Subspecies-specific haemagglutination patterns of fimbriated Bacillus thuringiensis spores.
Electron microscopy revealed fimbrial appendages (pili) of three types on the surface of Bacillus thuringiensis spores. Fimbriated spores induced mannose-resistant agglutination of rat, guinea pig and/or chicken red blood cells. Each haemagglutination pattern correlated with the subspecies of a given B. thuringiensis strain, rather than with its flagellar serotype. Fimbriation and haemagglutination patterns of B. thuringiensis spores are considered to be of possible taxonomic value.
