title: Serotyping of Bacillus thuringiensis environmental isolates by extracellular heat-stable somatic antigens.
abstract: A total of 525 Bacillus thuringiensis environmental isolates, belonging to the five flagellar (H) serovars (alesti, sotto, kenyae, aizawai, and morrisoni), were serotyped by extracellular heat-stable somatic antigens (HSSAs). The isolates belonging to a given H serovar were assigned to a single HSSA serogroup at a high frequency, 87-100%. This indicates that the extent of HSSA variation within a single H serovar is small in the field populations of these B. thuringiensis serovars.
