| increased radiation from chernobyl decreases the expression of red colouration in natural populations of bank voles (myodes glareolus). | pheomelanin is a pink to red version of melanin pigment deposited in skin and hair. due to its bright colour, pheomelanin plays a crucial function in signalling, in particular sexual signalling. however, production of pheomelanin, as opposed to its dark alternative, eumelanin, bears costs in terms of consumption of antioxidants important for protection of dna against naturally produced reactive oxidative species. therefore, decreased expression of pheomelanin is expected in organisms exposed to ... | 2014 | 25413373 |
| [a hantavirus killed an israeli researcher: hazards while working with wild animals]. | an israeli researcher working in finland with bank voles, contracted an infectious viral disease and died. this was a rare event, but it is important to learn about this class of viruses and to be aware of the hazards while working in the field in close contact with wild animals. the virus termed puumala belongs to the genus hanta from the bunyaviridae family. the natural reservoir is rodents, mice, rats and bank votes for the puuamala strain. the disease is termed hfrs (hemorrhagic fever with r ... | 2014 | 25286630 |
| regulation of forest defoliating insects through small mammal predation: reconsidering the mechanisms. | population densities of forest defoliating insects may be regulated by small mammal predation on the pupae. when outbreaks do occur, they often coincide with warm, dry weather and at barren forest sites. a proposed reason for this is that weather and habitat affect small mammal population density (numerical response) and hence pupal predation. we propose an alternative explanation: weather and habitat affect small mammal feeding behaviour (functional response) and hence the outbreak risks of for ... | 2014 | 25234375 |
| effect of copper exposure on reproductive ability in the bank vole (myodes glareolus). | the amount of copper in natural ecosystems is steadily increasing, due to human activities. it accumulates in plants, posing a threat to herbivores. in polluted areas the population density of small rodents is observed to be lower. the decline in rodent numbers may be caused by increased mortality or diminished fertility. this study examined the effect of copper on the reproductive activity of the bank vole (myodes glareolus), a small rodent which during foraging often wanders into fields where ... | 2014 | 25098774 |
| learning ability in bank voles selected for high aerobic metabolism, predatory behaviour and herbivorous capability. | although great progress has been made in understanding neurological mechanisms of cognitive processes, the questions concerning interrelation between evolution of cognitive abilities and evolution of diverse life histories and adaptive strategies remains largely open. we approached the problem using a unique experimental evolution model system: lines of bank voles selected for high swim-induced aerobic metabolism, intensity of predatory behaviour towards crickets, and ability to grow on a low-qu ... | 2014 | 24952259 |
| spontaneous expression of magnetic compass orientation in an epigeic rodent: the bank vole, clethrionomys glareolus. | magnetoreception has been convincingly demonstrated in only a few mammalian species. among rodents, magnetic compass orientation has been documented in four species of subterranean mole rats and two epigeic (i.e. active above ground) species-the siberian hamster and the c57bl/6j mouse. the mole rats use the magnetic field azimuth to determine compass heading; their directional preference is spontaneous and unimodal, and their magnetic compass is magnetite-mediated. by contrast, the primary compo ... | 2014 | 24913128 |
| immunogenetic factors affecting susceptibility of humans and rodents to hantaviruses and the clinical course of hantaviral disease in humans. | we reviewed the associations of immunity-related genes with susceptibility of humans and rodents to hantaviruses, and with severity of hantaviral diseases in humans. several class i and class ii hla haplotypes were linked with severe or benign hantavirus infections, and these haplotypes varied among localities and hantaviruses. the polymorphism of other immunity-related genes including the c4a gene and a high-producing genotype of tnf gene associated with severe puuv infection. additional genes ... | 2014 | 24859344 |
| effects of chemical and thermal stress on acetylcholinesterase activity in the brain of the bank vole, myodes glareolus. | one of the most important issues in ecotoxicology is better understanding the effects of interactions between chemical pollutants and physical environmental factors on animals. to fill this knowledge gap, changes in the activity of acetylcholinesterase (ache) in the brain samples of bank voles myodes (clethrionomys) glareolus due to temperature effects, and two chemical stressors were studied in a full factorial laboratory experiment (27 treatments). the experiment was divided into three phases: ... | 2014 | 24853134 |
| genetic variation in bank vole populations in natural and metal-contaminated areas. | the effects of isolation and heavy-metal pollution on genetic diversity in myodes (=clethrionomys) glareolus populations were studied. isolation and pollution are considered to have important effects on biodiversity. animals were collected from ten populations in isolated (island), mainland, and metal-polluted areas. three populations were in areas near zinc and lead smelters; four were on islands in the relatively unpolluted mazurian lake district and in the bieszczady mountains; and three were ... | 2014 | 24840501 |
| adaptive phylogeography: functional divergence between haemoglobins derived from different glacial refugia in the bank vole. | over the years, researchers have used presumptively neutral molecular variation to infer the origins of current species' distributions in northern latitudes (especially europe). however, several reported examples of genic and chromosomal replacements suggest that end-glacial colonizations of particular northern areas may have involved genetic input from different source populations at different times, coupled with competition and selection. we investigate the functional consequences of differenc ... | 2014 | 24827438 |
| positive selection on mhc class ii drb and dqb genes in the bank vole (myodes glareolus). | the major histocompatibility complex (mhc) class iib genes show considerable sequence similarity between loci. the mhc class ii dqb and drb genes are known to exhibit a high level of polymorphism, most likely maintained by parasite-mediated selection. studies of the mhc in wild rodents have focused on drb, whilst dqb has been given much less attention. here, we characterised dqb genes in swedish bank voles myodes glareolus, using full-length transcripts. we then designed primers that specificall ... | 2014 | 24748547 |
| do photoperiod and endocrine disruptor 4-tert-octylphenol effect on spermatozoa of bank vole (clethrionomys glareolus)? | photoperiod is an environmental signal that controls physiology and behavior of all organisms. bank voles, which are seasonal breeders, are stimulated to reproduce by the long photoperiod associated with spring and summer. to date, physiology of bank vole spermatozoa has not been explored, although they constitute an interesting model for examining the relationship between photoperiod and xenoestrogen on spermatozoa function. in an attempt to evaluate the acute effect of 4-tert-octylphenol (op) ... | 2014 | 24698786 |
| molecular and ecological signs of mitochondrial adaptation: consequences for introgression? | the evolution of the mitochondrial genome and its potential adaptive impact still generates vital debates. even if mitochondria have a crucial functional role, as they are the main cellular energy suppliers, mitochondrial dna (mtdna) introgression is common in nature, introducing variation in populations upon which selection may act. here we evaluated whether the evolution of mtdna in a rodent species affected by mtdna introgression is explained by neutral expectations alone. variation in one mi ... | 2014 | 24690754 |
| relaxed functional constraints on triplicate α-globin gene in the bank vole suggest a different evolutionary history from other rodents. | gene duplication plays an important role in the origin of evolutionary novelties, but the mechanisms responsible for the retention and functional divergence of the duplicated copy are not fully understood. the α-globin genes provide an example of a gene family with different numbers of gene duplicates among rodents. whereas rattus and peromyscus each have three adult α-globin genes (hba-t1, hba-t2 and hba-t3), mus has only two copies. high rates of amino acid evolution in the independently deriv ... | 2014 | 24595364 |
| polyandrous females produce sons that are successful at post-copulatory competition. | some of the genetic benefit hypotheses put forward to explain multiple male mating (polyandry) predict that sons of polyandrous females will have an increased competitive ability under precopulatory or post-copulatory competition via paternally inherited traits, such as attractiveness or fertilization efficiency. here, we tested these predictions by comparing the competitive ability of sons of experimentally monandrous and polyandrous female bank voles (myodes glareolus), while controlling for p ... | 2014 | 24517341 |
| [radiation doses and allozyme variability in the population of the northern red-backed vole (clethrionomys rutilus) from the east urals radioactive trace zone]. | the paper estimates the external (due to radionuclides accumulated in the soil) and internal (due to incorporated radionuclides) exposure of rodents that live in the head of the east urals radioactive trace (eurt). it is shown that in the last decades the dose rates were lower than the values that lead to doubling the number of mutations in the allozyme loci in mammals. the variability ofthe eight allozyme loci in populations of northern red-backed voles from the eurt zone and their neighboring ... | 2014 | 25711026 |
| concurrent effects of age class and food distribution on immigration success and population dynamics in a small mammal. | during the settlement stage of dispersal, the outcome of conflicts between residents and immigrants should depend on the social organization of resident populations as well as on individual traits of immigrants, such as their age class, body mass and/or behaviour. we have previously shown that spatial distribution of food influences the social organization of female bank voles (myodes glareolus). here, we aimed to determine the relative impact of food distribution and immigrant age class on the ... | 2014 | 24256406 |
| accuracy of allele frequency estimation using pooled rna-seq. | for nonmodel organisms, genome-wide information that describes functionally relevant variation may be obtained by rna-seq following de novo transcriptome assembly. while sequencing has become relatively inexpensive, the preparation of a large number of sequencing libraries remains prohibitively expensive for population genetic analyses of nonmodel species. pooling samples may be then an attractive alternative. to test whether pooled rna-seq accurately predicts true allele frequencies, we analyse ... | 2014 | 24119300 |
| no alad polymorphism in bank vole populations from unpolluted and lead-zinc polluted areas in poland. | although a variety of biomarkers has been developed to assess the adverse effect of lead on human and animal populations, studies show that the most important factor conditioning the response may be the genetic make-up of an individual. alad (delta aminolevulinic acid dehydratase) gene polymorphism found in human populations results in the existence of two alleles: alad1 and alad2. the difference between them is the result of one nucleotide change (g177c, rs1800435) which implicates different en ... | 2015 | 26103685 |
| on the systematic position of collyricloides massanae vaucher, 1969 (platyhelminthes: digenea) with notes on distribution of this trematode species. | the systematic position of the collyricloides massanae, a rare cyst-dwelling parasite, located on intestinal wall of european birds and rodents, have always been controversial. based on newly obtained sequences of the 28 sdna of c. massanae from avian and rodent host from central europe, and on the previously published sequences of several genera and families among microphalloidea, we evaluate its taxonomic position and the phylogenetic relationships within the genera collyriclum kossack, 1911 a ... | 2015 | 25638231 |
| octylphenol induces changes in glycosylation pattern, calcium level and ultrastructure of bank vole spermatozoa in vitro. | our previous studies revealed that in bank vole testicular cells octylphenol (op) action is related either to its binding to estrogen receptors or increasing camp level that modulates spermatozoa motility and acrosome reaction (ar), (kotula-balak et al., 2011, 2014). to better understand the mechanisms underlying these changes, in the present study we aimed at evaluating the glycosylation pattern, calcium (ca(2+)) level and ultrastructure of op-treated vole spermatozoa. glycans were recognized b ... | 2015 | 25553917 |
| mitogenomic phylogenetics of the bank vole clethrionomys glareolus, a model system for studying end-glacial colonization of europe. | we have revisited the mtdna phylogeny of the bank vole clethrionomys glareolus based on sanger and next-generation illumina sequencing of 32 complete mitochondrial genomes. the bank vole is a key study species for understanding the response of european fauna to the climate change following the last glacial maximum (lgm) and one of the most convincing examples of a woodland mammal surviving in cryptic northern glacial refugia in europe. the genomes sequenced included multiple representatives of e ... | 2015 | 25450101 |
| selection for high activity-related aerobic metabolism does not alter the capacity of non-shivering thermogenesis in bank voles. | an intriguing question is how the capacity of non-shivering thermogenesis (nst)-a special mechanism supporting endothermic thermoregulation in mammals-is affected by selection for high exercise metabolism. it has been proposed that high nst could be a mechanism to compensate for a low basal production of heat. on the other hand, high basal or activity metabolism is associated with physiological characteristics such as high performance of the circulatory system, which are also required for achiev ... | 2015 | 25446149 |
| reproduction is not costly in terms of oxidative stress. | one of the core assumptions of life-history theory is the negative trade-off between current and future reproduction. investment in current reproduction is expected to decrease future reproductive success or survival, but the physiological mechanisms underlying these costs are still obscure. to test for a role of oxidative stress, we measured oxidative damage to lipids and proteins in liver, heart, kidneys and muscles, as well as the level of antioxidants (total glutathione and catalase), in bre ... | 2015 | 26519508 |
| mapping 3' transcript ends in the bank vole (clethrionomys glareolus) mitochondrial genome with rna-seq. | although posttranscriptional modification of mitochondrial (mt) transcripts plays key roles in completion of the coding information and in the expression of mtdna-encoded genes, there is little experimental evidence on the polyadenylation status and the location of mt gene poly(a) sites for non-human mammals. | 2015 | 26503603 |
| correction: bank vole prion protein as an apparently universal substrate for rt-quic-based detection and discrimination of prion strains. | 2015 | 26284358 | |
| temporal trends in the levels of polychlorinated dioxins, -furans, -biphenyls and polybrominated diethyl ethers in bank voles in northern finland. | dioxin-like chemicals and brominated flame retardants are ubiquitous in the environment, despite the introduction of international prohibitions and restrictions. these chemicals do not remain in the vicinity of their source, instead they can be transported over long distances, in fact even to pristine areas in the northern latitudes. however, there have been rather few time series experiments monitoring the trends in the levels of chlorinated and brominated forms of these chemicals in the enviro ... | 2015 | 25918894 |
| evolution of basal metabolic rate in bank voles from a multidirectional selection experiment. | a major theme in evolutionary and ecological physiology of terrestrial vertebrates encompasses the factors underlying the evolution of endothermy in birds and mammals and interspecific variation of basal metabolic rate (bmr). here, we applied the experimental evolution approach and compared bmr in lines of a wild rodent, the bank vole (myodes glareolus), selected for 11 generations for: high swim-induced aerobic metabolism (a), ability to maintain body mass on a low-quality herbivorous diet (h) ... | 2015 | 25876844 |
| correlation between infectivity and disease associated prion protein in the nervous system and selected edible tissues of naturally affected scrapie sheep. | the transmissible spongiform encephalopathies (tses) or prion diseases are a group of fatal neurodegenerative disorders characterised by the accumulation of a pathological form of a host protein known as prion protein (prp). the validation of abnormal prp detection techniques is fundamental to allow the use of high-throughput laboratory based tests, avoiding the limitations of bioassays. we used scrapie, a prototype tse, to examine the relationship between infectivity and laboratory based diagno ... | 2015 | 25807559 |
| [a modular approach to studying of fluctuating asymmetry of complex morphological structures in rodents with the mandible of the bank vole (clethrionomys glareolus, arvicolinae, rodentia) as an example]. | the expediency of a modular approach to estimating fluctuating asymmetry (fa) of complex morphological structures was shown using the mandible of the bank vole (clethrionomys glareolus schreber, 1780) as an example. fa of the shape of two mandibular regions (modules) defined developmentally and functionally, was assessed by means of geometric morphometrics. the differences between mandibular regions in the fa levels were found for both individual landmarks and integral indices of asymmetry. rega ... | 2015 | 25782276 |
| initial molecular-level response to artificial selection for increased aerobic metabolism occurs primarily through changes in gene expression. | experimental evolution combined with genome or transcriptome resequencing (evolve and resequence) represents a promising approach for advancing our understanding of the genetic basis of adaptation. here, we applied this strategy to investigate the effect of selection on a complex trait in lines derived from a natural population of a small mammal. we analyzed the liver and heart transcriptomes of bank voles (myodes [=clethrionomys] glareolus) that had been selected for increased aerobic metabolis ... | 2015 | 25739734 |
| seasonal dynamics of products of lipid peroxidation in liver of bank vole (myodes glareolus) under conditions of environmental pollution by heavy metals. | the presented research involves the integral assessment of biochemistry indexes of natural populations of voles under conditions of environmental pollution by heavy metals. the raised content of mobile forms of pb, cd, cr, ni and co in soils was revealed for a distance of 500 m to the south-west of tripillya thermal power plant (tpp) (kyiv region, ukraine). it considerably (up to 3-5 times) exceeds the levels in the territory of kaniv nature reserve (cherkassy region, ukraine). the territory of ... | 2015 | 24479334 |
| effect of selection for high activity-related metabolism on membrane phospholipid fatty acid composition in bank voles. | endothermy, high basal metabolic rates (bmrs), and high locomotor-related metabolism were important steps in the evolution of mammals. it has been proposed that the composition of membrane phospholipid fatty acids plays an important role in energy metabolism and exercise muscle physiology. in particular, the membrane pacemaker theory of metabolism suggests that an increase in cell membrane fatty acid unsaturation would result in an increase in bmr. we aimed to determine whether membrane phosphol ... | 2015 | 26658414 |
| female host sex-biased parasitism with the rodent stomach nematode mastophorus muris in wild bank voles (myodes glareolus). | abundance and prevalence of helminth infections often differ between host sexes, and are usually biased in favor of males. relatively few cases of female-biased parasitism have been reported. we sampled bank voles in three woodland sites in n.e. poland over 11 years at 3-4-year intervals, and assessed their parasite burdens. prevalence and abundance of the stomach nematode mastophorus muris were consistently higher among females. among adult female bank voles from the two sites that showed the h ... | 2015 | 25395256 |
| possible role of different animal species in maintenance and spread of murine gammaherpesvirus 68 in the nature. | murine gammaherpesvirus 68 (mhv-68), isolated from a bank vole (clethrionomys glareolus) in slovakia in 1976 is a natural pathogen of wild murid rodents. this review is focused to biological properties of this pathogen, the mode of its maintenance in murid rodents as reservoir animals, mechanisms of its spread to other animals in the same biotope as well as to livestock and household animals. potential role of ticks as vectors and the possibility of infection of humans with this virus are consid ... | 2015 | 25790046 |
| genome characterisation of two ljungan virus isolates from wild bank voles (myodes glareolus) in sweden. | ljungan virus (lv) (family picornaviridae, genus parechovirus) is a suspected zoonotic pathogen with associations to human disease in sweden. lv is a single-stranded rna virus with a positive sense genome. there are five published ljungan virus strains, three isolated from sweden and two from america, and are classified into four genotypes. a further two strains described here were isolated from wild bank voles (myodes glareolus) caught in västmanlands county, sweden in 1994. these strains were ... | 2015 | 26375731 |
| spatiotemporal dynamics of puumala hantavirus associated with its rodent host, myodes glareolus. | many viruses significantly impact human and animal health. understanding the population dynamics of these viruses and their hosts can provide important insights for epidemiology and virus evolution. puumala virus (puuv) is a european hantavirus that may cause regional outbreaks of hemorrhagic fever with renal syndrome in humans. here, we analyzed the spatiotemporal dynamics of puuv circulating in local populations of its rodent reservoir host, the bank vole (myodes glareolus) during eight years. ... | 2015 | 26136821 |
| physiological condition of bank voles (myodes glareolus) during the increase and decline phases of the population cycle. | the dynamics of animal populations are greatly influenced by interactions with their natural enemies and food resources. however, quantifying the relative effects of these factors on demographic rates remains a perpetual challenge for animal population ecology. food scarcity is assumed to limit the growth and to initiate the decline of cyclic herbivore populations, but this has not been verified with physiological health indices. we hypothesized that individuals in declining populations would ex ... | 2015 | 26006298 |
| age-related effects of chronic hantavirus infection on female host fecundity. | 1. pathogens often cause detrimental effects to their hosts and, consequently, may influence host population dynamics that may, in turn, feed back to pathogen transmission dynamics. understanding fitness effects of pathogens upon animal host populations can help to predict the risks that zoonotic pathogens pose to humans. 2. here we determine whether chronic infection by puumala hantavirus (puuv) affects important fitness-related traits, namely the probability of breeding, reproductive effort an ... | 2015 | 25965086 |
| landscape and regional environmental analysis of the spatial distribution of hantavirus human cases in europe. | in europe, the most prevalent hantavirus, puumala virus, is transmitted by bank voles and causes nephropathia epidemica in human. the european spatial distribution of nephropathia epidemica is investigated here for the first time with a rich set of environmental variables. | 2015 | 25874194 |
| serological survey of seewis virus antibodies in patients suspected for hantavirus infection in finland; a cross-reaction between puumala virus antiserum with seewis virus n protein? | puumala virus (puuv, carried by myodes glareolus) co-circulates with seewis virus (swsv, carried by sorex araneus) in finland. while puuv causes 1000-3000 nephropathia epidemica (ne) cases annually, the pathogenicity of swsv to man is unknown. to study the prevalence of swsv antibodies in hantavirus fever-like patients' sera, we used recombinant swsv nucleocapsid (n) protein as the antigen in elisa, immunofluorescence assay (ifa) and immunoblotting. while characterizing the recombinant swsv n pr ... | 2015 | 25787939 |
| life-long shedding of puumala hantavirus in wild bank voles (myodes glareolus). | the knowledge of viral shedding patterns and viraemia in the reservoir host species is a key factor in assessing the human risk of zoonotic viruses. the shedding of hantaviruses (family bunyaviridae) by their host rodents has widely been studied experimentally, but rarely in natural settings. here we present the dynamics of puumala hantavirus (puuv) shedding and viraemia in naturally infected wild bank voles (myodes glareolus). in a monthly capture-mark-recapture study, we analysed 18 bank voles ... | 2015 | 25701819 |
| climate variability and the occurrence of human puumala hantavirus infections in europe: a systematic review. | hantaviruses are distributed worldwide and are transmitted by rodents. in europe, the infection usually manifests as a mild form of haemorrhagic fever with renal syndrome (hfrs) known as nephropathia epidemica (ne), which is triggered by the virus species puumala. its host is the bank vole (myodes glareolus). in the context of climate change, interest in the role of climatic factors for the disease has increased. a systematic review was conducted to investigate the association between climate va ... | 2015 | 25557350 |
| quantifying the past and future impact of climate on outbreak patterns of bank voles (myodes glareolus). | central european outbreak populations of the bank vole (myodes glareolus schreber) are known to cause damage in forestry and to transmit the most common type of hantavirus (puumala virus, puuv) to humans. a sound estimation of potential effects of future climate scenarios on population dynamics is a prerequisite for long-term management strategies. historic abundance time series were used to identify the key weather conditions associated with bank vole abundance, and were extrapolated to future ... | 2015 | 24889216 |
| complete genome and phylogeny of puumala hantavirus isolates circulating in france. | puumala virus (puuv) is the agent of nephropathia epidemica (ne), a mild form of hemorrhagic fever with renal syndrome (hfrs) in europe. ne incidence presents a high spatial variation throughout france, while the geographical distribution of the wild reservoir of puuv, the bank vole, is rather continuous. a missing piece of the puzzle is the current distribution and the genetic variation of puuv in france, which has been overlooked until now and remains poorly understood. during a population sur ... | 2015 | 26506370 |
| beech fructification and bank vole population dynamics--combined analyses of promoters of human puumala virus infections in germany. | the transmission of wildlife zoonoses to humans depends, amongst others, on complex interactions of host population ecology and pathogen dynamics within host populations. in europe, the puumala virus (puuv) causes nephropathia epidemica in humans. in this study we investigated complex interrelations within the epidemic system of puuv and its rodent host, the bank vole (myodes glareolus). we suggest that beech fructification and bank vole abundance are both decisive factors affecting human puuv i ... | 2015 | 26214509 |
| hokkaido genotype of puumala virus in the grey red-backed vole (myodes rufocanus) and northern red-backed vole (myodes rutilus) in siberia. | three species of myodes voles known to harbor hantaviruses include the bank vole (myodes glareolus), which serves as the reservoir host of puumala virus (puuv), the prototype arvicolid rodent-borne hantavirus causing hemorrhagic fever with renal syndrome (hfrs) in europe, and the grey red-backed vole (myodes rufocanus) and royal vole (myodes regulus) which carry two puuv-like hantaviruses, designated hokkaido virus (hokv) and muju virus (mujv), respectively. to ascertain the hantavirus harbored ... | 2015 | 26003760 |
| complete genome of a puumala virus strain from central europe. | puumala virus (puuv) is one of the predominant hantavirus species in europe causing mild to moderate cases of haemorrhagic fever with renal syndrome. parts of lower saxony in north-western germany are endemic for puuv infections. in this study, the complete puuv genome sequence of a bank vole-derived tissue sample from the 2007 outbreak was determined by a combined primer-walking and rna ligation strategy. the s, m and l genome segments were 1,828, 3,680 and 6,550 nucleotides in length, respecti ... | 2015 | 25543297 |
| bank voles show high seropositivity rates in a natural tbev focus in hungary. | rodents captured in a known tick-borne encephalitis virus (tbev) focus were serologically surveyed for 4 years, with 28 visits. the collected sera were analysed by virus neutralization test. bank vole (myodes glareolus) had a significantly higher incidence rate of antibodies to tbev (20.5%) than apodemus flavicollis (3.7%) and apodemus agrarius (4.6%). in all species, rates were higher in adults (6.8%) than in juveniles (1.7%). a higher incidence rate was observed in female a. flavicollis indivi ... | 2015 | 25549698 |
| bank vole prion protein as an apparently universal substrate for rt-quic-based detection and discrimination of prion strains. | prions propagate as multiple strains in a wide variety of mammalian species. the detection of all such strains by a single ultrasensitive assay such as real time quaking-induced conversion (rt-quic) would facilitate prion disease diagnosis, surveillance and research. previous studies have shown that bank voles, and transgenic mice expressing bank vole prion protein, are susceptible to most, if not all, types of prions. here we show that bacterially expressed recombinant bank vole prion protein ( ... | 2015 | 26086786 |
| identification of two novel members of the tentative genus wukipolyomavirus in wild rodents. | two novel polyomaviruses (pyvs) were identified in kidney and chest-cavity fluid samples of wild bank voles (myodes glareolus) and common voles (microtus arvalis) collected in germany. all cloned and sequenced genomes had the typical pyv genome organization, including putative open reading frames for early regulatory proteins large t antigen and small t antigen on one strand and for structural late proteins (vp1, vp2 and vp3) on the other strand. virus-like particles (vlps) were generated by yea ... | 2015 | 26474048 |
| further investigation of risk elements content in the bones of wild rodents from a polluted area in slovakia. | wild rodents are suitable for monitoring environmental pollution and exposure risk assessment for people living in contaminated areas. the content of selected risk elements in the femora of bank vole (myodes glareolus), yellow-necked mouse (apodemus flavicollis) and wood mouse (apodemus sylvaticus) was estimated from the kolíňany area of slovakia, which is characterized by a high degree of environmental pollution. the rodents were trapped in february 2011 using standard theriological methods. al ... | 2015 | 26303124 |
| occurrence and maintenance of hantavirus infections among rodent populations in their natural habitat--results of a field study from podkarpackie province, poland 2010-2012. | human cases of hantavirus infection have been reported annually in poland's podkarpackie province, since 2007. in 2014 the number of cases reported significantly increased prompting a rise in studies focusing on the infection. | 2015 | 26233088 |
| risk assessment of metals and pahs for receptor organisms in differently polluted areas in slovenia. | samples from receptor organisms (small mammals, passerine birds) and their food sources (herbaceous plants, leaves and fruits of wood plants, earthworms) were collected during 2011-2014 from the vicinity of a former lead smelter, from the vicinity of the largest slovenian thermal power plant, from along a state road and also from a reference area. the samples were then analysed to determine the degree of contamination with the metals (pb, cd, zn, hg, cu, mo) and with polycyclic aromatic hydrocar ... | 2015 | 26086372 |
| host preferences of immature dermacentor reticulatus (acari: ixodidae) in a forest habitat in germany. | dermacentor reticulatus is widespread throughout europe and is expanding its range in several european countries. it is associated with a number of different pathogens. its role in the transmission of disease to humans is currently small; however, it might play an important role in the maintenance of pathogens in enzootic cycles. the ecology of d. reticulatus, especially of the immatures, is not well known. in this study, ticks from small mammals, caught in a capture-mark-release study between m ... | 2015 | 25983104 |
| host-associated differences in morphometric traits of parasitic larvae hirsutiella zachvatkini (actinotrichida: trombiculidae). | examination of host-associated variation in the chigger mite hirsutiella zachvatkini (schluger) revealed morphological differences among larvae infesting sympatric hosts: apodemus agrarius, apodemus flavicollis and myodes glareolus. the analysis included 61 variables of larvae obtained from their gnathosoma, idiosoma and legs (measurements and counts). statistically significant differences were observed for metric characters of the legs as opposed to the scutum. in view of the conspecificity of ... | 2015 | 26002309 |
| sex differences in flea infections among rodent hosts: is there a male bias? | recognizing patterns of parasite distribution among wildlife hosts is of major importance due to growing risk of transmission of zoonotic diseases to humans. thus, sex-dependent parasite distribution in higher vertebrates is extensively studied, and males are often found more parasitized than females. male-biased parasitism may be the result of weaker immunocompetence of male hosts owing to the immunosuppressive effect of androgens. moreover, larger hosts (males) may demonstrate higher parasite ... | 2015 | 25410932 |
| analysis on population level reveals trappability of wild rodents is determined by previous trap occupant. | live trapping is central to the study of small mammals. thus, any bias needs to be understood and accounted for in subsequent analyses to ensure accurate population estimates. one rarely considered bias is the behavioural response of individuals to the trap, in particular the olfactory cues left behind by previous occupants (po). we used a data set of 8,115 trap nights spanning 17 separate trapping sessions between august 2002 and november 2013 in wytham woods, oxfordshire, uk to examine if the ... | 2015 | 26689683 |
| further characterisation of transmissible spongiform encephalopathy phenotypes after inoculation of cattle with two temporally separated sources of sheep scrapie from great britain. | the infectious agent responsible for the bovine spongiform encephalopathy (bse) epidemic in great britain is a transmissible spongiform encephalopathy (tse) strain with uniform properties but the origin of this strain remains unknown. based on the hypothesis that classical bse may have been caused by a tse strain present in sheep, cattle were inoculated intracerebrally with two different pools of brains from scrapie-affected sheep sourced prior to and during the bse epidemic to investigate resul ... | 2015 | 26205536 |
| the generalist tick ixodes ricinus and the specialist tick ixodes trianguliceps on shrews and rodents in a northern forest ecosystem--a role of body size even among small hosts. | understanding aggregation of ticks on hosts and attachment of life stages to different host species, are central components for understanding tick-borne disease epidemiology. the generalist tick, ixodes ricinus, is a well-known vector of lyme borrelioses, while the specialist tick, ixodes trianguliceps, feeding only on small mammals, may play a role in maintaining infection levels in hosts. in a northern forest in norway, we aimed to quantify the role of different small mammal species in feeding ... | 2015 | 26671686 |
| detection of lyme disease and q fever agents in wild rodents in central italy. | the maintenance of tick-borne disease agents in the environment strictly depends on the relationship between tick vectors and their hosts, which act as reservoirs for these pathogens. a pilot study aimed to investigate wild rodents as reservoirs for zoonotic tick-borne pathogens (borrelia burgdorferi sensu lato (s.l.), coxiella burnetii, francisella tularensis, and anaplasma phagocytophilum) was carried out in an area of gran sasso e monti della laga national park (abruzzi region, central italy) ... | 2015 | 26134933 |
