    Abstract

    Ribosomal RNA gene restriction patterns have been determined for 43 strains of Bacillus thuringiensis representing 10 serovars and eight reference strains of B. anthracis, B. cereus and B. mycoides. Strains within a B. thuringiensis serovar produced highly related or identical ribotype patterns: in particular, 12 strains of serovar israelensis, five strains of serovar kurstaki, two strains of serovar galleriae and three strains of serovar aizawa produced ribotype patterns consistent with serotype designations. Moreover, variety tenebrionis (serotype 8a8b), a coleopteran pathogen, could be distinguished from the more common lepidopteran pathogens of this serotype (serovar morrisoni) by ribotyping. The correlation of ribotype patterns with serotype suggests a clonal population structure for B. thuringiensis.
