ABSTRACT

ELLNER, PAUL D. (University of Vermont, Burlington), AND STANLEY S. GREEN. Serology of the soluble antigens of the pathogenic clostridia. J. Bacteriol. 86:1084–1097. 1963.—Soluble antigens of 42 strains, representing nine species of clostridia commonly occurring in human infections, were prepared by growing the organisms in a nonantigenic medium. Serological studies demonstrated the occurrence of considerable strain variation within each species. Interactions among the nine species, as well as with the previously characterized Clostridium perfringens, were also investigated. Extreme heterogeneity was observed among the species studied, with many cross-reactions due to common antigens, although species-specific antigens were also found in some cases. Occasional weak reactions were also demonstrated between certain clostridial antisera and the soluble antigens of three of the four species of Bacillus studied.
