ELLNER AND STANLEY S. GREEN Department of Medical Microbiology, College of Medicine, University of Vermont, Burlington, Vermont Received for publication 15 April 1963 The problem of whether Clostridium sordellii should be assigned species status or be retained as a pathogenic variant of C. bifermentans is a perplexing one. Despite marked similarities in morphology, colony formation, and biochemical reactions (Clark and Hall, J. Bacteriol. 33:23, 1937; Stewart, J. Bacteriol. 35:13, 1938), Brooks and Epps (J. Gen. Microbiol. 21:144, 1958) were able to distinguish between strains of C. bifermentans which were urease-negative and non- all strains (Fig. 2 and 3). Although pathogenicity tests clearly distinguished between P and NP strains of C. sordellii, no antigenic differences could be detected. WVhen antigen pools representing either C. sordellii or C. bifermentans were tested against both homologous and heterologous sera, it became apparent that four antigens were common to both species.
