| [relation between characteristics of the small mammal population and occurrence of leptospira antibodies]. | five rodent species (apodemus flavicollis, a. agrarius, a. microps, clethrionomys glareolus and microtus arvalis) were examined serologically for presence of antibodies to leptospira. small mammals were caught in several areas of eastern slovakia, an important part of host material coming from east slovakian lowland (45.7%), south part of kosice basin (26.5%) and slovak carst (10.1%). serological examinations were used by kmety and bakoss (1978), the sexual condition of rodents were ascertained ... | 1997 | 9481926 |
| [hantavirus infection: a "new" exotic zoonosis among us]. | hantavirus disease is a recently recognized zoonosis. the main vectors are infected but healthy wild rodents or laboratory rats. transmission to man occurs via inhalation of aerosolised excretions. kidneys or lungs are the target organs during the disease, but a systemic affection with multi-organ involvement is possible, and can be fatal. to date, at least 16 different serotypes of hantavirus have been characterized, 8 of them being of clinical importance. each serotype has its own rodent vecto ... | 1996 | 9156672 |
| distribution and genetic heterogeneity of puumala virus in sweden. | small mammals trapped in sweden were analysed for specific antibody responses against three hantavirus serotypes and for the presence of viral antigen. to determine the genetic identity of viral rna in lungs of seropositive bank voles (clethrionomys glareolus), polymerase chain reactions and subsequent partial sequencing of both the m and s segments were employed. the sequences obtained were all identified as puumala (puu) virus, with a high degree of heterogeneity between the different geograph ... | 1996 | 8887490 |
| variability of sex ratio, mating probability and egg production in an intestinal nematode in its fluctuating host population. | in dioecious parasites, the chances of co-occurring with the opposite sex depend on the sex ratio, abundance and distribution pattern of parasites within the host population. theory suggests that if the abundance and degree of aggregation are very low, mating probability may decrease so much that the parasite population is vulnerable to extinction. our aim is to determine the factors affecting the mating probability and egg production in heligmosomum mixtum (heligmosomidae), an intestinal nemato ... | 1996 | 8894767 |
| [the topographic zoning of natural hfrs foci in russia]. | using large selections the unified system of landscape districting of hfrs natural foci with allocation of special geo-botanical provinces has been developed. this permits to avoid various deviations were found to appear during association of epizootiological and epidemiological indexes of separate towns and rural districts when estimating regional parameters. adequacy of the offered system in confirmed by five-fold increase of the correlation between hfrs epizootiological parameters and antibod ... | 1996 | 8926930 |
| [the isolation of borrelia from the tick ixodes trianguliceps (ixodidae) and the possible significance of this species in the epizootiology of ixodid tick-borne borrelioses]. | ixodes trianguliceps is a common tick species of the eurasian forest zone. these ticks live probably in natural foci of ixodid tick-borne borrelioses (itbb) from western europe to transbaikalia, but their role in circulation of corresponding pathogens remains unclear. this study was performed in a natural itbb focus located in the perm region of russia (near the urals), where borrelia garinii and b. afzelii circulate and i. persulcatus serves as their main vector. in july-august of 1994, 296 sma ... | 1996 | 8975209 |
| safety study of the sag2 rabies virus mutant in several non-target species with a view to its future use for the immunization of foxes in europe. | the safety of the sag2 virus, a low virulence mutant of the sad strain, was investigated in ten species of mammals and seven species of birds liable to consume vaccine baits. these species are the western hedgehog (erinaceus europaeus), the meadow vole (microtus arvalis), the bank vole (clethrionomys glareolus), the water vole (arvicola terrestris), the field mouse (apodemus flavicollis or a. sylvaticus), the norway rat (rattus norvegicus), the european badger (meles meles), the domestic ferret ... | 1996 | 9014291 |
| [leptospira antibodies in small mammals in eastern slovakia]. | during the five years (1991-1995) mostly free living small mammals were examined serologically for the presence of antibodies to leptospira. serological examinations were used by kmety and bakoss (1978). altogether, 2493 individuals of 22 species were examined, an important part of host material (69.6%) was caught in two lowland areas which are intensively cultivated landscapes (east slovakian lowland and kosická kotlina basin). the remaining material comes from submontane areas with less agricu ... | 1996 | 9045500 |
| characterization of puumala virus nucleocapsid protein: identification of b-cell epitopes and domains involved in protective immunity. | b-cell epitopes in the nucleocapsid protein (n) of puumala (puu) virus were investigated by use of truncated recombinant proteins and overlapping peptides. six of seven epitopes, recognized by bank vole monoclonal antibodies, were localized within the amino-terminal region of the protein (aa 1-79). polyclonal antibodies from wild-trapped or experimentally infected bank voles identified epitopes located over the entire protein. antibody end-point titers to different n fragments indicated that the ... | 1996 | 8607269 |
| hantavirus antigen detection using human serum immunoglobulin m as the capturing antibody in an enzyme-linked immunosorbent assay. | an enzyme-linked immunosorbent assay (elisa) was developed to detect different hantavirus antigens in cell culture; i.e. puumala (puu), hantaan (htn), and dobrava (dob) viruses. the assay was based on binding human serum immunoglobulin m (igm) antibodies to the solid phase by use of goat anti-igm antibodies. the captured igm antibodies were present in the acute phase serum from two patients: one infected in sweden and the other in bosnia. antigens being bound to the solid phase by the human anti ... | 1996 | 8615449 |
| importance of localized skin infection in tick-borne encephalitis virus transmission. | arboviruses are transmitted to vertebrates by the "bite" of infected arthropods. events at the site of virus deposition are largely unknown despite increasing evidence that blood-sucking arthropods immunomodulate their skin site of feeding. this question is particularly relevant for ixodid ticks that feed for several days. to examine events under conditions mimicking tick-borne encephalitis (tbe) virus transmission in nature (i.e., infected and uninfected ixodes ricinus ticks feeding on the same ... | 1996 | 8638401 |
| serological survey for orthopoxvirus infection of wild mammals in areas where a recombinant rabies virus is used to vaccinate foxes. | several fox vaccination campaigns against rabies have been undertaken in belgium by using a vaccinia-rabies recombinant virus distributed in baits in the field. however, foxes and other wild animals that may ingest the baits could be infected at the same time by another orthopoxvirus, such as cowpox virus, which circulates in wildlife. recombination between the two viruses could therefore occur. a serological survey for antibodies to orthopoxvirus, and particularly to cowpox virus, was undertake ... | 1996 | 8734505 |
| immunocytochemical demonstration of androgen receptors in leydig cells of the bank vole (clethrionomys glareolus, schreber): an in vitro study. | androgen receptors of the bank vole leydig cells in vitro were immunostained using a polyclonal antibody against androgen receptors followed by streptavidine-peroxidase complex or rhodamine-labelled goat anti-rabbit igg visualization. the immunocytochemical studies revealed localization of androgen receptors in the whole cytoplasm or in the perinuclear area of the cells. addition of dehydroepiandrosterone into the culture medium resulted in nuclear localization of the androgen receptors. long (1 ... | 1996 | 8739300 |
| a comparison of phase contrast microscopy and an immunofluorescence test for the detection of giardia spp. in faecal specimens from cattle and wild rodents. | as part of a study on the presence of giardia cysts in water, a commercial direct immunofluorescence (dif) test for the cysts was evaluated and compared to phase contrast microscopy. forty faecal samples were collected from cattle; 31 contained giardia. all 31 samples were positive by dif whereas only 17 were detected by microscopy. the detected giardia cysts were identified as belonging to the g. duodenalis group. 216 faecal samples were collected from wild rodents (apodemus flavicollis, a. syl ... | 1996 | 8758066 |
| 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 |
| vector-borne viral diseases in sweden--a short review. | ockelbo disease, caused by a sindbis-related virus transmitted to man by mosquitoes, was first described in the central part of sweden in the 1960s as clusters of patients with fever, arthralgia and rash. an average annual rate of 30 cases was recorded in the 1980s but no cases have been diagnosed during the last few years. nephropathia epidemica (ne) characterized by fever, abdominal pain and renal dysfunction has been known to cause considerable morbidity in sweden during the last 60 years but ... | 1996 | 8800805 |
| low ambient temperature decreases cadmium accumulation in the liver and kidneys of the bank vole (clethrionomys glareolus). | the importance of photoperiod and ambient temperature on the accumulation of cadmium in the liver and kidneys of bank voles was determined in the present study. males and females, aged 1 month, were given 3.0 micrograms cd ml-1 drinking water and divided into four groups according to photoperiod (16 h light/8 h dark and 8 h light/16 h dark) and ambient temperature (20 or 5 degrees c); liver and kidneys were removed for cadmium as well as copper, iron and zinc analyses at the end of 6 weeks. bank ... | 1996 | 8837457 |
| a combined stereotaxic adaptor and anaesthesia apparatus for microdialysis studies in small rodents. | intracerebral microdialysis in the bank vole (clethrionomys glareolus) challenges the accuracy and precision of the stereotaxic implantation technique because of the small brain size. in this paper, a miniaturized stereotaxic head holder is described that allows precise alignment of bone landmarks on the skull and prevents all movement after fixation by clamping the skull symmetrically at the os parietale and at the os nasale. in addition, the head holder is adapted for inhalation anaesthetic de ... | 1996 | 8884616 |
| removal of the olfactory system modifies male bank vole behaviour in the presence of females. | the role of the olfactory and vomeronasal systems of male bank voles in behavioural interaction with females was investigated. bulbectomy (obx), but not vomeronasalectomy (vnx), resulted in a decrease of female-stimulated ultrasonic calling by males, manifested as longer latency to the first call and fewer calls by obx males in comparison to vnx or sham-operated (sham) animals. obx males showed significantly fewer non-aggressive approaches but more attacks toward females. females were less aggre ... | 1996 | 24897157 |
| photoperiodic elevation of testicular zinc protects seminiferous tubules against fluoride toxicity in the bank vole (clethrionomys glareolus). | recent work has shown that a high fluoride (f) intake in rodents leads to histopathologic changes in the germinal epithelium of testes and to zinc deficiency in the testis and several other organs. the purpose of the present study was to determine whether an elecvation of testicular zinc concentration during fluoride exposure could protect the testes of bank vole from damage. the elevation of testicular zinc was achieved by exposing the bank voles to a long photoperiod (16 hr light/8 hr dark). t ... | 1996 | 8665403 |

| impact of an environmentally-realistic intake of cadmium on calcium, magnesium, and phosphate metabolism in bank voles, clethrionomys glareolus. | oral intake of cadmium can disrupt calcium metabolism in laboratory rodents. if this occurs in free-living wild rodents, reproductive potential, growth, and survival could be adversely affected. this study investigated whether an environmentally-realistic intake of cadmium (1.5-1.7 mg/kg bw/24h) by bank voles, clethrionomys glareolus, affected uptake and assimilation of calcium and also that of magnesium and phosphorus, two elements metabolized in close association with calcium. mineral metaboli ... | 1995 | 7661627 |
| reproductive costs and litter size in the bank vole. | the potential reproductive costs for free-ranging bank vole (clethrionomys glareolus) offspring and mothers were assessed by manipulating litter size and by determining the effects of nursing varied numbers of offspring. litter enlargement did not increase the number of weanlings per mother. the mass of juveniles was significantly lower in the enlarged litters and higher in the reduced litters, compared to the control group. however, the survival of juveniles from weaning aged three months did n ... | 1995 | 7644546 |
| home bedding modifies ultrasonic vocalization of infant bank voles. | bank vole,clethrionomys glareolus, pups, similar to many other infant rodents, emit ultrasonic vocalizations when they are removed from the nest and cooled. infants exposed to bedding from their home cage produced fewer and shorter calls than infants tested without bedding. sound frequencies were significantly higher in infants exposed to home bedding than in other experimental groups. these results provide evidence that infant bank voles are able to identify the presence of home bedding, probab ... | 1995 | 24234251 |
| blood supply to the abdominal and pelvic regions in the mediterranean pine vole, microtus duodecimcostatus (rodentia, arvicolidae). | the abdominal and pelvic blood supply of the mediterranean pine vole (microtus duodecimcostatus) is described. a total of 13 individuals (seven males, six females) captured in the field (sanaüja, spain) were analysed by injection of coloured latex solution and subsequent dissection. the arrangements observed in all specimens show some common traits in relation to the patterns established in other arvicolidae studied (arvicola terrestris, clethrionomys glareolus, microtus h agrestis). these share ... | 1995 | 8588705 |
| effects of predator removal on vertebrate prey populations: birds of prey and small mammals. | we studied the effects of removal of breeding nomadic avian predators (the kestrel, falco tinnunculus and tengmalm's owl, aegolius funereus) on small mammals (voles of the genera microtus and clethrionomys and the common shrew, sorex araneus) during 1989-1992 in western finland to find out if these predators have a regulating or limiting impact on their prey populations. we removed potential breeding sites of raptors from five manipulation areas (c. 3 km(2) each), whereas control areas had nest- ... | 1995 | 28306779 |
| nucleotide and deduced amino acid sequences of the m and s genome segments of a swedish puumala virus isolate. | the swedish puumala (puu) virus strain vindeln 83-l20, isolated from a bank vole trapped in 1983 near vindeln, västerbotten county, sweden, was characterized by nucleotide sequence analysis. the coding region of the m segment was determined by pcr followed by direct sequencing and the entire s segment was characterized by cloning and nucleotide sequence analysis. the genomic organization was found to be very similar to that of other puu virus strains regarding open reading frames, polypeptide si ... | 1995 | 8837894 |
| infestation of rodents with larval ixodes ricinus (acari: ixodidae) is an important factor in the transmission cycle of borrelia burgdorferi s.l. in german woodlands. | the ecology of borrelia burgdorferi johnson et al. s.l. was investigated from 1987 to 1993 in a preserved woodland in western germany near bonn. in selected biotopes, host-seeking ixodes ricinus l. were regularly collected by blanket dragging in 1987, 1988, and 1989 and screened for infection with b. burgdorferi. rodents were trapped monthly between april and october in 1988, 1990, 1991, and in the winter of 1992-1993, examined for antibodies to b. burgdorferi s.l., and inspected for feeding tic ... | 1995 | 8551503 |
| 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 |
| is the small mammal (clethrionomys glareolus) or the tick vector (ixodes ricinus) the primary overwintering reservoir for the lyme borreliosis spirochete in sweden? | we determined the capacity of bank voles (clethrionomys glareolus) to infect feeding ixodes ricinus ticks with borrelia burgdorferi sensu lato (infectivity), during june to october 1991 and june to september 1992 in south-central sweden. in both years, the infectivity of older voles to ticks was higher in august to september (48% to 59%) than in june to july (20% to 32%). we propose that the infectivity of bank vole populations in sweden decreases during winter and spring due to death of highly ... | 1995 | 8592387 |
| [leptospira infected rat population as probable cause of a fatal case of weil's disease]. | in the summer of 1992 a patient died of a leptospiral infection which he probably had contracted while he was swimming in an artificial lake in the region of tübingen/reutlingen. regarding the epidemiological role of leptospirosis the rodent population was investigated, because rats and mice were often seen in the surrounding area. 11 rats and 20 mice could be trapped. from their urine or kidneys two leptospiral serovars were isolated: serovar copenhageni from rattus norvegicus and serovar saxko ... | 1995 | 8593131 |
| fluoride accumulation and toxicity in laboratory populations of wild small mammals and white mice. | a laboratory experiment was conducted to compare the toxicological response and metabolism of inorganic fluoride by three species of wild mammals and laboratory white mice (mus musculus l.). the experimental populations of the wild species--the short-tailed field vole (microtus agrestis l.), the bank vole (clethrionomys glareolus l.) and the the wood mouse (apodemus sylvaticus l.)--were laboratory reared from wild stock, and all test animals were exposed to 0, 40 or 80 microgram f per ml in thei ... | 1995 | 8603928 |
| coding strategy of the s and m genomic segments of a hantavirus representing a new subtype of the puumala serotype. | the hantavirus strain vranica was previously reported to have been isolated from a bank vole in bosnia-hercegovina and associated with the occurrence of hemorrhagic fever with renal syndrome (hrfs) in humans. the complete cdna nucleotide sequences of the small (s) and medium (m) genomic rna segments of this virus were determined. major open reading frames were found in the s and m segment between nucleotide positions 43 and 1341 coding for a polypeptide of 433 amino acid residues and between nuc ... | 1995 | 7503698 |

| detection and subsequent sequencing of puumala virus from human specimens by pcr. | a sensitive method based on pcr was developed for the detection of puumala virus (puu) in human samples. the assay was found to be specific for puu-like strains and distinguished between these and hantaviruses of other serotypes. the detection limit was found to be 10(-5) focus-forming units. clinical samples were collected from patients with nephropathia epidemica in sweden and western russia. five whole blood samples collected from patients in russia with the acute phase of disease were found ... | 1995 | 7714178 |
| quantifying parameters in the transmission of babesia microti by the tick ixodes trianguliceps amongst voles (clethrionomys glareolus). | the estimation of two parameters in the transmission of babesia microti by the tick ixodes trianguliceps amongst small mammals, (1) the duration of infectivity in natural hosts and (2) the probability of transmission from an infected to a susceptible vole, is described. when b. microti was maintained by direct tick transmission, the probability of a complete cycle of transmission via the larval-nymphal and nymphal-adult transstadial routes was 1.0 and 0.71 respectively, but only if the larvae or ... | 1995 | 7724236 |
| [occurrence of coxiella burnetti antibodies in cattle, sheep and small terrestrial mammals in the western region of bohemia]. | the prevalence of antibodies to c. burnetii was studied in the karlovy vary district (the czech republic) between 1987 and 1989. sera of cows, sheep and heart eluates of small ground mammals were tested using the complement fixation test with c. burnetii antigen in phase ii (bodibion, mevak nitra, slovakia). titers greater or equal to 8 or 10 were considered as positive. cows from two large-scale farms were tested four times (the average number of every sampling was 339 cows). their seroprevalen ... | 1995 | 7762122 |
| sensitive detection of hantaviruses by biotin-streptavidin enhanced immunoassays based on bank vole monoclonal antibodies. | antigen capture enzyme-linked immunosorbent assays (elisas) based on detection of the viral nucleocapsid protein (n) were designed for rapid diagnosis of hantavirus infections. several combinations of bank vole (clethrionomys glareolus) monoclonal antibodies with various n-epitope specificities were used for the development of two double-antibody sandwich forms of elisa; puu virus ag-elisa for an exclusive detection of puumala-related viruses, and hantavirus ag-elisa for a more extensive detecti ... | 1995 | 7769041 |
| mapping of b-cell determinants in the nucleocapsid protein of puumala virus: definition of epitopes specific for acute immunoglobulin g recognition in humans. | the complete amino acid sequence of the puumala (puu) virus nucleocapsid protein (n), deduced from the genome of the prototype strain sotkamo, was synthesized as decapeptides with 5-amino-acid overlaps. by use of the pepscan method, 86 peptides were examined for reactivity with sera from serologically confirmed nephropathia epidemica (ne) patients and 11 puu virus n-specific bank vole monoclonal antibodies. the human sera showed reactivity with several different regions, while only one of the mo ... | 1995 | 7536616 |
| prevalence of antibodies to borrelia burgdorferi in danish rodents. | six rodent species from six danish localities were examined for antibodies to borrelia burgdorferi by immunofluorescence assay (ifa). a total of 1097 specimens were tested using a serum titre of 1:8. the wild mice apodemus sylvaticus and a. flavicollis had high prevalences of b. burgdorferi antibodies of 42.1% and 27.9% respectively, but the vole microtus agrestis also showed an exceptionally high prevalence of 32.7%. clethrionomys glareolus had a low average prevalence of 17.4%. the lowest and ... | 1995 | 7612254 |
| clethrionomys glareolus, but not apodemus flavicollis, acquires resistance to ixodes ricinus l., the main european vector of borrelia burgdorferi. | the european rodents clethrionomys glareolus (bank vole) and apodemus flavicollis (yellow-necked-mouse) are important hosts of the tick species ixodes ricinus, the main european vector of borrelia burgdorferi. we have addressed the question whether or not these tick hosts develop resistance to i. ricinus larvae. c. glareolus and a. flavicollis were exposed to 40 i. ricinus larvae for five consecutive times at two week intervals. resistance was tested by the following parameters: percentage of ti ... | 1995 | 7624158 |
| serological evidence for the reservoir hosts of cowpox virus in british wildlife. | the reservoir host of cowpox virus in western europe is not known, but epidemiological evidence from human and feline infections indicates that the virus is probably endemic in small wild rodents. therefore, serum and tissue samples were collected from a variety of wild british mammals and some birds, and tested for evidence of orthopoxvirus infection. antibody reacting with cowpox virus was detected in 9/44 (20%) bank voles (clethrionomys glareolus), 8/24 (33%) field voles (microtus agrestis), ... | 1995 | 7641833 |
| mortality factors in a cyclic vole population. | the causes of cyclic fluctuations in microtine rodent populations are still a bone of contention. in particular, the actual causes of mortality in the different phases of the 3-4-year vole are an enigma. we present results from studies of radio-collared voles (microtus agrestis, m. rossiaemeridionalis and clethrionomys glareolus), which show that small mustelid predation was the major mortality factor of voles in the decline phase, but had less importance in the increase phase of the 3-year popu ... | 1995 | 7644548 |
| strain variation of lyme disease spirochetes isolated from ixodes ricinus ticks and rodents collected in two endemic areas in switzerland. | the relationship among lyme borreliosis, borrelia genospecies, rodent reservoirs, and ixodes ricinus l. ticks was studied in two endemic areas in switzerland. ear punch biopsies and sampling of internal organs were used to isolate borrelia burgdorferi (johnson, schmid, hyde, steigerwalt and brenner) from small mammals, apodemus sylvaticus l., a. flavicollis melchoir, clethrionomys glareolus schreber. spirochetes were isolated from ear tissue and spleen of the rodents. isolates were homogeneous a ... | 1995 | 7650703 |

| reverted virulence of attenuated tick-borne encephalitis virus mutant is not accompanied with the changes in deduced viral envelope protein amino acid sequence. | serial passages of tick-borne encephalitis (tbe) virus strain 4387 isolated from the liver and lungs of the bank vole through the salivary glands of ixodes ricinus ticks led to a reduction of its virulence for laboratory mice infected via peripheral route. when attenuated mutants were passaged through mouse brains, virulent phenotypes have appeared in the 3rd mouse passage. after 5 consecutive passages the virus was more pathogenic for mice after peripheral inoculation than the parental 4387 str ... | 1994 | 7817894 |
| scaning electron microscopy of capillaria muris sylvatici from clethrionomys glareolus with reference to the zoonotic species. | species of the genus capillaria are numerous. many of them are parasites of different species of vertebrates, including man, causing various pathological manifestations. the taxonomy of the capillariids is a complicated one. in the present study, light and scanning electron microscopes were used to illustrate and clarify the taxonomic features of capillaria muris sylvatici. this capillus or hair nematode was recovered from the vole clethrionomys glareolus. the results were discussed with referen ... | 1994 | 7844433 |
| 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 |
| borrelia burgdorferi in rodents (apodemus flavicollis and a. sylvaticus): duration and enhancement of infectivity for ixodes ricinus ticks. | ixodes ricinus is an important vector of borrelia burgdorferi in europe, and small rodents (apodemus flavicollis, a. sylvaticus and clethrionomys glareolus) are important sources for infecting ticks. in this study, we examined their reservoir role by studying the duration of their infectivity for ticks. a. flavicollis and a. sylvaticus mice captured in nature were exposed to uninfected i. ricinus larvae at different times after their capture: 10 days, and 2, 7, 11, 14 and 40 months. ticks were e ... | 1994 | 7957795 |
| 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 |
| isolation of a puumala-like virus from mus musculus captured in yugoslavia and its association with severe hemorrhagic fever with renal syndrome. | an outbreak of severe hemorrhagic fever with renal syndrome (hfrs) occurred in 1988 in pozarevac, serbia, yugoslavia. the disease was diagnosed in 4 children and 1 adult, and 1 of the children died. rodents were captured from the same area and virus isolation attempted. a hantavirus, poz-m1, was isolated from lung tissues of hantavirus antigen-positive mus musculus. serology and restriction enzyme digestion of polymerase chain reaction-amplified segments from this virus showed that it was a stra ... | 1994 | 7506281 |
| influence of herbivory on caesium turnover in a forest ecosystem. | the effect of herbivory by bank vole (clethrionomys glareolus) and moose (alces alces) in relation to litterfall in a boreal forest is analysed. the main purpose is to estimate the relative importance of these processes for the transfer of caesium-137 to soil. biomasses of litterfall and food consumption were selected from different forest biotopes. the analysis of the input and output of caesium-137 in the vole and moose populations is based on mass balance calculations for caesium-137 in stead ... | 1994 | 7839117 |
| behaviour of cyclic bank voles under risk of mustelid predation: do females avoid copulations? | mustelid odours have been shown to suppress breeding in captive bank voles (clethrionomys glareolus) from cyclic populations (ylönen 1989; ylönen and ronkainen 1994). the mechanism behind the suppression is unknown. based on a series of behavioural trials and breeding experiments with pairs of bank voles in breeding condition, we suggest that the primary cause for breeding suppression is a change in female mating behaviour. experimental female-male pairs (n=34) exposed to mustelid odour decrease ... | 1994 | 28313633 |
| the curious normality of the synaptic association between the sex chromosomes of two arvicoline rodents: microtus oeconomus and clethrionomys glareolus. | in all eight species of arvicoline (microtine) rodents previously described, the x and y chromosomes have remained asynaptic throughout pachynema. since synapsis is presumed to be a prerequisite for crossing over, it has been concluded that the sex chromosomes in these species are also achiasmatic, but the mechanism(s) of their disjunction remains an enigma. their asynaptic, achiasmatic condition has been attributed to loss of the pseudoautosomal region (borodin et al. 1991; carnero et al. 1991; ... | 1994 | 8083057 |
| densities of microtime rodents along a pollution gradient from a copper-nickel smelter. | population densities of microtine rodents were studied along an air pollution gradient in the kola peninsula, russia, by long-term and short-term trapping. the study area is affected by high sulphur dioxide and heavy metal emissions from the severonikel copper-nickel smelter in monchegorsk. the density of clethrionomys rufocanus, the most abundant vole species in the area, was lowest close to the smelter and increased with distance up to the farthest, less polluted trapping sites. clethrionomys ... | 1994 | 28313738 |
