metabolic labelling of wild and laboratory subspecies of the trichostrongyle nematode heligmosomoides polygyrus.	the immunological, biochemical and taxonomic relationship between wild and laboratory subspecies of heligmosomoides polygyrus was studied by metabolically labelling parasite proteins with [35s]-methionine. much variability, both in content and synthesis of proteins was observed between the two subspecies. laboratory female worms had a higher protein content and incorporated more radioactive label into somatic proteins than their wild counterparts. incorporation of radioactivity into excretory/se ...	1994	7879381
rhythmicity of egg production by heligmosomoides polygyrus in wild wood mice, apodemus sylvaticus.	the rhythmicity of egg production by heligmosomoides polygyrus (nematoda) in wild caught wood mice (apodemus sylvaticus) was studied. faecal production followed a 24 h cycle, with peaks at 0400 h and troughs at 1300-1900 h. the patterns in eggs per gram of faeces (epg) and total eggs were similar to each other, though the former was more accentuated. both of these followed a 24 h cycle, with peaks coinciding with troughs in faecal production and vice versa. faecal weight was inversely correlated ...	1994	7930449
grahamella in small woodland mammals in the u.k.: isolation, prevalence and host specificity.	bacteria isolated from the blood of small woodland mammals were identified as members of the genus grahamella. the prevalence of grahamella infection among the 37 small mammals examined, detected by cultivation of blood samples, was 62%. this figure is somewhat higher than previous reports. further characterization of the isolates, based on restriction enzyme analysis of the 16s rrna gene, serological reactivity and dna hybridization studies, revealed three distinct grahamella species. one of th ...	1994	7944677
differential immune responses to borrelia burgdorferi in european wild rodent species influence spirochete transmission to ixodes ricinus l. (acari: ixodidae).	immune responses to borrelia burgdorferi and their influence on spirochete transmission to ixodes ricinus were analyzed in the natural european reservoir hosts; i.e., the mouse species apodemus flavicollis (yellow-necked mouse) and apodemus sylvaticus (wood mouse) and the vole species clethrionomys glareolus (bank vole), and, in addition, in the laboratory mouse strain nmri. naive and preimmunized rodents were infected either by artificially infected i. ricinus larvae or by intradermal injection ...	1994	7960113
density-dependent acquired resistance to ticks in natural hosts, independent of concurrent infection with babesia microti.	the question of whether the known immunosuppressive effects of babesia microti may disrupt the development of acquired resistance to its tick vector, ixodes trianguliceps, in natural rodent hosts (clethrionomys glareolus), and thus enhance the disease transmission potential, is addressed experimentally. the results show for the first time that natural hosts can acquire resistance to ticks; that this acquired resistance is manifested chiefly by a strongly density-dependent reduction in the percen ...	1994	8008455
a study of the ciliar tracheal epithelium on passerine birds and small mammals subjected to air pollution: ultrastructural study.	a study was made of the ciliar tracheal epithelium on passerine birds and small mammals subjected to nox, so2 emissions and particulates from a coal-fired power plant. the results were compared to those of a non-polluted area, very similar in vegetation, relief, and climatology. we studied carduelis carduelis (goldfinch), emberiza cia (rock bunting), parus major (great tit), turdus merula (blackbird), and apodemus sylvaticus (wood mouse). all animals were captured in the wild. we also used goldf ...	1994	8024317
different patterns of retinal cone topography in two genera of rodents, mus and apodemus.	recently, we have reported the peculiar topographic separation of shortwave- and middlewave-sensitive (s and m) cones in the retina of the common house mouse (mus musculus) and in a number of inbred laboratory mouse strains derived from the same species. in an attempt to follow the phylogeny of the complementary cone fields, we have investigated the retina of other mouse-like rodents. two monoclonal anti-visual pigment antibodies, os-2 and cos-1, specific to the s and m cones, respectively, have ...	1994	8187156
the woodmouse (apodemus sylvaticus) as a reservoir of tick-transmitted spirochetes (borrelia burgdorferi) in the netherlands.	in three widely separated locations in the netherlands, woodmice (apodemus sylvaticus) were trapped, examined for ticks and subjected to xenodiagnosis for the detection of tick-transmitted spirochetes (borrelia burgdorferi). during the spring and summer, an average of 2.4 ixodes larvae/mouse (n = 170) was observed, but the true numbers were probably greater. the numbers of nymphs could be determined more accurately and amounted to 0.46 nymphs/mouse. the percentage of mice that were infected with ...	1993	8219511
[serologic screening for the occurrence of leptospira antibodies in small wild mammals].	during the five years (1986-1990) free living small mammals were examined serologically for the presence of antibodies to leptospires. standardized techniques were used in the serological examinations (sebek, 1979). a total 4634 specimens representing 15 mammalian species were examined. during the studied period, higher occurrence of small terrestrial mammals was noticed in the years 1987-1988. in these years, 61% of specimens out of the total number of trapped animals were examined. the field m ...	1993	8236637
the arterial system of the wood mouse, apodemus sylvaticus: the pelvic region.	in this paper we describe the origin, arrangement and variations of the major pelvic arterial trunks in the wood mouse, apodemus sylvaticus. seventy-six specimens have been analyzed by injection of coloured latex solution through the left ventricle of the heart and subsequent dissection of the pelvic region. measurements of the origin of the major arterial trunks have been performed taking into account the number of anterior and posterior branches arising from its origin. only the values of the ...	1993	8238956
borrelia burgdorferi in a focus of lyme borreliosis: epizootiologic contribution of small mammals.	the contribution of woodmice (apodemus sylvaticus), yellow-necked mice (apodemus flavicollis) and bank voles (clethrionomys glareolus) was compared in a focus of lyme borreliosis in switzerland during a 7 months' study. all three species of mice and one species of shrews (sorex araneus) were shown parasitized by infected ixodes ricinus immatures. about 14% of larvae and 50% of nymphs collected on small mammals were infected with b. burgdorferi. spirochetes were isolated from blood of 3 woodmice ...	1993	8325567
effects of air pollution on passerine birds and small mammals.	the effects produced by emissions from coal-fired power plants, including mainly so2, nox and particulates, on natural populations and caged specimens of birds and small mammals were studied. the field-captured species used to evaluate these effects were passerine birds: parus major (coal tit) and emberiza cia (rock bunting), and the rodent apodemus sylvaticus (wood mouse). in parallel to this study on animals captured in the field, we used other animals, mus musculus (house mouse) and carduelis ...	1993	8466292
prevalence of encephalitozoon cuniculi antibodies in terrestrial mammals in iceland, 1986 to 1989.	antibodies to encephalitozoon cuniculi were found in wild arctic foxes (alopex lagopus), feral mink (mustela vison), wood mice (apodemus sylvaticus) and house mice (mus musculus) in iceland. animals with antibodies were found throughout the country. no lesions attributable to encephalitozoonosis were found in adult animals necropsied. however, one arctic fox cub with a neurological disorder had pathological and serological evidence of encephalitozoonosis.	1993	8487387
oral transmission of trypanosomes of the subgenus herpetosoma from small mammals.	the rodents microtus agrestis, clethrionomys glareolus, apodemus sylvaticus and white bk rats were given either a single intraperitoneal (i.p.) injection, an intragastric (i.g.) inoculation or an oral (p.o.) inoculation of the culture forms, including metacyclic trypomastigotes, of trypanosoma microti, t. evotomys, t. grosi and t. lewisi, respectively. similar levels of parasitaemia were produced by each of the three routes of infection, although the prepatent period was 3-5 days shorter in the ...	1995	8570586

[the genetic links and species affiliation of the field mouse (rodentia, muridae, sylvaemus) from the pamir-alai].	analysis of variation in 30 presumptive biochemical loci in sylvaemus sylvaticus pallipes from tadjikistan was carried out with reference to the geographically closely related species s. uralensis. the data obtained support the genetic identity of pallipes, on the one hand, and suggest a rather low level of genetic divergence (d'nei = 0.154, pfd = 13) from an ancestral taxon, on the other hand. analysis of genetic variation of diagnostic morphological features suggests that pallipes is the most ...	1996	8640110
behavioral and physiological effects of acute sublethal exposure to dimethoate on wood mice, apodemus sylvaticus.	the effects on behavior and cholinesterase (che) of an op pesticide, dimethoate, were examined in wood mice under laboratory conditions. mice were administered 0, 5, 15, or 50 mg/kg intraperitoneal dimethoate and their behavior was recorded in an open field for one hour. in a second experiment, using only the 0 and the 50 mg/kg dose, mice were subjected to 10-min open field tests repeated at various time intervals during a 24-h period. shortly after administration of dimethoate, there was a gene ...	1996	8687995
effects of air pollution on hematological and plasma parameters in apodemus sylvaticus and mus musculus.	the effects of atmospheric air pollution on some hematological and plasma parameters, activity, and food and water consumption in apodemus sylvaticus (wood mouse) and mus musculus (mouse) were studied. the studies were undertaken in the area of cercs (polluted area in spain), where there is a coal-fired power plant that emanates so2, nox, and particles, and the area of st. jaume de frontanyà (nonpolluted area), located 40 km from the area of cercs, with similar climatology, relief, and altitude, ...	1996	8688003
biogeography and taxonomy of apodemus sylvaticus (the woodmouse) in the tyrrhenian region: enzymatic variations and mitochondrial dna restriction pattern analysis.	in the western mediterranean area, the taxonomic status of the various forms of apodemus sylvaticus is quite unclear. moreover, though anthropogenic, the origins of the island populations remain unknown in geographical terms. in order to examine the level of genetic relatedness of insular and continental woodmice, 258 animals were caught in 24 localities distributed in belgium, france, mainland italy, sardinia, corsica and elba. electrophoresis of 33 allozymes and mtdna restriction fragments wer ...	1996	8728987
sexual dimorphism of gabaa receptor levels in subcortical brain regions of a woodland rodent (apodemus sylvaticus).	this is the first report of quantitative autoradiography results showing sex differences of gabaa receptor levels in brain regions of a wild rodent (wood mouse, apodemus sylvaticus) living in its natural habitat. the labeling of this gabaergic site with its specific high affinity radioligand [3h] muscimol provided a heterogeneous and dimorphic binding pattern in some of the neural centers. in the female, higher (> or = 50 < or = 65%) to moderately higher (< 50%) binding levels than in the male, ...	1996	8736580
seasonal incidence of ixodes ricinus ticks (acari:ixodidae) on rodents in western france.	data collected from a longitudinal survey carried out over 2 years on four farms in western france were used to assess the incidence and infestation of ixodes ricinus on rodents. once a month, on each farm, 25 sherman live traps were set in hedges bordering selected pastures. a total of 799 micromammals were examined, including apodemus sylvaticus, clethrionomys glareolus, microtus agrestis, microtus arvalis, and crocidura spp. larvae and nymphs of i. ricinus were found. small numbers of ixodes ...	1996	8771769
evidence of hantavirus in wild rodents in northern ireland.	a survey of evidence of rodent hantavirus infection in county down, northern ireland was carried out by using immunofluorescence to detect virus antigen and antibody. antibodies to hantavirus (r22 strain of seoul virus and hantaan 76-118) were found in 11/51 (21.6%) brown rats (rattus norvegicus), 1/31 (3.2%) field mice (apodemus sylvaticus) and 17/59 (28.8%) house mice (mus domesticus). seven rodents had evidence of hantavirus antigen in lung tissues. antibody positive animals were significantl ...	1996	8870634
distribution of mossy fibres in the hippocampus of two closely related species of mice.	the relative volumes of different parts of the mossy fibre projection system- the suprapyramidal mossy fibres (sp-mf) and the intra- and infrapyramidal mossy fibres (iip-mf)- were determined in the hippocampi of apodemus sylvaticus and a. flavicollis. the mean contribution of the iip-mf to the mossy fibre system differed significantly between the two species. an increased relative size of the iip-mf as compared to the sp-mf in a. sylvaticus was linked with a reduction in the relative size of the ...	1996	8891293
behavioral effects of acute sublethal exposure to dimethoate on wood mice, apodemus sylvaticus: ii--field studies on radio-tagged mice in a cereal ecosystem.	the effects of direct exposure to an organophosphate (op) pesticide, dimethoate, were examined in free-living wood mice, apodemus sylvaticus, in a wheat field. male mice were radio-tagged at night and followed during 2-3-d periods, before and after an intraperitoneal injection of 50 mg/kg dimethoate which previous laboratory studies had demonstrated causes a maximum depression in brain acetylcholinesterase (ache) activity of 75% relative to non-exposed mice. in subsequent weeks, survival was est ...	1996	8975827
dimorphic distribution of the two main gaba(a) binding sites in cortical and limbic areas of a rodent living in natural environmental conditions.	labeling of the two more important gamma-aminobutyric acida (gaba(a)) supramolecular sites with [3h] muscimol (gaba(a)) and [3h] flunitrazepam (benzodiazepine) provided saturable, stable, and dimorphic binding activities in cortical and limbic regions of the wood mouse apodemus sylvaticus. of the cortical layers, which contained the highest [3h] muscimol binding levels, only the female lamina v supplied a greater (51%; p <0.01) receptor density than in the male. areas of the limbic system instea ...	1997	9087523
seasonal variation in the resting metabolic rate of male wood mice apodemus sylvaticus from two contrasting habitats 15 km apart.	diurnal and nocturnal resting metabolic rates of winter- and summer-acclimatized adult male wood mice apodemus sylvaticus from two adjacent populations, 15 km apart, were measured. one population lived in deciduous woodland, and experienced a narrower daily range of temperatures than the second population, which inhabited maritime sand-dunes. ambient temperature and body mass had significant effects on the resting metabolism of mice, excluding winter-acclimatized sand-dune animals where only tem ...	1997	9151433
the prevalence of cryptosporidium parvum and c. muris in mus domesticus, apodemus sylvaticus and clethrionomys glareolus in an agricultural system.	wild mice and voles were tested for cryptosporidium during a 2-year survey at an agricultural site in warwickshire, united kingdom. c. parvum and c. muris, the two cryptosporidial species known to infect mammals, were detected. prevalence figures of 22%, 21% and 13% noted for c. parvum for mus domesticus, apodemus sylvaticus and clethrionomys glareolus, respectively, were higher than those recorded for c. muris at 10%, 6% and 2%. c. parvum causes the sometimes severe diarrhoeal disease cryptospo ...	1997	9197396
the effects of host population density on the epidemiology of the trichostrongyle nematode heligmosomoides polygyrus.	the present study considers the effect mouse population density on the fecundity, expressed as daily egg output per gram of faeces, and infectivity of the trichostrongyle nematode. heligmosomoides polygyrus and in the field mouse (apodemus sylvaticus) and h. p. bakeri in laboratory mouse (cd1). the higher host density resulted in an increased fecundity of h. polygyrus compared with medium and lower host densities. however, the number of h. p. polygyrus and h. p. bakeri recovered 30 days post-inf ...	1997	9257998
small mammals from sima de los huesos.	a small collection of rodents from sima de los huesos helps to clarify the stratigraphic position of this famous human locality. the presence of allocricetus bursae and pliomys lenki relictus and the size of a. bursae, apodemus sylvaticus and eliomys quercinus suggest a middle pleistocene age (saalian) to the clays where humans have been found.	1997	9300341
daily variations in the response of wood mice apodemus sylvaticus to noradrenaline	non-shivering thermogenesis (nst) is an important mechanism for heat production in many small rodent species. daily rhythms of body (rectal) temperature (tb) reflect the relationship between heat production and heat dissipation. the roles of photoperiod and the time of day at which nst is measured were studied in wood mice apodemus sylvaticus. mice of both sexes (n=18) were acclimated to two different photoperiod regimes (16 h:8 h l:d and 8 h:16 h l:d) at a constant ambient temperature (ta) of 2 ...	1995	9318261
spontaneous and radiation-induced micronuclei in erythrocytes from four species of wild rodents: a comparison with cba mice.	almost 100 animals of 4 different species of small wild rodents (bank vole, clethrionomys glareolus; field vole, microtus agrestis; yellow-necked mouse, apodemus flavicollis; and wood mouse, apodemus sylvaticus) were trapped in central sweden and used in experiments to determine the spontaneous and radiation-induced frequencies of polychromatic (fmpce) and normochromatic erythrocytes (fmnce) from bone marrow (bm) and peripheral blood (pb) using flow cytometric analysis. the results were compared ...	1997	9357562
apparent absorption efficiency and gut morphometry of wood mice, apodemus sylvaticus, from two distinct populations with different diets.	interpopulation variation in the diet of the wood mouse, apodemus sylvaticus, is well documented. in this study, we examined the gut morphology and apparent absorption efficiencies of two populations of wood mice whose diet in the field was known to differ. one population inhabited sand dunes, where food availability was relatively low and the diet was dominated by invertebrates. the other population lived in deciduous woodland, with greater food availability and a diet consisting primarily of s ...	1997	9361134
the effect of cowpox virus infection on fecundity in bank voles and wood mice.	although epidemic infectious diseases are a recognized cause of changes in host population dynamics, there is little direct evidence for the effect of endemic infections on populations. cowpox virus is an orthopoxvirus which is endemic in bank voles (clethrionomys glareolus), wood mice (apodemus sylvaticus) and field voles (microtus agrestis) in great britain. it does not cause obvious signs of disease nor does it affect survival, but in this study we demonstrate experimentally that it can reduc ...	1997	9364786
origin of an insular population of the wood mouse based on parasitological evidence.	parasitological data were used to test the hypothesis that the wood mouse (apodemus sylvaticus) population of fair isle, shetland, originated from the british isles rather than scandinavia, as is usually argued. this study was based on the assumption that the mice were likely to share most of their parasite fauna with conspecifics from their ancestral home. the ecto- and endo-parasites of wood mice on fair isle between 18 june to 10 july 1987 and 17 to 26 august 1991 were identified and compared ...	1998	9476237
serosurvey for orthopoxviruses in rodents and shrews from norway.	two hundred and twenty one blood samples representing eight different rodent species and the common shrew (sorex araneus), collected in norway between 1993 and 1995, were examined for anti-orthopoxvirus antibodies by a competition enzyme linked imunnosorbent assay (elisa) and, when possible, an indirect immunofluorescence assay. the serological results indicated that the bank vole (clethrionomys glareolus), woodmouse (apodemus sylvaticus) and norway lemming (lemmus lemmus) may be reservoir speci ...	1998	9577770
vertical transmission of toxoplasma gondii from chronically infected house (mus musculus) and field (apodemus sylvaticus) mice determined by polymerase chain reaction.	captive-bred mus musculus (house mice) and apodemus sylvaticus (field mice) were each infected with 50 oocysts of toxoplasma gondii m1 strain per os and infection in them and their offspring was assessed by polymerase chain reaction (pcr) amplification of the t. gondii b1 gene in brain tissue and by serology, using the modified agglutination test (mat). the chronically infected female a. sylvaticus (n = 10) and m. musculus (n = 23) were mated at least 6 weeks after infection (and subsequently to ...	1998	9585931
infectivity of cryptosporidium muris isolated from cattle.	the infectivity of a bovine isolate of cryptosporidium muris for various animals was studied by transmission experiments. neonatal balb/c mice, adult balb/c mice, scid mice, common voles (microtus arvalis), bank voles (clethrionomys glareolus), common field mice (apodemus sylvaticus), mongolian gerbils (meriones unguiculatus), desert gerbils (gerbilus gerbilus), guinea pigs, rats, rabbits and goats were used to test the infectivity of this isolate. among these host species, only mongolian gerbil ...	1998	9615952
naturally occurring orthopoxviruses: potential for recombination with vaccine vectors.	orthopoxviruses are being increasingly used as live recombinant vectors for vaccination against numerous infectious diseases in humans, domestic animals, and wildlife. for risk assessments and surveillance, information about the occurrence, distribution and ecology of orthopoxviruses in western europe is important but has mainly been based on serological investigations. we have examined kidneys, lungs, spleens, and livers of norwegian small rodents and common shrews (sorex araneus) for the prese ...	1998	9705389
selective isolation of pseudomonas stutzeri from vertebrate faeces on rambach agar.	faecal samples collected from 308 wild birds of 25 species and 19 rodents of 3 species in south moravia (czechland) were pre-incubated in müller-kauffmann tetrathionate broth at 42 degrees c for 24 h and then streaked onto rambach agar plates which were incubated at 37 degrees c for 48 h. seventeen out of 22 isolates forming orange-red colonies on rambach agar were identified as pseudomonas stutzeri, the rest as pseudomonas sp. and alcaligenes sp. the colonies of p. stutzeri were either dry, wri ...	1998	9861678
[histological analysis of the testis of apodemus sylvaticus and clethrionomys rutilus living in radioactively contaminated areas].	we made a histological analysis of testis in apodemus sylvaticus and clethrionomys rutilus inhabiting a contaminated area of the east ural radioactive trace (eurt). it showed that in the control these species different in the total number of cells of spermatogenic epithelium and in testis indices which were determined by interspecific differences. concentration of 137cs and 90sr in clethrionomys rutilus from the sampling plot was correspondingly 1.5 and 6.1 times higher than in the control, in a ...	2016	9889775
on the mtdna restriction patterns variation of the iberian wood mouse (apodemus sylvaticus). comparison with other west mediterranean populations.	in previous studies, the presence of three main lineages of wood mice mtdna was described in western europe: a first one distributed from the pyrenees to scandinavia. a thyrrenian one occurring in peninsular italy, elba, corsica and sardinia and a third one restricted to sicily and marettimo. do the iberian wood mice belong to one of these lineages? in order to answer this question, animals were trapped all over the iberian peninsula (11 sites) as well as in three of the balearic islands. compar ...	1998	10319716
helminth infections in apodemus sylvaticus in southern england: interactive effects of host age, sex and year on the prevalence and abundance of infections.	helminth parasites were studied in the wood mouse, apodemus sylvaticus, in southern england in september of each of four successive years (1994-1997). nine species of helminths were recorded: five nematodes (heligmosomoides polygyrus, syphacia stroma, pelodera strongyloides, trichuris muris, capillaria murissylvatici), two cestodes (microsomacanthus crenata, taenia taeniaeformis) and two trematodes (corrigia vitta, brachylaemus recurvum). in total, 134 mice were examined and 91.8% carried at lea ...	1999	10431369

radionuclide behaviour and transport in a coniferous woodland ecosystem: vegetation, invertebrates and wood mice, apodemus sylvaticus.	activity concentrations of radionuclides (134cs, 137cs, 238pu, 239 + 240pu and 241am) were measured in vegetation, invertebrates and wood mice, apodemus sylvaticus, collected in lady wood, a coniferous woodland in the vicinity of the british nuclear fuels reprocessing plant at sellafield, cumbria, uk. vegetation was of low diversity and biomass with activity concentrations ranging from 1 to 5 bq kg-1 (134cs), 0.3-0.5 bq kg-1 (238pu), 0.8-8 bq kg-1 (239 + 240pu), and 0.6-16 bq kg-1 (241am), dry w ...	1999	10570837
borrelia burgdorferi sensu lato in ixodes ricinus ticks and rodents in a recreational park in south-western ireland.	ixodes ricinus ticks infected with borrelia burgdorferi sensu lato were numerous on the edges of paths and roads in a recreational park in south-western ireland. the abundance of ticks at different sites was related to the presence of deer, but a negative relationship was shown between tick abundance and tick infection rates. this is thought to be due to the deposition of large numbers of uninfected ticks by deer, which are apparently not good reservoir hosts of b. burgdorferi s.l. blood meal an ...	1999	10581711
transmission dynamics of a zoonotic pathogen within and between wildlife host species.	the transmission dynamics of the cowpox virus infection have been quantified in two mixed populations of bank voles (clethrionomys glareolus) and wood mice (apodemus sylvaticus), through analyses of detailed time-series of the numbers of susceptible, infectious and newly infected individuals. the cowpox virus is a zoonosis which circulates in these rodent hosts and has been shown to have an adverse effect on reproductive output. the transmission dynamics within species is best described as frequ ...	1999	10584336
aspects of mammalian spermatogenesis: electrophoretical analysis of protamines in mammalian species.	protamines are small, highly basic proteins that replace histones and testicular basic proteins during the development of mature spermatozoa, spermatogenesis. in mammals, extensive disulfide crosslinking of protamines result in the formation of a compact chromatin structure devoid of transcriptional activity. as determined by isolation and electrophoresis of protamines, only one protamine has been detected in the mature spermatozoa of most mammalian species. however, in the spermatozoa of the mo ...	1999	10597046
pcr detection of granulocytic ehrlichiae in ixodes ricinus ticks and wild small mammals in western switzerland.	the presence of granulocytic ehrlichiae was demonstrated by pcr in ixodes ricinus ticks and wild small mammals in switzerland in two areas of endemicity for bovine ehrlichiosis. six ticks (three females and three nymphs) (1.4%) of 417 i. ricinus ticks collected by flagging vegetation contained ehrlichial dna. a total of 201 small mammals from five species, wood mouse (apodemus sylvaticus), yellow-necked mouse (apodemus flavicollis), earth vole (pitymys subterraneus), bank vole (clethrionomys gla ...	2000	10698987
environmental effects of radionuclides--observations on natural ecosystems.	to better quantify risk to non-human species from exposure to environmental radioactivity, understanding of the behaviour of radionuclides in the biosphere needs to be increased. this study outlines current thinking on ecological risk assessment (era) methodology and applies the indicator species or critical groups approach to biota inhabiting a semi-natural coniferous woodland contaminated with the radionuclides 137cs, 238pu, 239+240pu and 241am. the majority of these radionuclides originate fr ...	2000	10750953
spatial and temporal dynamics of puumala hantavirus infection in red bank vole (clethrionomys glareolus) populations in belgium.	dynamics of hantavirus infection and population densities in rodents were investigated from 1996 to 1999 in southern belgium. evidence of puumala infection was restricted to clethrionomys glareolus. although the serotype was not determined, antibodies against hantavirus were also found in eight apodemus sylvaticus. in fall 1996, the seroprevalence in c. glareolus was high (20.1%, 37 of 184) and the infection was widely distributed in the area studied whereas a focal occurrence of positive rodent ...	2000	10773322
on the morphology of heligmosomoides polygyrus (nematoda-trichostrongylidae) from the field mouse apodemus sylvaticus.	the morphology of the trichostrongylid nematode heligmosomoides polygyrus is described by light and scanning electron microscopy. in light microscope, the present material agrees with the original description given by baylis (1926), except for the addition of more details about the structure of the genital cone and the synlophe. the scanning electron microscopy of the present nematode revealed that the oral opening of the immature worm (l5) is rounded and its cuticular surface is loosely attache ...	2000	10786017
population biology of eimeria (protozoa: apicomplexa) in apodemus sylvaticus: a capture/recapture study.	the first long-term (27 month) survey of single species of eimeria occurring in a population of apodemus sylvaticus in the uk showed that eimeria apionodes, e. hungaryensis and e. uptoni occurred throughout the period whilst e. sp. e. was only found during 4 months. in first-captured animals, overall prevalence of eimeria spp. was 73%: a figure higher than previously published, but possibly an underestimate. multiple infections (2 or 3 species) occurred in 34% of first-capture infected animals, ...	2000	10811276
seasonal and site specific variation in the component community structure of intestinal helminths in apodemus sylvaticus from three contrasting habitats in south-east england.	seasonal fluctuations in the prevalence and abundance of infection with intestinal helminths were studied in apodemus sylvaticus (wood mouse, n = 399), from three contrasting habitats in southern england, to test the hypothesis that both intrinsic (host sex, age) and extrinsic (season, site) factors influence parasite species richness and abundance. five species of helminths were recovered but only one of these (capillaria murissylvatici) was site-specific (dungeness). total species richness was ...	2000	10831048

silent ribosomal cistrons are located at the pairing segment of the postreductional sex chromosomes of apodemus sylvaticus (rodentia, muridae).	we analysed the karyotype of the rodent species apodemus sylvaticus by g- and c-banding, ag-nor-staining and in situ hybridization, with special attention to the sex chromosomes. nor-bearing chromosome pairs were identified with simultaneous staining of g bands and nors. in situ hybridization with an rdna probe revealed the presence of silent ribosomal cistrons in both sex chromosomes. studies of meiosis demonstrated that these inactive ribosomal cistrons are located in the pairing segment, whic ...	2001	11380657
orientation and movement patterns of the wood mouse (apodemus sylvaticus) in its home range are not altered by olfactory or visual deprivation.	movements of wood mice (apodemus sylvaticus) were recorded in the field in natural (non-deprived) and in vision- or olfaction-deprived conditions. both visually and olfactorily deprived animals were able to efficiently orient themselves within their home ranges. there were no, or only nearly, significant differences between the movement characteristics of non-deprived and deprived animals. moreover, movements of deprived animals were significantly more concentrated than expected in familiar plac ...	2001	11401204
morphological and genetic differentiation of rodentolepis straminea (goeze, 1752) and rodentolepis microstoma (dujardin, 1845) (hymenolepididae).	the two related species, rodentolepis straminea (goeze, 1782) and rodentolepis microstoma (dujardin, 1845) (cestoda, hymenolepididae), both parasites of rodents, were compared morphologically and electrophoretically. adult worms were isolated from three wild rodent species of the family muridae (apodemus flavicollis, apodemus sylvaticus, and mus musculus) from three different sites in spain and france. although these two species were strikingly similar in morphological appearance, some of the mo ...	2001	11411941
demonstration of chymotryptic and tryptic activities in mast cells of rodents: comparison of 17 species of the family muridae.	on the basis of studies in laboratory rats, mast cells were originally classified into two subgroups, namely, mucosal mast cells (mmcs), which contained chymase, and connective tissue mast cells (ctmcs), which contained both tryptase and chymase. this classification has been applied to other animal species, despite the fact that the mmcs and ctmcs of such species sometimes consist of mixed populations of mast cells in terms of tryptase and chymase constitution. this report describes the protease ...	2001	11437520
high-resolution magic angle spinning 1h-nmr spectroscopy studies on the renal biochemistry in the bank vole (clethrionomys glareolus) and the effects of arsenic (as3+) toxicity.	1. high-resolution magic angle spinning (mas) 1h-nmr spectroscopy was used to study renal metabolism and the toxicity of as3+, a common environmental contaminant, in the bank vole (clethrionomys glareolus), a wild species of rodent. 2. following a 14-day exposure to an environmentally relevant dose of as2o3 (28 mg kg(-1) feed), voles displayed tissue damage at autopsy. mas 1h spectra indicated abnormal lipid profiles in these samples. 3. tissue necrosis was also evident from measurements of the ...	2001	11513249
[hantavirus infection epidemiology in belgium].	in europe, puumala (puu) is a hantavirus responsible for a human disease called nephropathia epidemica and its natural reservoir is the red bank vole, (clethrionomys glareolus). although the population densities and the prevalence rates of infection were high in red bank voles in southern belgium during the 1996 and 1999 epidemic years, the percentages of infected rodents were low in 1997 and 1998, when only a few positive sites were found. antibodies against puu virus were mainly detected in th ...	2001	11697188
the importance of the gut and its contents in prey as a source of cadmium to predators.	many mammalian and avian predators consume the whole carcass of their small mammal prey. thus, the contaminant load of the gut and its contents may be of toxicological significance, but pollutant loads in the gut of prey species are often not measured and their role in food-chain transfer of contaminants is largely unquantified. we investigated the importance of the gut and its contents in prey as a source of cadmium (cd) to predators by measuring the cd concentrations in the guts (including con ...	2002	11804064
host specificity of trypanosoma (herpetosoma) species: evidence that bank voles (clethrionomys glareolus) carry only one t. (h.) evotomys 18s rrna genotype but wood mice (apodemus sylvaticus) carry at least two polyphyletic parasites.	the strongest evidence for host specificity of mammalian trypanosomes comes from parasites of the subgenus trypanosoma (herpetosoma). laboratory studies have shown that t. (herpetosoma) species will not infect an alternative host. however, this has not been demonstrated in wild populations. we screened 560 bank voles (clethrionomys glareolus) and 148 wood mice (apodemus sylvaticus) for trypanosomes by pcr amplification of the 18s rrna gene. in total, 109 (19%) bank voles and 12 (8%) wood mice we ...	2002	11860034
influence of age, sex, and sexual activity on trace element levels and antioxidant enzyme activities in field mice (apodemus sylyaticus and mus spretus).	the influence of age, gender and sexual activity on both hepatic levels of some trace elements (fe, cu, zn, mn, se) and the activities of glutathione-s-transferase (gst) and superoxide dismutase (sod) was investigated in wood mice (apodemus sylvaticus) and algerian mice (mus spretus). animals were taken from a riverside community of an unpolluted area of central portugal. adult a. sylvaticus presented the highest hepatic mean concentrations of cu and mn, whereas adult m. spretus had the highest ...	2002	11934247
excretion of vancomycin-resistant enterococci by wild mammals.	a survey of fecal samples found enterococcal excretion in 82% of 388 bank voles (clethrionomys glareolus), 92% of 131 woodmice (apodemus sylvaticus), and 75% of 165 badgers (meles meles). vancomycin-resistant enterococci, all enterococcus faecium of vana genotype, were excreted by 4.6% of the woodmice and 1.2% of the badgers, but by none of the bank voles.	2002	12023924

determination of trichuris muris from murid hosts and t. arvicolae (nematoda) from arvicolid rodents by amplification and sequentiation of the its1-5.8s-its2 segment of the ribosomal dna.	trichuris muris has been isolated from murid hosts ( apodemus sylvaticus and mus musculus) and trichuris arvicolae from arvicolid rodents in barcelona, spain. genomic dna was isolated and the its1-5.8s-its2 segment from the ribosomal dna (rdna) was amplified and sequenced using polymerase chain reaction techniques. the its2 of both populations isolated from apodemus and mus was 382 nucleotides in length and had a gc content of about 60.73%, while the its2 of t. arvicolae was 442 nucleotides in l ...	2002	12107482
exceptional sperm cooperation in the wood mouse.	spermatozoa from a single male will compete for fertilization of ova with spermatozoa from another male when present in the female reproductive tract at the same time. close genetic relatedness predisposes individuals towards altruism, and as haploid germ cells of an ejaculate will have genotypic similarity of 50%, it is predicted that spermatozoa may display cooperation and altruism to gain an advantage when inter-male sperm competition is intense. we report here the probable altruistic behavio ...	2002	12110888
mycobacterium microti infection (vole tuberculosis) in wild rodent populations.	mycobacterium microti (vole tuberculosis) infections in small wild mammals were first described more than 60 years ago in several populations in great britain. few studies of vole tuberculosis have been undertaken since then, and little is known about the relationship between m. microti isolates originating from different populations or at different times or of the prevalence of this infection in wild rodent populations, despite human cases of m. microti infections being increasingly reported. i ...	2002	12202566
modeling cadmium dynamics in the guts and tissues of small mammals: dose implications for predators.	predators that consume contaminated small-mammal prey are exposed to pollutants present in both the prey tissues and the prey gut. however, the contribution of the prey gut and its contents to the contaminant intake of the predator is often ignored. this study developed a two-compartment model of the dynamics of cd in a model prey species, the wood mouse (apodemus sylvaticus). the results from the cd dynamics model were used to calibrate a revised predator dose estimation methodology that accoun ...	2002	12389931

mitochondrial phylogeography of the woodmouse (apodemus sylvaticus) in the western palearctic region.	we sequenced 965 base pairs of the mitochondrial dna cytochrome b from 102 woodmice (apodemus sylvaticus) collected from 40 european localities. the aims of the study were to answer the following questions. (i) did the mediterranean peninsulas play a role as refuge for woodmice? (ii) is genetic variability of a. sylvaticus higher in the mediterranean region compared with northern europe? (iii) are the patterns of the postglacial colonization of europe by woodmice similar to those presently recog ...	2003	12675824
way-marking behaviour: an aid to spatial navigation in the wood mouse (apodemus sylvaticus).	during their movements in the wild, wood mice (apodemus sylvaticus) distribute small objects, such as leaves or twigs, which are often visually conspicuous. our experiments demonstrate that these marks serve as points of reference during exploration. way-marking, as we call it, may diminish the likelihood of losing an "interesting" location, perhaps following disturbance by, for example, a predator or conspecific. way-marks, being readily portable, may be a less confusing method of marking ephem ...	2003	12697070
exposure of small mammals, in particular the wood mouse apodemus sylvaticus, to pesticide seed treatments.	field exposure of small mammals to fungicide-treated wheat seed was investigated over three weeks following drilling on fields near york, united kingdom. seed consumption by small mammals trapped on and immediately adjacent to the drilled fields was quantified by measuring the amount of seed in the stomach. in addition, exposure to one seed-treatment, fluquinconazole, was quantified by measuring residues of the fungicide in the stomach, liver, and intestine. the wood mouse, apodemus sylvaticus, ...	2003	12729225
a comparison of the structure of helminth communities in the woodmouse, apodemus sylvaticus, on islands of the western mediterranean and continental europe.	we investigated the pattern of helminth species diversity in woodmouse, apodemus sylvaticus, on western mediterranean islands. we first performed a survey of the helminth fauna of a. sylvaticus in sicily. despite the small sampling effort, parasite species richness in sicily is large in comparison with parasite species richness on other mediterranean islands. we tested the nestedness of helminth parasite species from a number of mediterranean localities using data compiled from epidemiological s ...	2003	12743806
rickettsia typhi infection in wild rodents from central spain.	when sera from 218 rodents captured in two provinces of central spain were tested, by indirect immunofluorescence, for antibodies to rickettsia typhi, 46 (21.1%) were found to be positive, at titres between 1:20 and 1:320. the seropositives included rodents of each of the five species collected: mus musculus, mus spretus, apodemus sylvaticus, rattus rattus and rattus norvegicus. rickettsia typhi infection appears to be common and widespread among the rodents of central spain.	2003	12831526
