A total of 136 soil samples collected from nonsericultural areas of 18 prefectures of Japan were examined for the distribution of Bacillus thuringiensis. Of 6910 isolates referable to the Bacillus cereus-B. thuringiensis group, 189 (2.7%) produced parasporal inclusions (PIs). Among these PI-forming isolates, only 66 (34.9%) were identified as B. thuringiensis H serotypes 3a, 4a:4c, 5a:5c, 8a:8c, 10, 11a:11c and 17. Of the remaining 123 isolates, 84 were well-motile but untypeable by H antisera against the known B. thuringiensis serotypes 1-21, and 39 were untestable because of nonmotility or marked autoagglutination. The results suggested that B. thuringiensis flora in soils was remarkably different from that in the sericultural environment.
