| fatal experimental babesia microti infections in the norwegian lemming, lemmus lemmus (l.). | experimental infections of babesia microti in laboratory-reared clethrionomys glareolus revealed that approximately 15% of the erythrocytes were infected with single ring forms during peak parasitemia. infected erythrocytes could be detected in blood smears up to one month post infection. c. glareolus treated with a single injection of depo-medrol i.m. two days prior to infection displayed a four-fold increase in number of infected erythrocytes at peak parasitemia, 35% of which contained more th ... | 1978 | 357267 |
| hemorrhagic fever with renal syndrome (nephropathia epidemica) in norway: seroepidemiology 1981-1985. | an indirect fluorescent antibody technique (ifat) was applied to serologically confirm the clinical diagnosis in 507 nephropathia epidemica (ne) suspected patients. hantaan virus (hv), the agent of korean hemorrhagic fever, which is serologically related to the ne agent, was used as antigen. both igg and igm reactions were detected. high levels of igg antibodies to hv were common, even in the acute phase of illness. over a 5-year period, a total of 35% of the ne suspected patients revealed antib ... | 1988 | 2900551 |
| nephropathia epidemica in norway: antigen and antibodies in rodent reservoirs and antibodies in selected human populations. | nephropathia epidemica (ne) antigen was detected by ifat (indirect fluorescent antibody technique) in the lungs of 14 of 97 bank voles (clethrionomys glareolus) collected in three endemic areas. the distribution of antigen positive voles within an endemic location was scattered. antibodies to korean hemorrhagic fever (khf) virus antigens were detected by ifat in 12 of 14 ne antigen positive bank voles and in 15 of 83 that were antigen negative. ne antigen positive voles exhibited higher antibody ... | 1984 | 6146649 |
| 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 |
| the propensity of voles and mice to transmit borrelia burgdorferi sensu lato infection to feeding ticks. | lyme borreliosis (lb) caused by the spirochete borrelia burgdorferi sensu lato is the most common tick-borne zoonosis in the northern hemisphere. b. burgdorferi s.l. can infect humans and wild and domestic animals. ixodes ricinus is the main vector, and small rodents are the most important mammalian reservoirs hosts of b. burgdorferi s.l. in europe. the prevalence of b. burgdorferi s.l. in i. ricinus ticks from captured rodents, calculated specific infectivities, and transmission coefficients we ... | 2013 | 23849517 |
| 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 |
| bank voles in linear habitats show restricted gene flow as revealed by mitochondrial dna (mtdna). | genetic structure of bank vole populations in linear river bank habitat in southeast norway was determined from analyses of dna sequences for the mitochondrial d-loop. animals were sampled at sites separated by 1 km, along two forested river banks separated by approximately 100 m of open water. twenty-six distinct haplotypes were found among 120 voles. the voles showed significant deviation from panmixis on both sides of the river. animals from the same site or from sites 1 km apart were more li ... | 1998 | 9787447 |
| lack of concordance between mtdna gene flow and population density fluctuations in the bank vole. | the genetic structure of bank voles clethrionomys glareolus was determined from analyses of mitochondrial dna (mtdna) sequences, and compared with previous data on geographical synchrony in population density fluctuations. from 31 sample sites evenly spaced out along a 256-km transect in se norway a total of 39 distinct mtdna haplotypes were found. the geographical distribution of the haplotypes was significantly non-random, and a cladistic analysis of the evolutionary relationship among haploty ... | 1997 | 9262013 |
