| u.s.-type babesia microti isolated from small wild mammals in eastern hokkaido, japan. | our previous report demonstrated that small wild rodents in japan harbored two types of novel babesia microti-like parasites (kobe and hobetsu types), but not the type widely distributed throughout the temperate zones of north american and eurasian continents (u.s. type). in this study, we surveyed small wild mammals collected at various places in the northern part of japan, seeking for u.s.-type b. microti. a total of 197 small mammals comprising 10 species, apodemus speciosus, a. argenteus, cl ... | 2004 | 15353841 |
| karyotypic evolution and organization of the highly repetitive dna sequences in the japanese shrew-moles, dymecodon pilirostris and urotrichus talpoides. | the karyological relationship and organization of highly repetitive dna sequences in japanese shrew-moles were studied by zoo-blot hybridization and fluorescence in situ hybridization (fish). when the genomic dna of the eastern race of urotrichus talpoides was digested with psti, three fragments of highly repetitive dna sequences, approximately 0.7, 0.9, and 1.4 kb in length, were observed as distinct bands. the results of fish in the eastern race of u. talpoides using these three fragments sepa ... | 2005 | 16103657 |
| the delayed quinacrine mustard fluorescence from the c-blocks of apodemus argenteus is due to the introduction of nicks into the dna. | "delayed qm-fluorescence" refers to the unusual kinetics of fluorescence from most of the c-heterochromatic regions of the chromosomes of the small japanese field mouse apodemus argenteus. when stained with quinacrine mustard (qm-stained), these c-heterochromatic regions emit weak fluorescence immediately after exposure to blue light (bl); they emit bright fluorescence within a few minutes; and the intensity of the fluorescence gradually decreases after maximum fluorescence has been recorded. to ... | 2007 | 17867860 |
| molecular phylogeny of a newfound hantavirus in the japanese shrew mole (urotrichus talpoides). | recent molecular evidence of genetically distinct hantaviruses in shrews, captured in widely separated geographical regions, corroborates decades-old reports of hantavirus antigens in shrew tissues. apart from challenging the conventional view that rodents are the principal reservoir hosts, the recently identified soricid-borne hantaviruses raise the possibility that other soricomorphs, notably talpids, similarly harbor hantaviruses. in analyzing rna extracts from lung tissues of the japanese sh ... | 2008 | 18854415 |
| 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 |
| host switch during evolution of a genetically distinct hantavirus in the american shrew mole (neurotrichus gibbsii). | a genetically distinct hantavirus, designated oxbow virus (oxbv), was detected in tissues of an american shrew mole (neurotrichus gibbsii), captured in gresham, oregon, in september 2003. pairwise analysis of full-length s- and m- and partial l-segment nucleotide and amino acid sequences of oxbv indicated low sequence similarity with rodent-borne hantaviruses. phylogenetic analyses using maximum-likelihood and bayesian methods, and host-parasite evolutionary comparisons, showed that oxbv and asa ... | 2009 | 19394994 |
| evolutionary insights from a genetically divergent hantavirus harbored by the european common mole (talpa europaea). | the discovery of genetically distinct hantaviruses in shrews (order soricomorpha, family soricidae) from widely separated geographic regions challenges the hypothesis that rodents (order rodentia, family muridae and cricetidae) are the primordial reservoir hosts of hantaviruses and also predicts that other soricomorphs harbor hantaviruses. recently, novel hantavirus genomes have been detected in moles of the family talpidae, including the japanese shrew mole (urotrichus talpoides) and american s ... | 2009 | 19582155 |
