| recombination within and between species of the alpha proteobacterium bartonella infecting rodents. | bartonella infections from wild mice and voles (apodemus flavicollis, mi. oeconomus, microtus arvalis and myodes glareolus) were sampled from a forest and old-field habitats of eastern poland; a complex network of bartonella isolates, referrable to b. taylorii, b. grahamii, b. birtlesii and b. doshiae, was identified by the sequencing of a glta fragment, comparable to previous studies of bartonella diversity in rodents. nested clade analysis showed that isolates could be assigned to zero- and on ... | 2011 | 20740281 |
| non-human primates in outdoor enclosures: risk for infection with rodent-borne hantaviruses. | different species of non-human primates have been exploited as animal disease models for human hantavirus infections. to study the potential risk of natural hantavirus infection of non-human primates, we investigated serum samples from non-human primates of three species living in outdoor enclosures of the german primate center (gpc), göttingen, located in a hantavirus endemic region of central germany. for that purpose we used serological assays based on recombinant antigens of the bank vole (m ... | 2011 | 20727685 |
| immunolocalization of pthrp in the parotid glands of three rodents species: clethrionomys glareoulus, microtus arvalis and white swiss mice. | the current study was inspired by the fact that since 2004 no report had appeared on the occurrence of this peptide in healthy parotid glands of humans and animals. the objective of the current study was to investigate the immunolocalization of pthrp in the parotid gland of three male rodents: 6 common voles (microtus arvalis, pallas, 1779), 6 bank voles (clethrionomys glareoulus, schreber, 1780) and 6 white swiss mice, as well as to find out any species differences in the distribution of this p ... | 2010 | 20675290 |
| does spatial learning ability of common voles (microtus arvalis) and bank voles (myodes glareolus) constrain foraging efficiency? | place learning abilities represent adaptations that contribute also to foraging efficiency under given spatio-temporal conditions. we investigated if this ability in turn constrains decision making in two sympatric vole species: while the herbivorous common vole (microtus arvalis) feeds on spatio-temporally predictable food resources (e.g. roots, tubers and shoots of plant tubers), the omnivorous bank vole (myodes glareolus) additionally subsists on temporally unpredictable food resources (e.g. ... | 2010 | 20596739 |
| [genomic versus chromosomal polytypy in studies of mitochondrial and nuclear dna markers in the microtus arvalis group]. | common voles of the microtus arvalis group distributed over the territory of european russia are represented by three karyotypic categories, i.e., sympatric sibling species with 2n = 46 and 54, and two allopatric karyoforms in one of them, 2n = 46. for each category, molecular markers were found. for two 46-chromosome forms (arvalis and obscurus), dna was for the first time studied in karyotypes and non-karyotyped specimens for a parapatric hybrid zone, where high diversity of intermediate karyo ... | 2010 | 20583603 |
| [cytogenetic study of the parapatric contact zone between two 46-chromosomal forms of the common vole in european russia]. | since the first description of sympatric sibling species and allopatric chromosomal forms of the common vole (microtus arvalis group) in 1969, the search of their range boundaries has been continually going on up to the present time. based on the cytogenetic material presented in the present study, the geographical distribution of two karyoforms (2n = 46: nf = 84 and nf = 72) was examined in 20 geographic localities of european russia (within the interval between the longitude 34 degrees-56 degr ... | 2010 | 20536021 |
| concentrations of selected heavy metals in bones and femoral bone structure of bank (myodes glareolus) and common (microtus arvalis) voles from different polluted biotopes in slovakia. | concentrations of selected heavy metals in the femora and femoral bone structure of bank (myodes glareolus) and common (microtus arvalis) voles from different polluted biotopes in slovakia (kolíňany and nováky sites) were investigated. length, weight, and histological structure of vole bones were also analyzed. we observed higher concentrations of lead (pb), iron (fe), copper (cu), and zinc (zn) in the bones of both species from the kolíňany site. significant differences were observed in the con ... | 2011 | 20532880 |

| the new species brucella microti replicates in macrophages and causes death in murine models of infection. | the recent isolation of brucella microti from the common vole, the red fox, and the soil raises the possibility of an eventual reemergence of brucellosis in europe. in this work, the pathogenic potential of this new brucella species in both in vitro and in vivo models of infection was analyzed. | 2010 | 20497040 |
| detection of toxoplasma gondii, neospora caninum, and encephalitozoon cuniculi in the brains of common voles (microtus arvalis) and water voles (arvicola terrestris) by gene amplification techniques in western austria (vorarlberg). | knowledge about the protozoan parasite fauna in voles (arvicolinae) in austria is rather limited, although some of these pathogens play an important role in human medicine and cause zoonoses (e.g., toxoplasma gondii and encephalitozoon cuniculi). others are of relevance in veterinary medicine and have a negative economic impact (e.g., neospora caninum). two hundred sixty-eight common voles (microtus arvalis) and 86 water voles (arvicola terrestris) from the most western austrian province, vorarl ... | 2010 | 20480373 |
| difference between random and imprinted x inactivation in common voles. | during early development in female mammals, most genes on one of the two x-chromosomes undergo transcriptional silencing. in the extraembryonic lineages of some eutherian species, imprinted x-inactivation of the paternal x-chromosome occurs. in the cells of the embryo proper, the choice of the future inactive x-chromosome is random. we mapped several genes on the x-chromosomes of five common vole species and compared their expression and methylation patterns in somatic and extraembryonic tissues ... | 2010 | 20473512 |
| predator dietary response to prey density variation and consequences for cestode transmission. | the functional response of predators to prey density variations has previously been investigated in order to understand predation patterns. however, the consequences of functional response on parasite transmission remain largely unexplored. the rodents microtus arvalis and arvicola terrestris are the main prey of the red fox vulpes vulpes in eastern france. these species are intermediate and definitive hosts of the cestode echinococcus multilocularis. we explored the dietary and contamination re ... | 2010 | 20461413 |
| tula virus in populations of small terrestrial mammals in a rural landscape. | over 5 years (2000-2004), populations of small mammals from a rural landscape in southern moravia (czech republic) were investigated for the presence of tula virus (tulv) antigen using the elisa set hantagnost. in total, 1566 individuals from 10 species were examined. the prevalence in the common vole (microtus arvalis pallas 1778), the main reservoir of tulv, was 10% (n = 871). the prevalence of tulv antigen increases with its population numbers. the highest number of tulv antigen-positive comm ... | 2010 | 20420534 |
| the ecology of bartonella spp. infections in two rodent communities in the mazury lake district region of poland. | prevalence and abundance of bartonella spp. infections were studied over a 3-year period in woodland and grassland rodents in north-eastern poland. prevalence of bacterial infections was similar in the two rodent communities, with one leading host species in each habitat (46.3% in apodemus flavicollis versus 29.1% in myodes glareolus in forest, or 36.9% in microtus arvalis versus 13.7% in mi. oeconomus in grassland). prevalence/abundance of infections varied markedly across the 3 years with 2006 ... | 2010 | 20388232 |
| determinants of the prevalence of heligmosomum costellatum (heligmosomidae: trichostrongyloidea) in a common vole population in southern moravia, czech republic. | a study of nematode (heligmosomum costellatum) prevalence in the common vole (microtus arvalis) population was performed in 2002 and 2003 in an agricultural region of southern moravia, czech republic. the influence of the trapping date, body weight, age, gender and reproduction of the common vole on the prevalence of the larvae of h. costellatum encapsulated in the stomach wall was examined. of 503 common voles examined, 27.6% were h. costellatum positive. the prevalence of h. costellatum in the ... | 2010 | 20233485 |
| abctoolbox: a versatile toolkit for approximate bayesian computations. | the estimation of demographic parameters from genetic data often requires the computation of likelihoods. however, the likelihood function is computationally intractable for many realistic evolutionary models, and the use of bayesian inference has therefore been limited to very simple models. the situation changed recently with the advent of approximate bayesian computation (abc) algorithms allowing one to obtain parameter posterior distributions based on simulations not requiring likelihood com ... | 2010 | 20202215 |
| extraintestinal helminths of the common vole (microtus arvalis) and the water vole (arvicola terrestris) in western austria (vorarlberg). | between september and december 2004, a total of 411 voles (318 common voles and 93 water voles) were caught in the austrian province of vorarlberg (lustenau, hohenems, and dornbirn) and were examined by macroscopy, microscopy, and molecular biological analysis to determine the presence and extent of medically important extraintestinal helminths. the following extraintestinal helminth species were detected: taenia taeniaeformis (liver), calodium hepaticum (liver), and echinococcus multilocularis ... | 2010 | 20148339 |
| different cross-reactivity of human and rodent sera to tula virus and puumala virus. | tula virus (tulv) and puumala virus (puuv) are hantaviruses carried by the bank vole (myodes glareolus) and european common vole (microtus arvalis), respectively. puuv is a causative agent of hemorrhagic fever with renal syndrome (hfrs), while tulv is thought to be apathogenic to humans. the n-terminal regions of the n proteins from tulv and puuv were expressed and applied as enzyme-linked immunosorbent assay (elisa) antigens. colonized japanese grass voles (microtus montebelli) and balb/c mice ... | 2010 | 20116854 |
| assessment of low-molecular-weight antioxidants in francisella tularensis infected hosts: comparison of two rodents with different susceptibility to tularemia. | bacterium francisella tularensis is the causative agent of tularemia disease. it is a zoonosis accompanied with high mortality when untreated. small rodents and hares, in particular, are natural reservoirs of tularemia. despite physiological similarity of common hosts, tularemia exerts different mortality rates. the pathogenesis of tularemia is still not fully understood. the main pathway is associated with proliferation in macrophages after activation by reactive oxygen species in phagosomes. | 2009 | 20027169 |
| eco-space: an object-oriented, spatially explicit model to assess the risk of multiple environmental stressors on terrestrial vertebrate populations. | wildlife organisms are exposed to a combination of chemical, biological and physical stressors. information about the relative impact of each stressor can support management decisions, e.g., by the allocation of resources to counteract those stressors that cause most harm. the present paper introduces eco-space; a novel receptor-oriented cumulative exposure model for wildlife species that includes relevant ecological processes such as spatial habitat variation, food web relations, predation, and ... | 2010 | 20005557 |
| [molecular genetic characterization of the regulatory region of the xist gene in the common vole microtus rossiaemeridionalis]. | two conserved regions were discovered as a result of interspecific comparison of the 5'-region of the xist gene, which is the key gene in the process of x-chromosome inactivation in mammalian females. the first region corresponds to the minimal promoter, and the second spans between -480 bp and -400 bp from the start of xist transcription. footprinting experiments revealed protected regions corresponding to the potential binding sites for tbp, sp1, api, sry, er, and some other transcription fact ... | 2009 | 19947545 |
| extensive host sharing of central european tula virus. | to examine the host association of tula virus (tulv), a hantavirus present in large parts of europe, we investigated a total of 791 rodents representing 469 microtus arvalis and 322 microtus agrestis animals from northeast, northwest, and southeast germany, including geographical regions with sympatric occurrence of both vole species, for the presence of tulv infections. based on serological investigation, reverse transcriptase pcr, and subsequent sequence analysis of partial small (s) and mediu ... | 2010 | 19889769 |
| possible interaction between a rodenticide treatment and a pathogen in common vole (microtus arvalis) during a population peak. | a common vole (microtus arvalis) population peak in northern spain in 2007 was treated with large scale application of chlorophacinone, an anticoagulant rodenticide of the indandione family. voles found dead and trapped alive were collected in treated and untreated areas. residues of chlorophacinone were analyzed in liver of voles by hplc-uv. also, the presence of the pathogen francisella tularensis was analyzed by pcr in samples of vole spleen. chlorophacinone (82-3800 ng/g; wet weight liver) w ... | 2009 | 19863999 |
| efficacy and attractiveness of zinc phosphide bait in common voles (microtus arvalis). | minimising the concentration of active ingredient in rodenticide bait is desirable economically and for the protection of the agroecosystem. this study aimed to identify a zinc phosphide concentration that balances palatability and efficacy for common vole (microtus arvalis pall.) management and to compare the attractiveness of two bait carriers. | 2010 | 19798699 |
| fgf4 independent derivation of trophoblast stem cells from the common vole. | the derivation of stable multipotent trophoblast stem (ts) cell lines from preimplantation, and early postimplantation mouse embryos has been reported previously. fgf4, and its receptor fgfr2, have been identified as embryonic signaling factors responsible for the maintenance of the undifferentiated state of multipotent ts cells. here we report the derivation of stable ts-like cell lines from the vole m. rossiaemeridionalis, in the absence of fgf4 and heparin. vole ts-like cells are similar to m ... | 2009 | 19777059 |

| modeling zinc regulation in small mammals. | due to large zinc discharges into the global environment, both terrestrial and aquatic environments have been polluted with zinc. the embanked floodplains of the lower rhine river in the netherlands contain large amounts of heavy metals, including zinc. these large amounts of heavy metals may pose risks to flora and fauna by accumulation in food webs, and risk assessment may be required. however, toxicokinetic models for zinc metabolism in mammalian wildlife species are currently lacking. the pr ... | 2009 | 19642831 |
| spatial and temporal dynamics of lymphocytic choriomeningitis virus in wild rodents, northern italy. | we determined the prevalence of infection with lymphocytic choriomeningitis virus (lcmv) among small mammals in northern italy and analyzed long-term dynamics of lcmv in a rodent population in the province of trento. lcmv is circulating among the most widespread and common wild rodent species in this area (apodemus flavicollis, myodes glareolus, and microtus arvalis); overall prevalence is 6.8%. during 2000-2006, intensive monitoring of lcmv in a population of yellow-necked mice (a. flavicollis) ... | 2009 | 19624914 |
| sex-biased dispersal patterns depend on the spatial scale in a social rodent. | dispersal is a fundamental process in ecology because it influences the dynamics, genetic structure and persistence of populations. furthermore, understanding the evolutionary causes of dispersal pattern, particularly when they differ between genders, is still a major question in evolutionary ecology. using a panel of 10 microsatellite loci, we investigated at different spatial scales the genetic structure and the sex-specific dispersal patterns in the common vole microtus arvalis, a small colon ... | 2009 | 19586945 |
| tularemia induces different biochemical responses in balb/c mice and common voles. | both balb/c mice and common voles (microtus arvalis) are considered highly susceptible to tularemia. however, the common vole is reported to harbour francisella tularensis in european habitats as well as to survive longer with chronic shedding of the bacterium. the purpose of the present study was to compare the response of these two rodents to a wild francisella tularensis subsp. holarctica strain infection. | 2009 | 19558687 |
| patterns of orthopox virus wild rodent hosts in south germany. | although cowpox virus (cpxv) infections in a variety of dead-end hosts have been investigated in germany for more than 50 years, data on species and geographical distribution of cpxv in reservoir hosts are sparse. here we present the first comprehensive study of 825 rodents that have been collected in bavaria, southern germany. in summary, six different rodent species (apodemus flavicollis, myodes glareolus, microtus arvalis, apodemus sylvaticus, microtus agrestis, and arvicola amphibius) were t ... | 2009 | 19492947 |
| morphological modularity and assessment of developmental processes within the vole dental row (microtus arvalis, arvicolinae, rodentia). | knowledge of mammalian tooth formation is increasing, through numerous genetic and developmental studies. the prevalence of teeth in fossil remains has led to an intensive description of evolutionary patterns within and among lineages based on tooth morphology. the extent to which developmental processes have influenced tooth morphologies and therefore the role of these processes in these evolutionary patterns are nonetheless challenging. recent methodological advances have been proposed allowin ... | 2009 | 19469857 |
| new genetic lineage of tula hantavirus in microtus arvalis obscurus in eastern kazakhstan. | genomic sequences of tula (tulv) hantavirus were recovered from tissue samples of european common voles microtus arvalis (subspecies obscurus) captured in kazakhstan, central asia. phylogenetic analysis of the s genomic segment of kazakh tulv strains showed that they form distinct, well supported genetic lineage and share a more ancient common ancestor with two russian lineages of tulv. the deduced sequence of the nucleocapsid (n) protein of kazakh tulv strains carried specific amino acid signat ... | 2008 | 19440462 |
| first molecular evidence of tula hantavirus in microtus voles in slovenia. | different microtus species, present in a worldwide range habitat populating north america, europe, asia, and few other species have been recognized previously as a hantavirus reservoir. tula hantavirus was first reported in microtus arvalis and microtus rossiaemeridionalis from central russia and later discovered in several european countries. using molecular techniques we have demonstrated the presence of tula hantavirus in three different microtus species in slovenia. phylogenetic analyses of ... | 2009 | 19410611 |
| encephalomyocarditis virus infection in wildlife species in greece. | the objective of this work was to search for potential wildlife reservoir hosts of encephalomyocarditis virus (emcv) in wildlife species. from 1994 to 2006, 317 blood and tissue samples were collected from 17 wildlife species in greece. encephalomyocarditis virus was isolated only from two rattus rattus. in addition, antibody to emcv were detected in sera from 39 rattus rattus, one apodemus sylvaticus, one microtus arvalis, and 13 sus scrofa. | 2009 | 19395765 |
| transalpine colonisation and partial phylogeographic erosion by dispersal in the common vole (microtus arvalis). | the colonisation history and genetic structure of the common vole (microtus arvalis) was investigated in the region of the alps by analysing the mitochondrial cytochrome b gene (mtdna) and 19 microsatellite loci (nucdna) for 137 voles from 52 localities. mtdna data provided a much refined distribution of three highly divergent evolutionary lineages in the region compared to previous studies. although high mountain ranges are widely accepted to be barriers for colonisation processes for many orga ... | 2009 | 19389166 |
| kestrel-prey dynamic in a mediterranean region: the effect of generalist predation and climatic factors. | most hypotheses on population limitation of small mammals and their predators come from studies carried out in northern latitudes, mainly in boreal ecosystems. in such regions, many predators specialize on voles and predator-prey systems are simpler compared to southern ecosystems where predator communities are made up mostly of generalists and predator-prey systems are more complex. determining food limitation in generalist predators is difficult due to their capacity to switch to alternative p ... | 2009 | 19234618 |
| spatial genetic structure of a small rodent in a heterogeneous landscape. | gene flow in natural populations may be strongly influenced by landscape features. the integration of landscape characteristics in population genetic studies may thus improve our understanding of population functioning. in this study, we investigated the population genetic structure and gene flow pattern for the common vole, microtus arvalis, in a heterogeneous landscape characterised by strong spatial and temporal variation. the studied area is an intensive agricultural zone of approximately 50 ... | 2008 | 19140985 |
