| the domestication of crocidura dsinezumi as a new laboratory animal. | the dsinezumi shrew (crocidura dsinezumi), a small insectivore, has been bred for the first time as a laboratory animal. the original animals were captured using sherman's live traps and transferred into wooden cages. after several generations they were housed in plastic cages. their diet consisted of trout pellets, cat food, and water provided ad libitum. monogamous pairs were housed together for 2-3 weeks for mating, and the male was separated from the female during delivery and nursing. in ca ... | 1992 | 1451754 |
| location and ultrastructure of borrelia japonica in naturally infected ixodes ovatus and small mammals. | the internal organs of ixodes ovatus and the ears of wild rodents (apodemus speciosus, eothenomys smithii) and an insectivore (crocidura dsinezumi) were cultured to isolate borreliae; positive samples were examined for the distribution and dissemination of spirochetes in the host tissues using electron microscopy. seven isolates were derived from the unfed ticks and the three species of mammals. these isolates were identified as borrelia japonica judging from the outer surface protein profile us ... | 1997 | 9087963 |
| human babesiosis in japan: epizootiologic survey of rodent reservoir and isolation of new type of babesia microti-like parasite. | we have carried out epizootiologic surveys at various sites in japan to investigate wild animals that serve as reservoirs for the agents of human babesiosis in the country. small mammals comprising six species, apodemus speciosus, apodemus argenteus, clethrionomys rufocanus, eothenomys smithii, crocidura dsinezumi, and sorex unguiculatus, were trapped at various places, including hokkaido, chiba, shiga, hyogo, shimane, and tokushima prefectures. animals harboring babesia microti-like parasites w ... | 2001 | 11724838 |
| morphometric geographic variation in the asian lesser white-toothed shrew crocidura shantungensis (mammalia, insectivora) in east asia. | this study investigated geographic variation in the asian lesser white-toothed shrew, crocidura shantungensis miller, 1901, among a number of localities in east asia, including the korean peninsula, tsushima island, cheju island, and taiwan, using univariate and multivariate analyses of cranial morphometric characters. sexual differences were found in taiwanese shrews, but were not evident in those from korea or tsushima. the samples from taiwan had a larger overall cranial size than those from ... | 2003 | 12832832 |
| scanning electron microscopic study on the lingual papillae of the japanese insectivora. | the tongue and lingual papillae of the japanese insectivora, the shinto shrew (sorex caecuiens saevus), the long-clawed shrew (s. unguiculatus), the dsinezumi shrew (crocidura dsinezumi dsinezumi) and the japanese water shrew (chimarrogale himalyica platycephala), were observed by scanning electron microscope. the tongue of these animals had two vallate papillae. in two species of the sorex a papilla in the vallate papilla was surrounded by two separated trenches, but in the other species it was ... | 1989 | 2748079 |
| the variable heartbeat of japanese moles (mogera spp.). | this report demonstrates the variable cardiac rhythm in two species of subterranean mole, the large japanese mole (mogera wogura) and the lesser japanese mole (mogera imaizumii). the phenomenon was revealed using x-ray videos of m. wogura and investigated in detail using electrocardiogram (ecg) traces recorded with implanted electrodes in this species and m. imaizumii. cessation of heartbeat and extended r-r intervals were observed in the ecgs from both species during short bouts of rest in wake ... | 2019 | 31612249 |
