Pure spore antigens for the immunization of rabbits were prepared by enzymic digestion of vegetative components and separation of the cleaned spores in polyethylene glycol. Spore antisera were prepared to strains representative of toxigenic Clostridium botulinum type E; nontoxigenic boticin E-producing variants; nontoxigenic nonproducers of boticin E; nontoxigenic "atypical" strains, which differ somewhat from C. botulinum type E in their physiology; C. botulinum types A and B; and C. bifermentans. They were tested against these and additional strains representative of the above groups, other types of C. botulinum, and other Clostridium species. There was no evidence of agglutination of flagellar or somatic antigens of vegetative cells by these antisera. Agglutination and agglutinin absorption tests showed common antigens among toxigenic type E strains and nontoxigenic variants, both producers and nonproducers of boticin E. Some nontoxigenic "atypical" strains varied in their ability to be agglutinated by type E antisera, and others did not agglutinate at all. Of those atypical strains that were not agglutinated, one was agglutinated by C. bifermentans antiserum. Antisera prepared against C. botulinum types A and B and C. bifermentans did not agglutinate the spores of type E or its variants nor share antigens common to each other. Similarly, antisera to type E, its nontoxigenic variants, and nontoxigenic atypical strains did not agglutinate other C. botulinum types or any other Clostridium species investigated.
