Abstract
The clinical findings of tsutsugamushi disease and the fauna of trombiculid mites in HiroshimaPrefecture were studied in this report. We reviewed 63 cases of tsutsugamushi disease occurring between1990 and 1999, and most of cases were contracted in the area around the midportion of the Oota River (55 cases; 87.3%). Of these, 30 cases (47.1%) lived in Asakita-ku in Hiroshima City. Escharwas detected in 33/19 (84.6%) cases, and 97.6% (40/41), 88.9% (16/18) patients showed eruptionand lymphadenopathy respectively. Biochemical examination revealed liver dysfunction in 38.1% (8/21) patients. Of the 11 cases examined on peripheral blood smear, atypical lymphocytes weredetected in 10 cases (90.9%). Fifty-five cases (90.2%) occurred during the restricted season betweenSeptember and December each year. The predominance of Leptotrombidium scutellare was verified bycollection of trombiculid mites along the basin of the Oota River. Serum antibody titration on a patientin Asakita-ku showed reaction to Kawasaki type antigen definitive to L. scutellare. Therefore, wespeculate that L. scutellare is a candidate for the vector of Orientia tsutsugamushi in Hiroshima Prefecture.
