| 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 |
| detection of babesia microti-like parasite in filter paper-absorbed blood of wild rodents. | the first case of human babesiosis was reported in japan. the epidemiology of this disease in japanese nature remains unclear. in this study, 97 common field mice captured in hokkaido, japan, were examined. blood specimens absorbed onto filter papers were eluted and tested by nested pcr using specific primers for the b. microti nuclear small subunit rrna genome. twenty-three percent (11/47) of apodemus speciosus and four percent (2/50) of clethrionomys rufocanus were positive. the 159-bp primary ... | 2002 | 11913551 |
| 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 |
| studies on babesia first found in murine in japan: epidemiology, morphology and experimental infection. | during the period from november 1980 to september 1982, 314 small wild mammals were captured in 5 localities in japan. twenty-six out of 86 apodemus speciosus and one out of 6 a. argenteus both species captured in shiga prefecture (35 degrees 02'n, 135 degrees 50'e, 330 m elev .) were positive for babesia. the parasitemia in those animals was generally low. the infection rate did not show any significant difference between sexes of the host or between seasons, whereas it tended to go up with the ... | 1984 | 6730782 |
