Bacillus cereus isolates, recovered from natural environments of Japan, were examined for their flagellar (H) antigenicities with the reference H antisera against Bacillus thuringiensis serotypes H1-H55. Of 236 B. cereus isolates tested, 165 (70%) were agglutinated with the reference antisera available. The frequencies of seropositive isolates were: 77% in soils, 68% on phylloplanes, and 60% in animal fecal populations. Among the 45 H serogroups detected, the serovar shandongiensis (H22) was the predominant, followed by the serovars entomocidus (H6), indiana (H16), pakistani (H13), and neoleonensis (H24ab). These five H serovars were commonly distributed in the three populations from different sources. © 2002 Federation of European Microbiological Societies. Published by Elsevier Science B.V.
