been studied extensively in mammals, few studies have explored shape co-variation between these two structures. despite being developmentally independent, the skull and mandible form a functionally integrated unit. in the present paper we use 3d surface geometric morphometric methods allowing us to explore the form of both ... | 2013 | 23964811 |
| differential behavioural and endocrine responses of common voles (microtus arvalis) to nest predators and resource competitors. | adaptive behavioural strategies promoting co-occurrence of competing species are known to result from a sympatric evolutionary past. strategies should be different for indirect resource competition (exploitation, e.g., foraging and avoidance behaviour) than for direct interspecific interference (e.g., aggression, vigilance, and nest guarding). we studied the effects of resource competition and nest predation in sympatric small mammal species using semi-fossorial voles and shrews, which prey on v ... | 2013 | 24010574 |
| responses of wild small mammals to arsenic pollution at a partially remediated mining site in southern france. | partial remediation actions at a former gold mine in southern france led to a mosaic of contaminated and rehabilitated zones. in this study, the distribution of arsenic and its potential adverse effects on small mammals were investigated. the effectiveness of remediation for reducing the transfer of this element into wildlife was also discussed. arsenic levels were measured in the soil and in the stomach contents, livers, kidneys, and lungs of four small mammal species (the wood mouse (apodemus ... | 2014 | 24239822 |

| the bicolored white-toothed shrew crocidura leucodon (hermann 1780) is an indigenous host of mammalian borna disease virus. | borna disease (bd) is a sporadic neurologic disease of horses and sheep caused by mammalian borna disease virus (bdv). its unique epidemiological features include: limited occurrence in certain endemic regions of central europe, yearly varying disease peaks, and a seasonal pattern with higher disease frequencies in spring and a disease nadir in autumn. it is most probably not directly transmitted between horses and sheep. all these features led to the assumption that an indigenous virus reservoi ... | 2014 | 24699636 |
| biodiversity and evolution of imjin virus and thottapalayam virus in crocidurinae shrews in zhejiang province, china. | the recent discovery of numerous hantaviruses in insectivores has provided a new view of hantavirus biodiversity and evolution. to determine the presence and genetic diversity of imjin virus (mjnv) and thottapalayam virus (tpmv) in insectivores in zhejiang province, china, we captured and performed virus screening of 32 ussuri white-toothed shrews (crocidura lasiura) and 105 asian house shrews (suncus murinus) in different coastal regions. hantavirus genome (s, m, and l segments) sequences were ... | 2014 | 24874196 |
| factors associated with the prevalence and pathology of calodium hepaticum and c. splenaecum in periurban micromammals. | calodium hepaticum (syn. capillaria hepatica) and calodium splenaecum (syn. capillaria splenaecum) are nematodes that infect the liver and spleen, respectively, of mammals. while the host range, distribution, pathology and zoonotic potential of c. hepaticum are well known, very little is known about c. splenaecum. the observed prevalence of these two parasites, the factors associated with prevalence, and the lesions resulting in the different host species were studied in 408 micromammals capture ... | 2014 | 24879015 |
| the testis of greater white-toothed shrew crocidura russula in southern european populations: a case of adaptive lack of seasonal involution? | males of all seasonal breeding mammals undergo circannual periods of testis involution resulting in almost complete ablation of the germinative epithelium. we performed a morphometric, histological, hormonal, and gene-expression study of the testes from winter and summer males of the greater white-toothed shrew, crocidura russula, in populations of the southeastern iberian peninsula. unexpectedly, we found no significant differences between the two study groups. surprisingly, female data confirm ... | 2014 | 24895181 |
| invading and expanding: range dynamics and ecological consequences of the greater white-toothed shrew (crocidura russula) invasion in ireland. | establishing how invasive species impact upon pre-existing species is a fundamental question in ecology and conservation biology. the greater white-toothed shrew (crocidura russula) is an invasive species in ireland that was first recorded in 2007 and which, according to initial data, may be limiting the abundance/distribution of the pygmy shrew (sorex minutus), previously ireland's only shrew species. because of these concerns, we undertook an intensive live-trapping survey (and used other data ... | 2014 | 24955824 |
| quadricuspid aortic valves in syrian hamsters and their formation according to current knowledge on valvulogenesis. | occurrence of quadricuspid aortic valves has been reported in humans, in nine dogs and in a greater white-toothed shrew. moreover, two cases of developing aortic valves with four anticipated leaflets have been described in syrian hamster embryos. currently, however, no case of quadricuspid aortic valve in adult hamsters has been recorded. the aim here is to present four adults of this rodent species, two of them with unequivocally quadricuspid aortic valves and the other two with quadricuspid-li ... | 2015 | 25854086 |
| vocal development during postnatal growth and ear morphology in a shrew that generates seismic vibrations, diplomesodon pulchellum. | the ability of adult and subadult piebald shrews (diplomesodon pulchellum) to produce 160hz seismic waves is potentially reflected in their vocal ontogeny and ear morphology. in this study, the ontogeny of call variables and body traits was examined in 11 litters of piebald shrews, in two-day intervals from birth to 22 days (subadult), and ear structure was investigated in two specimens using micro-computed tomography (micro-ct). across ages, the call fundamental frequency (f0) was stable in squ ... | 2015 | 26112702 |
| shedding of infectious borna disease virus-1 in living bicolored white-toothed shrews. | many rna viruses arise from animal reservoirs, namely bats, rodents and insectivores but mechanisms of virus maintenance and transmission still need to be addressed. the bicolored white-toothed shrew (crocidura leucodon) has recently been identified as reservoir of the neurotropic borna disease virus 1 (bodv-1). | 2015 | 26313904 |
| lethal disease in infant and juvenile syrian hamsters experimentally infected with imjin virus, a newfound crocidurine shrew-borne hantavirus. | to gain insights into the pathogenicity of imjin virus (mjnv), a newfound hantavirus isolated from the ussuri white-toothed shrew (crocidura lasiura), groups of syrian hamsters (mesocricetus auratus) of varying ages (<1, 5, 10, 14, 21, 35 and 56 days) were inoculated by the intraperitoneal route with 1000 pfu of mjnv strains 04-55 and 05-11. mjnv-infected syrian hamsters, aged 21 days or less, exhibited reduced activity, weight loss, respiratory distress, hind-limb paralysis and seizures. death ... | 2015 | 26371066 |
| circannual testis changes in seasonally breeding mammals. | in the non-equatorial zones of the earth, species concentrate their reproductive effort in the more favorable season. a consequence of seasonal breeding is seasonal testis regression, which implies the depletion of the germinative epithelium, permeation of the blood-testis barrier, and reduced androgenic function. this process has been studied in a number of vertebrates, but the mechanisms controlling it are not yet well understood. apoptosis was assumed for years to be an important effector of ... | 2015 | 26375035 |
| complete mitochondrial genome of the ussuri white-toothed shrew crocidura lasiura (insectivora, soricidae). | we obtained the complete mitochondrial genome of the ussuri white-toothed shrew crocidura lasiura (insectivora, soricidae) at 17 362 base pairs (bp) containing 13 protein-coding genes, two ribosomal rnas, 22 transfer rnas, and a non-coding control region. its gene order is identical to that of other vertebrates. several repeat elements were identified in the non-coding control region (d-loop). phylogenetic tree using mt protein-coding gene sequences showed that c. lasiura was closely related to ... | 2017 | 26710936 |
| phenotypic flexibility in the energetic strategy of the greater white-toothed shrew, crocidura russula. | the balance between energetic acquisition and expenditure depends on the amount of energy allocated to biological functions such as thermoregulation, growth, reproduction and behavior. ambient temperature has a profound effect on this balance, with species inhabiting colder climates often needing to invest more energy in thermoregulation to maintain body temperature. this leads to local behavioral and physiological adaptations that increase energetic efficiency. in this study, we investigated th ... | 2016 | 26857972 |
| differences in the ectoparasite fauna between micromammals captured in natural and adjacent residential areas are better explained by sex and season than by type of habitat. | we compared the ectoparasite fauna in 608 micromammals (chiefly 472 wood mice apodemus sylvaticus, 63 algerian mice mus spretus, and 51 greater white-toothed shrews crocidura russula) captured in natural and adjacent residential areas in spring and autumn during three consecutive years in four areas in periurban barcelona (ne spain). we found little support for an association of urbanization with differences in infestation by ectoparasites. prevalence of rhipicephalus sp. tick in wood mice and s ... | 2016 | 26946133 |
| prevalence and genotype allocation of pathogenic leptospira species in small mammals from various habitat types in germany. | small mammals serve as most important reservoirs for leptospira spp., the causative agents of leptospirosis, which is one of the most neglected and widespread zoonotic diseases worldwide. the knowledge about leptospira spp. occurring in small mammals from germany is scarce. thus, this study's objectives were to investigate the occurrence of leptospira spp. and the inherent sequence types in small mammals from three different study sites: a forest in southern germany (site b1); a national park in ... | 2016 | 27015596 |
| screening red foxes (vulpes vulpes) for possible viral causes of encephalitis. | next to various known infectious and non-infectious causes, the aetiology of non-suppurative encephalitis in red foxes (vulpes vulpes) often remains unclear. known causes in foxes imply rabies, canine distemper, toxoplasmosis, aujeszky's disease, as well as parvovirus, adenovirus, circovirus and flavivirus infections. in this study, particular attention was paid on bornaviruses, since red foxes are predators of bicoloured white-toothed shrews, a reservoir of borna disease virus 1 (bodv-1). in ad ... | 2016 | 27590473 |
| emerging infectious disease implications of invasive mammalian species: the greater white-toothed shrew (crocidura russula) is associated with a novel serovar of pathogenic leptospira in ireland. | the greater white-toothed shrew (crocidura russula) is an invasive mammalian species that was first recorded in ireland in 2007. it currently occupies an area of approximately 7,600 km2 on the island. c. russula is normally distributed in northern africa and western europe, and was previously absent from the british isles. whilst invasive species can have dramatic and rapid impacts on faunal and floral communities, they may also be carriers of pathogens facilitating disease transmission in poten ... | 2016 | 27935961 |

| infections of horses and shrews with bornaviruses in upper austria: a novel endemic area of borna disease. | borna disease, a lethal infection with borna disease virus-1 (bodv-1), was diagnosed in four horses from upper austria in 2015 and 2016. all cases occurred in winter (two cases in february 2015 and two cases in december 2016), and the maximal distance of the affected stables was 17 km. to demonstrate whether the causative agent was also harbored by its reservoir host, the bicolored white-toothed shrew (crocidura leucodon), 28 shrews from this geographic area were collected in 2015 and investigat ... | 2017 | 28634359 |
| parasitic infections of bicoloured white-toothed shrew (crocidura leucodon) from dasht-e-razan, western iran. | the prevalence and intensity of endo and ectoparasites in shrews inhabiting in the dasht-e razan of hamedan province, iran, were determined in this study. | 2017 | 28761469 |
| ultrastructure of digenean trematode eggs (platyhelminthes: neoophora): a review emphasizing new comparative data on four european microphalloidea. | despite their tremendous diversity and their medical and veterinary importance, details of egg ultrastructure among the digenean trematodes has been studied rather little. the available literature is spread over several decades and several species, but has not been adequately reviewed to reveal patterns of similarity and divergence. we present this review to synthesize and analyse what is known from the available literature reporting studies using both transmission electron microscopy (tem) and ... | 2018 | 29351080 |
| phylogeography of the asian lesser white-toothed shrew, crocidura shantungensis, in east asia: role of the korean peninsula as refugium for small mammals. | many peninsulas in the temperate zone played an important role as refugia of various flora and fauna, and the southern korean peninsula also served as a refugium for many small mammals in east asia during the pleistocene. the asian lesser white-toothed shrew, crocidura shantungensis, is a widely distributed species in east asia, and is an appropriate model organism for exploring the role of the korean peninsula as a refugium of small mammals. here, we investigated phylogenetic relationships and ... | 2018 | 29441472 |
| long-term data from a small mammal community reveal loss of diversity and potential effects of local climate change. | climate change affects distribution and persistence of species. however, forecasting species' responses to these changes requires long-term data series that are often lacking in ecological studies. we used 15 years of small mammal trapping data collected between 1978 and 2015 in 3 areas at doñana national park (southwest spain) to (i) describe changes in species composition and (ii) test the association between local climate conditions and size of small mammal populations. overall, 5 species wer ... | 2017 | 29492011 |
| molecular investigation of vector-borne parasites in wild micromammals, barcelona (spain). | information about the role of micromammals in the epidemiology of leishmania infantum and babesia sp. in southern europe is scarce. wild micromammals were captured in natural areas in the barcelona province (ne spain) in 2011 and analysed by real-time pcr for the presence of dna of piroplasmida (n = 253) and leishmania infantum (n = 166). the wood mouse (apodemus sylvaticus) was the most abundant species, but all specimens tested negative for l. infantum, for which two out of 15 (13.3%) white-to ... | 2018 | 29943318 |
| detection of rabbit hemorrhagic disease virus gi.2/rhdv2/b in the mediterranean pine vole ( microtus duodecimcostatus) and white-toothed shrew ( crocidura russula). | the european wild rabbit ( oryctolagus cuniculus) is a key prey species on the iberian peninsula, and several predator species that are at risk of extinction are dependent on them as prey. a new rabbit hemorrhagic disease (rhd) virus genotype (gi.2/rhdv2/b) emerged in 2010 and posed a threat to wild rabbit populations. during a survey aimed at investigating rhd epidemiology in wild rabbits, gi.2/rhdv2/b was detected by duplex real-time pcr in carcasses of one mediterranean pine vole ( microtus d ... | 2019 | 30226801 |
| characteristics of muscle fiber-type distribution in moles. | moles are a strictly fossorial soricomorpha species and possess a suite of specialized adaptations to subterranean life. however, the contractile function of skeletal muscles in moles remains unclear. we compared muscle fiber-type distribution in two mole species (the large japanese mole and lesser japanese mole) with that in four other soricomorpha species that are semi-fossorial, terrestrial, or semi-aquatic (the japanese shrew-mole, house shrew, japanese white-toothed shrew, and japanese wate ... | 2019 | 30376699 |
| protocol for the reconstruction of micromammals from fossils. two case studies: the skulls of beremendia fissidens and dolinasorex glyphodon. | we have developed a protocol for reconstructing 3d models of the skulls of extinct species of small mammals. for the first time, the reconstruction uses fragments of fossils from a mixture of different specimens and from related extant species. we use free software and commercial computers to make the process reproducible and usable for the scientific community. we present a semi-quantitative protocol to face the problem of making 3d reconstructions of fossil species that are incomplete in the f ... | 2019 | 30893322 |
| the variable heartbeat of japanese moles (mogera spp.). | this report demonstrates the variable cardiac rhythm in two species of subterranean mole, the large japanese mole (mogera wogura) and the lesser japanese mole (mogera imaizumii). the phenomenon was revealed using x-ray videos of m. wogura and investigated in detail using electrocardiogram (ecg) traces recorded with implanted electrodes in this species and m. imaizumii. cessation of heartbeat and extended r-r intervals were observed in the ecgs from both species during short bouts of rest in wake ... | 2019 | 31612249 |
| population dynamics of small endotherms under global change: greater white-toothed shrews crocidura russula in mediterranean habitats. | small endotherms would be especially exposed to main global change drivers (habitat and climate changes) but would also be able to withstand them by adjusting population dynamics locally to changing climate- and habitat-driven food and predation conditions. we analyse the relative importance of changes in climate (mean and variability, including relevant time-lags) and habitat conditions on the abundance, age structure and growth rate of mediterranean populations of a small endotherm, the greate ... | 2020 | 31810679 |
| low prevalence of borna disease virus 1 (bodv-1) igg antibodies in humans from areas endemic for animal borna disease of southern germany. | borna disease virus-1 (bodv-1) was recently discovered as cause of severe and often fatal encephalitis in humans. bodv-1 is known to cause neurological disease in horses and sheep mainly in south and central germany. the virus is maintained in bicolored white-toothed shrews (crocidura leucodon). the incidence of infection and risk factors in humans are completely unresolved. veterinarians may be disproportionally bodv-1-exposed through contact to animals not recognized to be bodv-1 infected. we ... | 2019 | 31882942 |
| multilocus phylogeny and cryptic diversity of white-toothed shrews (mammalia, eulipotyphla, crocidura) in china. | crocidura, the most speciose mammalian genus, occurs across much of asia, europe and africa. the taxonomy of chinese representatives has been studied primarily based on cursory morphological comparisons and their molecular phylogenetic analyses remain unexplored. in order to understand the phylogeny of this group in china, we estimated the first multilocus phylogeny and conducted species delimitation, including taxon sampling throughout their distribution range. | 2020 | 32059644 |
| chromosomal differentiation in genetically isolated populations of the marsh-specialist crocidura suaveolens (mammalia: soricidae). | the genus crocidura represents a remarkable model for the study of chromosome evolution. this is the case of the lesser white-toothed shrew (crocidura suaveolens), a representative of the palearctic group. although continuously distributed from siberia to central europe, c. suaveolens is a rare, habitat-specialist species in the southwesternmost limit of its distributional range, in the gulf of cádiz (iberian peninsula). in this area, c. suaveolens is restricted to genetically isolated populatio ... | 2020 | 32131436 |
| demodex foveolator (acariformes: demodecidae) from crocidura suaveolens (soricomorpha: soricidae) – the second observation worldwide, and a checklist of the demodecid mites of soricomorphs | thus far, only six species of parasitic mites of the demodecidae family have been recorded in hosts from the soricomorpha: two from the common shrew (sorex araneus), two from the mediterranean water shrew (neomys anomalus), one from the lesser white-toothed shrew (crocidura suaveolens) and one from the european mole (talpa europaea). the present study describes the identification of demodex foveolator in c. suaveolens from the area of poland (the wielkopolska region). this is only the second rec ... | 2019 | 32191421 |
| borna disease outbreak with high mortality in an alpaca herd in a previously unreported endemic area in germany. | borna disease virus 1 (bodv-1) is the causative agent of borna disease, an often fatal neurologic condition of domestic mammals, including new world camelids, in endemic areas in central europe. recently, bodv-1 gained further attention by the confirmation of fatal zoonotic infections in humans. although borna disease and bodv-1 have been described already over the past decades, comprehensive reports of borna disease outbreaks in domestic animals employing state-of-the-art diagnostic methods are ... | 2020 | 32223069 |
| geographical distribution of ljungan virus in small mammals in europe. | ljungan virus (lv), which belongs to the parechovirus genus in the picornaviridae family, was first isolated from bank voles (myodes glareolus) in sweden in 1998 and proposed as a zoonotic agent. to improve knowledge of the host association and geographical distribution of lv, tissues from 1685 animals belonging to multiple rodent and insectivore species from 12 european countries were screened for lv-rna using reverse transcriptase (rt)-pcr. in addition, we investigated how the prevalence of lv ... | 2020 | 32487013 |
| molecular survey for cyst-forming coccidia (toxoplasma gondii, neospora caninum, sarcocystis spp.) in mediterranean periurban micromammals. | rodents and other micromammals constitute important reservoirs of infectious diseases; their role in the life cycle of apicomplexan parasites such as toxoplasma gondii, neospora caninum, and sarcocystis spp. still needs clarification. in the present study, we analyzed by pcr and sanger sequencing methods the presence of specific parasite dna within brain and heart tissues of 313 individuals of five synanthropic small mammal species (apodemus sylvaticus, mus spretus, m. musculus, rattus rattus, a ... | 2020 | 32588173 |
| new world camelids are sentinels for the presence of borna disease virus. | borna disease (bd), a frequently fatal neurologic disorder caused by borna disease virus 1 (bodv-1), has been observed for decades in horses, sheep, and other mammals in certain regions of europe. the bicoloured white-toothed shrew (crocidura leucodon) was identified as a persistently infected species involved in virus transmission. recently, bodv-1 attracted attention as a cause of fatal encephalitis in humans. here, we report investigations on bodv-1-infected llamas from a farm in a bd endemic ... | 2021 | 33501762 |
