Extremely high frequency of common flagellar antigens between Bacillus thuringiensis and Bacillus cereus.
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.
