RESUMO
Relationships of the somatic antigens among Clostridium botulinum strains have been investigated by tube agglutination and agglutinin absorption tests. Results revealed a relationship by which strains of C. botulinum are grouped by their proteolytic capacity rather than by the type of specific toxin produced. Thus, C. botulinum type E and its nontoxigenic variants, which are nonproteolytic, share common somatic antigens with the nonproteolytic strains of types B and F. Absorption of antiserum of a strain of any one type with antigen of any of the others removes the antibody to all three types. In the same manner, C. botulinum type A shares somatic antigens with the proteolytic strains of types B and F, and absorption of any one antiserum with an antigen of either of the other two types removes the antibody to all three types. Partial cross-agglutination of C. sporogenes, C. tetani, and C. histolyticum with the somatic antisera of the proteolytic group was also observed.
