| the effect of social environment on the immune response of female common voles in matriarchal laboratory groups. | we used the hemagglutination test to investigate differences in the specific immune response to sheep red blood cells (srbc) of female common voles living in matriarchal groups. the applied test proved to be a useful tool for studying the effect of the social environment on the immune response in small mammals. the required blood sampling method did not affect reproductive traits. young female common voles showed a higher immune response than their mothers, which could have been caused by their ... | 2000 | 11150560 |
| prevalence of igg antibodies response to borrelia burgdorferi s.l. in populations of wild rodents from mazury lakes district region of poland. | three rodent species: clethrionomys glareolus, apodemus flavicollis and microtus arvalis from mazury lakes district of poland were examined for antibodies to borrelia burgdorferi by enzyme-labelled protein g assay (elga). c. glareolus had an exceptionally high prevalence of b. burgdorferi antibodies - 58%, but a. flavicollis and m. arvalis also showed significant prevalence of 16.6% and 10.5%, respectively. the elga method is highly specific with good reproducibility. nevertheless, some differen ... | 2000 | 11153035 |
| [analysis of the incidence of tularemia in the breclav district 1994-1999]. | southern moravia is one of the areas where there are long-term natural foci of tularaemia. in 1994 in the breclav district an exacerbation of the disease was recorded in hares. during autumn hunts a positive reaction was recorded in 5.75% of examined hares. an elevated seropositivity persisted also in subsequent years and at the same time a higher human morbidity in the mentioned region. the objective of the investigation was to assess the causes and circumstances which led to the exacerbation o ... | 2001 | 11233673 |
| [organization of extended repeats in heterochromatin in sex chromosomes in the common vole species microtus group "arvalis"]. | two long repeats, ms3 and ms4, are predominantly located in sex-chromosomal heterochromatin in common vole species. their tandem arrangement was revealed by means of the pcr analysis of genomic dnas of four microtus species and by restriction mapping of clones selected from a m. rossiaemeridionalis genomic library. several mobile elements proved incorporated in a monomeric unit of each repeat and amplified together with its other components. in addition, line inserts were found in ms4 tandem arr ... | 2006 | 11234379 |
| experimental transmission of caryospora kutzeri (apicomplexa: eimeriidae) by rodent hosts. | four laboratory-hatched european kestrels falco tinnunculus l. were fed on laboratory mice and common voles microtus arvalis pallas previously inoculated with different doses of sporulated oocysts of caryospora kutzeri böer, 1982. two kestrels that were fed infected mice shed c. kurtzeri oocysts 6 days after ingesting murine tissues. to compare direct and indirect transmissions, two of the kestrels were subsequently directly inoculated with 10(5) sporulated c. kutzeri oocysts and became patent o ... | 2001 | 11266130 |
| findings of mycobacteria in insectivores and small rodents. | the organs of 30 insectivorous mammals and 62 rodents from areas inhabited by people or livestock where cattle paratuberculosis or mycobacterial infections of swine had been found to occur were examined by cultivation during the monitoring of occurrence and spread of mycobacterioses in cattle and swine. mycobacteria were found in the organs of 3 insectivores (10%) and 6 rodents (9.7%). mycobacterium chelonae was isolated from the organs of the lesser white-toothed shrew (crocidura suaveolens) an ... | 2000 | 11271823 |
| comparative chromosome and mitochondrial dna analyses and phylogenetic relationships within common voles (microtus, arvicolidae). | the four species of common voles within the genus microtus--m. kirgisorum, m. transcaspicus, m. arvalis, and m. rossiaemeridionalis--are so closely related that neither morphological features nor paleontological evidence allow clarification of their phylogeny. analysis of vole karyotypes and mitochondrial dna sequences, therefore, is essential for determining their phylogenetic relationships. a comparison of high resolution gtg-banding patterns allows us to ascertain the similarity between the k ... | 2001 | 11321366 |
| characterization of the genomic xist locus in rodents reveals conservation of overall gene structure and tandem repeats but rapid evolution of unique sequence. | the xist locus plays a central role in the regulation of x chromosome inactivation in mammals, although its exact mode of action remains to be elucidated. evolutionary studies are important in identifying conserved genomic regions and defining their possible function. here we report cloning, sequence analysis, and detailed characterization of the xist gene from four closely related species of common vole (field mouse), microtus arvalis. our analysis reveals that there is overall conservation of ... | 2001 | 11337478 |
| is high prevalence of echinococcus multilocularis in wild and domestic animals associated with disease incidence in humans? | we investigated a focus of highly endemic echinococcus multilocularis infection to assess persistence of high endemicity in rural rodents, explore potential for parasite transmission to domestic carnivores, and assess (serologically) putative exposure versus infection frequency in inhabitants of the region. from spring 1993 to spring 1998, the prevalence of e. multilocularis in rodents was 9% to 39% for arvicola terrestris and 10% to 21% for microtus arvalis. from june 1996 to october 1997, 6 (7 ... | 2001 | 11384517 |
| [gene for structural proteins of the smc family in the common vole microtus arvalis]. | genes for four subfamilies of smc (structural maintenance of chromosomes) proteins have been isolated from the genome of a common vole microtus arvalis. the high degree of homology between representatives of each smc protein subfamily of different classes of organisms has been demonstrated. the full-sized copy of a mammalian gene encoding smc4 protein has been isolated and analyzed for the first time. the smc proteins enter into the composition of complexes responsible for cohesion of sister chr ... | 2006 | 11443917 |
| importance of surveillance of tularemia natural foci in the known endemic area of central europe, 1991-1997. | marked activation of natural foci of tularemia in the known endemic area of central europe, comprising the borderland of slovakia, austria and the czech republic, led to an epidemic outbreak in western slovakia and an increase in the number of human tularemia cases in the adjoining regions of northeastern austria and southern moravia from 1995 to 1997. the aim of this paper was to present the results of a longitudinal study on the prevalence of infection with francisella tularensis in small mamm ... | 2001 | 11467089 |
| a new geographical gradient in vole population dynamics. | a new geographical gradient in the dynamics of small rodents is demonstrated by analysing 29 time series of density indices of the common vole (microtus arvalis) from poland, the czech republic and the slovak republic. this gradient extends from more stable northerly populations in coastal poland to more variable and cyclic populations in the southernmost parts of the slovak republic, and is hence a reversal of the fennoscandian gradient. all studied variables (such as mean density, cycle amplit ... | 2001 | 11487400 |
| susceptibility of common voles to experimental toxoplasmosis. | common voles (microtus arvalis) in groups of nine to 10 animals were inoculated per os with a dose of 1, 10, 1x10(2), 1x10(3), and of the k1 strain of toxoplasma gondii. all the common voles inoculated with 1 to 1 x 10(3) oocysts remained subclinical and survived. three of the 10 voles inoculated with 1 x 10(4) oocysts died between days 7 and 12 post inoculation (p.i.). antibodies were demonstrated in all the infected voles killed on day 60 p.i. the highest antibody titres in voles detected by t ... | 2001 | 11504242 |
| [chromosomal and ontogenetic instability in sibling species of common vole (microtus arvalis group): comparative aspects]. | populations of chromosomal sibling species microtus arvalis and microtus rossiaemeridionalis were studied in ural region in habitats affected by high radiation and the control ones. frequency of chromosome disturbances in the marrow cells and fluctuating asymmetry (fa) of 8 craniometric characters were investigated. in impact populations the frequency of chromosome aberration was very high. such frequency was also maintained in the offspring of the first laboratory generation of m. arvalis. in n ... | 2001 | 11548401 |

| [specific features of nitrogen transformation in the soddy-podzolic soil in the areas of habitat of the common vole microtus arvalis]. | the influence of common vole microtus arvalis on processes of nitrogen fixation and denitrification in the soddy-podsolic soil was studied. in the common vole colonies, the level of nitrogen fixation was reliably lower and that of denitrification higher, than in the control soil outside these colonies. nitrogen-containing excretory products of voles accumulating in the soil are among the main factors that determine the activity of these processes. | 2017 | 12068433 |
| utility of chromosomal position of heterochromatin as a biomarker of radiation-induced genetic damage: a study of chornobyl voles (microtus sp.). | biomarkers that effectively document effects of chronic multi-generational exposure to contaminated environments on chromosomes would be valuable in risk assessment, remediation, and environmental decisions. native, free-ranging populations of voles inhabiting the highly radioactive regions surrounding reactor 4 of the chornobyl nuclear power station provide a model system to evaluate biological and chromosomal effects of chronic multi-generational exposure to radioactivity and other reactor mel ... | 2002 | 12092749 |
| prevalence and abundance of cryptosporidium parvum and giardia spp. in wild rural rodents from the mazury lake district region of poland. | prevalence and abundance of cryptosporodium parvum and giardia spp. were studied in 3 species of rodents from forests and abandoned agricultural fields in n.e. poland (clethrionomys glareolus n = 459; microtus arvalis n = 274; apodemus flavicollis n = 209). overall prevalence was consistently higher in the voles compared with a. flavicollis (70.6, 73.0 and 27.8% respectively for c. parvum and 93.9, 96.3 and 48.3% respectively for giardia spp.). prevalence and abundance of infection also varied m ... | 2002 | 12166517 |
| chromatid gaps as a marker of mutagenic effect of environmental pollution in commensal and wild rodents of the ural mountains. | it was supposed earlier that achromatic gaps could be used as markers of mutagenic effect of environmental pollution, especially under weaker clastogenic influences. the frequencies of true chromosome aberrations and those of chromatid gaps were estimated in house mice and common voles from uralian localities with various mutagenic potential of environment. gaps and breaks were distinguished according to the cbis system. in several localities, rodents displayed highly significant increase of the ... | 2002 | 12379012 |
| prevalence of coinfection with francisella tularensis in reservoir animals of borrelia burgdorferi sensu lato. | studies on lyme borreliosis and other tick-borne zoonoses in the austrian and slovakian borderland, a region endemic for tularemia, revealed a relatively high prevalence of infection with borrelia burgdorferi s.l. and francisella tularensis in small terrestrial mammals, as well as in the ticks, during a one-year survey. the occurrence of coinfection with the agents of lyme borreliosis and tularemia was assessed in different species of rodents. | 2002 | 12422587 |
| distribution of hantavirus foci in belgium. | during 1999 and 2000, we performed rodent captures on 15 sites all over belgium to evaluate the presence of hantaviruses in local rodent populations. viral antibody and rna detection was performed by elisa/focus reduction neutralisation test and rt-pcr, respectively. we found hantavirus-positive rodents on 13 out of 15 trapping sites and 3 rodent species were found positive for hantavirus infection. apart from puumala virus that was carried by clethrionomys glareolus, 2 additional rodent species ... | 2002 | 12443796 |

| genetic evidence for tula virus in microtus arvalis and microtus agrestis populations in croatia. | to determine the threat of hantavirus infection to u.s. forces, small mammals were sampled from training areas within croatia. of the 152 samples, 20 were positive for tula virus (tul), 12 common voles (microtus arvalis) and eight field voles (microtus agrestis). sequences from m. agrestis were found in five and sequences from m. arvalis were found in six of seven sequence groups. the high percentage of the same tul sequences in m. agrestis and m. arvalis suggests the co-occurrence of this virus ... | 2002 | 12656127 |
| immunolocalization of pthrp in the sublingual glands of three mammals. | the present study deals with immunohistochemical localization of pthrp in sublingual glands of white mouse, bank vole, and common vole. pthrp immunoreactivity was observed in epithelial cells of striated, interlobular and main excretory ducts of the salivary glands in all the three animal species tested. however, we found no positive reaction for pthrp in epithelial cells of the intercalated ducts. in striated duct cells, the reaction intensity was species-dependent. in bank vole and common vole ... | 2003 | 12705476 |
| phylogeography of the common vole (microtus arvalis) with particular emphasis on the colonization of the orkney archipelago. | to investigate the human introduction of the common vole microtus arvalis onto the orkney islands, the complete cytochrome b gene was sequenced in 41 specimens from both orkney (four localities) and elsewhere in their range (26 localities). orkney voles belonged to the same phylogenetic lineage, 'western', as individuals from france and spain indicating southwestern europe as the most likely source area for the islands. this result is of interest with respect to the movement and trading links of ... | 2003 | 12753214 |
| holarctic phylogeography of the root vole (microtus oeconomus): implications for late quaternary biogeography of high latitudes. | a species-wide phylogeographical study of the root vole (microtus oeconomus) was performed using the whole 1140 base pair mitochondrial (mt) cytochrome b gene. we examined 83 specimens from 52 localities resulting in 65 unique haplotypes. our results demonstrate that the root vole is divided into four main mtdna phylogenetic lineages that seem to have largely allopatric distributions. net divergence estimates (2.0-3.5%) between phylogroups, as well as relatively high nucleotide diversity estimat ... | 2003 | 12753215 |
| [isolation of es-like lines of common voles of the genus microtus from blastocysts and germ cells and as a result of the fusion of somatic cells with mouse embryonic stem cells]. | three and four independent cell lines with limited pluripotency were obtained from the inner cell mass cells of blastocysts and primordial germ cells of common voles, respectively. the results of cytogenetic analysis suggest that all these lines originated from the embryos of f1 microtus rossiaemeridionalis x m. arvalis males and had a great number of near-triploid cells already during the early passages. the cells of these lines, like those of the inner cell mass, were characterized by the alka ... | 2003 | 12816050 |
| echinococcus multilocularis: secondary poisoning of fox population during a vole outbreak reduces environmental contamination in a high endemicity area. | this paper describes the role of fox population level on echinococcus multilocularis infection in foxes in a highly endemic area in eastern france. fox population level was monitored by spotlight survey at le souillot from 1989 to 2000, and from 1992 to 2000 at chemin, a control site located in a low endemic area. the infection level of the fox population was estimated at le souillot from winter 1995 to winter 1999 using a coproantigen elisa performed on faeces collected in the field. population ... | 2003 | 12906878 |
