| eimerians from different karyotypes of the japanese wood mouse (apodemus spp.), with descriptions of two new species and a redescription of eimeria montgomeryae lewis and ball, 1983. | examination of 131 wood mice (apodemus spp.) representing 2 species and 6 subspecies collected from the japanese islands of hokkaido, honshu, kyushu, and tsushima showed that 70 mice (53%) had coccidian oocysts in their feces. these included 21 of 42 (50%) apodemus argenteus argenteus; 7 of 14 (50%) apodemus argenteus hokkaidi; 2 of 3 (67%) apodemus argenteus sagax; 3 of 9 (33%) apodemus speciosus ainu; 36 of 61 (59%) apodemus speciosus speciosus; and 1 of 2 (50%) apodemus speciosus tusimaensis. ... | 1985 | 4093813 |
| comparison of ehrlichia muris strains isolated from wild mice and ticks and serologic survey of humans and animals with e. muris as antigen. | in metropolitan tokyo, the ehrlichia muris seropositivity rate of 24 wild mice was 63% in hinohara village, but in the surrounding areas, it was 0 to 5%. this finding suggests that the reservoir of e. muris is focal. among the 15 seropositive mice, ehrlichiae were isolated from 9 apodemus speciosus mice and 1 a. argenteus mouse, respectively. five ehrlichial isolates were obtained from 10 ticks (haemaphysalis flava) collected in asuke town, aichi prefecture, where the e. muris type strain had be ... | 1999 | 10074536 |
| a trend of central versus peripheral structuring in mitochondrial and nuclear gene sequences of the japanese wood mouse, apodemus speciosus. | a phylogeographic analysis was performed on japanese endemic wood mice (apodemus speciosus) using nuclear interphotoreceptor retinol binding protein (irbp) gene sequences (1,152 bp), together with previously published mitochondrial cytochrome b (cyt b) data. in the irbp analysis, 40 haplotypes were recovered from 84 individuals by statistical and subcloning methods. substantial sequence variation was determined from the irbp data (pi=0.0047), and no significant evidence of recombination was dete ... | 2008 | 18393564 |
| genetic and antigenic characterization of newly isolated bovine toroviruses from japanese cattle. | torovirus, a member of the coronaviridae family, is a gastrointestinal infectious agent that has been identified in humans, cattle, pigs, and equines. toroviruses, except equine torovirus, are difficult to propagate in cell culture; indeed, to date, only the aichi/2004 strain of bovine torovirus (btov) has been isolated among the human, bovine, and porcine toroviruses. in the present study, four cytopathogenic btovs were isolated from diarrheal feces of the cattle using the hrt-18 cell line, and ... | 2010 | 20220164 |
| genetic characterization and susceptibility on poultry and mammal of h7n6 subtype avian influenza virus isolated in japan in 2009. | from february to march 2009, six strains of h7n6 subtype avian influenza virus were isolated from quails in three farms in aichi prefecture in japan. the isolates were shown to be low pathogenic for chicken by the examination performed using the "manual of standards for diagnostic tests and vaccines" by world organisation for animal health (oie). the deduced amino acid sequence at the cleavage site was pe (i/q/l) pkrr (nucleotide sequences were cct gaa (a/c) (t/a) a cc (a/g) aaa aga aga), sugges ... | 2010 | 21111917 |
