| rickettsial diseases and ectoparasites from military bases in japan. | ectoparasitic arthropods are often vectors of rickettsiosis. we conducted a survey of ectoparasites on u.s. military facilities throughout japan with the use of specimens submitted by pest control, public health, and veterinary personnel. over 1,600 individual ectoparasites were collected. fifteen species were identified, including several significant vectors of human diseases such as scrub typhus and rickettsial spotted fevers. these ectoparasites included ctenocephalides felis , haemaphysalis ... | 2015 | 25548900 |
| isolation of orientia tsutsugamushi from leptotrombidium fuji and its characterization. | in our attempts to isolate orientia tsutsugamushi from trombiculid mites, a strain was successfully isolated from leptotrombidium fuji collected in aichi prefecture, japan. this is the first case of isolation of o. tsutsugamushi from l. fuji. a phylogenetic analysis based on the base-sequence homology of the 56-kda type-specific antigen-gene indicated that the strain is a new type which is not closely related to any strains analyzed previously. three strains isolated from leptotrombidium pallidu ... | 2000 | 10789509 |
| transmission of rickettsia tsutsugamushi from apodemus speciosus, a wild rodent, to larval trombiculid mites during the feeding process. | transmission of rickettsia tsutsugamushi (rt) from a rodent to trombiculid mites was studied. wild rodents, apodemus speciosus, were subcutaneously inoculated with karp strain of rt, and larval trombiculid mites were released on the ear lobes for feeding, 10 and 20 days after infection. isolation of rt was performed from individual mites or pools of 2 to 7 mites by the mouse passage method. from apodemus 10 days after rt infection, possibly at the time of high rickettsiaemia, the infection rates ... | 1990 | 2127292 |
