RESUMO
Clostridium botulinum type E antigens prepared from washed cells by either Formalin treatment or heating at 100 C were used for immunizing rabbits. Agglutination tests showed that high levels of antibody were produced by both types of preparations. Flagellar antigens were highly strain-specific, whereas the somatic antigens were sufficiently similar to produce complete cross-agglutination. One toxigenic strain produced toxigenic and nontoxigenic progeny which were physiologically and antigenically identical in all other respects. Other nontoxigenic strains whose growth, physiological, and morphological characters were identical to type E and strains which had some physiological differences completely cross-agglutinated with type E strains via the somatic antigen. Neither type of antiserum agglutinated other clostridia against which they were tested except for C. acetobutylicum. This reaction seems to be due to a nonspecific anamnestic response and does not appear to be related to the immunizing strains. The nontoxigenic strains studied seem to have no greater antigenic differences from type E strains than the type E strains have from each other.
