Of the 314 inhabitants 120 were from Nagasaki city, 50 from Shimabara city, 50 from Fukue city, 50 from Oseto town and 44 from Wakamatsu town. Mean positive rate in Nagasaki prefecture was 5.1 per cent. The highest positive rate was 8.0 per cent from Oseto own and the lowest one was 2.0 per cent from Shimabara city. However these results were not significantly different according to the x^2-test. The level of antibody in positive cases ranged from 1:20 to 1:80 in serum dilution and the positive rate at each decade ranged from 4.0 per cent at the 4th decade to 15.0 per cent at the 3rd decade. These results were, however, not significant when checked by x^2-test. These results indicate that wild rodents had been already infected by Rickettsia tsutsugamushi in some areas before we found clinical cases of Rickettsia tsutsugamushi in Nagasaki prefecture., 熱帯医学 Tropical medicine 26(4). p157-164, 1984}, pages = {157--164}, title = {長崎県におけるつつが虫病の血清疫学的研究}, volume = {26}, year = {1984} }
