More than 500 patients of tsutsugamushi disease have been reported in Kagoshima Prefecture since 1955. We have, therefore, made a series of investigations in an attempt to determine the vector trombiculid species in this prefecture. Trombiculid larvae were collected from wild rodents, from the soil of endemic areas, and from the black bakelite plates set on the ground. Also attempted were the isolation of Rickettsia tsutsugamushi (R. t.) from the collected mites and the detection of anti-R. t. antibodies from the sera of the sentinel mice exposed to trombiculid larvae in the endemic foci. As the results, 351 fed larvae of trombiculid mites consisting of 2 genera and 9 species were collected from the wild rodents, and 544 unfed larvae belonging to 2 genera and 7 species were recovered by the bakelite plate method; Leptotrombidium scutellare and L. pallidum were included in both of these groups of mites collected. However, the isolation of R. t. from the unfed L. scutellare was unsuccessful. Three out of 174 sera of the experimental mice exposed to trombiculid larvae in the endemic foci were positive for R. t. antigens by the indirect immunofluorescence method.
