| genotoxic assessment of small mammals at an illegal dumpsite at the aomori-iwate prefectural boundary. | in 2003, we examined the chromosomes of grass voles at an illegal dumpsite at the aomori-lwate prefectural boundary. in subsequent years, from 2003-2006, we surveyed the chromosomes of four species of small mammals, namely, the japanese grass vole (microtus montebelli), the large japanese field mouse (apodemus speciosus), the small japanese field mouse (a. argenteus), and the greater japanese shrew mole (urotrichus talpoides). each annual survey revealed, both on a yearly basis and during the en ... | 2009 | 19341331 |
| survey of babesia microti infection in field rodents in japan: records of the kobe-type in new foci and findings of a new type related to the otsu-type. | of 247 rodents comprising 5 genera and 7 species collected at 17 sites throughout japan from 2003 to 2005, babesia microti was detected microscopically and by polymerase chain reaction (pcr) in 36 rodents comprising 2 genera and 3 species from 12 sites. based on the analysis of small subunit ribosomal rna gene (ssurdna) sequences, the kobe-type, the etiological type of the first japanese case of human infection was found in apodemus speciosus and apodemus argenteus in aomori, the northernmost pr ... | 2007 | 17237595 |
| isolation of pathogenic yersinia enterocolitica 1b/o:8 from apodemus mice in japan. | yersinia enterocolitica was isolated from 15.7% (88/560) of wild rodents captured in 15 prefectures in japan. prevalences by rodent species were 18.0% (70/388) in japanese field mice (apodemus speciosus), 20% (14/71) in small japanese field mice (apodemus argenteus), and 11% (4/38) in gray red-backed vole (myodes rufocanus bedfordiae), suggesting that these rodent species are important reservoirs of y. enterocolitica. although most of the isolates were identified as biotype 1a, the pathogenic bi ... | 2015 | 25380368 |
