| 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 |
| 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 |
| dynamics, co-infections and characteristics of zoonotic tick-borne pathogens in hokkaido small mammals, japan. | many of the emerging infectious diseases originate in wildlife and many of them are caused by vector-borne pathogens. in japan, zoonotic tick-borne pathogens (tbps) are frequently detected in both ticks and wildlife. here, we studied the infection rates of potentially zoonotic species, including anaplasma, ehrlichia, neoehrlichia and babesia spp., in hokkaido's most abundant small mammals as they relate to variable extrinsic factors that might affect the infection rates of these pathogens. a tot ... | 2016 | 27166277 |
| motor innervation of the mole and shrew snout muscles by means of horseradish peroxidase technique. | the axonal transport method of the horseradish peroxidase (hrp) was used for defining the anatomical background of the snout movements in 54 japanese shrew-moles, urotrichus talpoides, 4 temminck's moles, mogera wogura, and 21 big-clawed shrews, sorex unguiculatus. either snout muscle or proximal stump of the facial nerve on one side was exposed to hrp. the results obtained from this experimental study were as follows: hrp-containing cells were found either ipsilaterally or bilaterally in the fa ... | 1984 | 6234823 |
| cardiac-like musculature of the intrapulmonary venous wall of the long-clawed shrew (sorex unguiculatus), common tree shrew (tupaia glis) and common marmoset (callithrix jacchus). | the cardiac-like musculature is distributed not only in the heart wall but also in the intrapulmonary venous wall in a few species of insectivores. it has been suggested that the evolutionary origin of venous cardiac-like musculature may be traceable to a basic stock of certain mammalian lines of descent. so, it is important to clarify whether the musculature may be a common structure in lower mammals from insectivores to primates and to examine the functional significance of the structure. | 1997 | 8986302 |
