“…They also observed that animals protected with C. bifermentans antiserum resisted infection with C. sordellii. Studies by McCoy and McClung (1938) indicated that crossagglutination occurs among some species of clostridia, and serological investigations of individual or small groups of species of clostridia have also been done (Coleman and Gunnison, 1928;Gunnison, 1937Gunnison, , 1947Smith, 1937;Miles, 1947, 1950;Oakley, Warrack, and Clarke, 1947;Mandia and Bruner, 1951). Double diffusion in agar gel was utilized by Bjorkland and Berengo (1954) to study the interactions of seven species of clostridia.…”

“…Serological results do not always confirm biochemical patterns. McCoy and McClung (1938) emphasized that serological results are not always in harmony with present taxonomic schemes. Since serolological tests must eventually be combined with the biochemical reactions commdnly used in order to adequately describe bacterial species, it is desirable that further studies be carried out along this line.…”

SUMMARY Under anaerobic culture conditions, 120 cultures of sporeforming rods were isolated from fresh and cured pork trimmings and from pork luncheon meat; 22 of these proved to be obligate anaerobic putrefactive organisms. Studied by the Reed and Orr method of rapid identification, the following species were identified: Clostridium. tetanomorphum, Cl. novyi, Cl. carnis, Cl. paraputrificum, Cl. tetani, Cl. histolyticum, and Cl. sporogenes. One culture was similar to Clostridium sp. National Canners Association putrefactive anaerobe 3679 (PA 3679). Serological relationships were determined by using antisera for Cl. sporogenes and PA 3679. No cross agglutination was obtained between Cl. sporogenes and PA 3679. An organism identified biochemically as Cl. carnis agglutinated in dilutions of 1:5120 of PA 3679 antiserum, indicating a very close serological relationship. Several organisms revealed antigens in common with Cl. sporogenes. The organism with biochemical reactions similar to PA 3679 showed no serological relationship to the known species. Serological relationships correlated with heat resistance while biochemical reactions did not.

Trimethylsilyl (TMS) derivatives prepared from whole-cell hydrolysates of 36 strains, representing 10 species of Clostridium were examined by gas-liquid chromatography (GLC). The TMS profile of each species contained a group of peaks which characterized the species. Variation among strains within a species was much lower than variation between species. Some of the closely related clostridia could be differentiated by comparing their TMS profiles. Strains of Clcstridium botulinum were distinguished from C. sporogenes on the basis of the ratio of two GLC peaks which corresponded to arabinose and glucose. A peak with a retention time identical to that of mannose was present in all C. bifermentans strains but was absent in those of C. sordellii. The genus Clostridium is composed of a very heterogeneous group of organisms which are gram-positive, anaerobic, catalase-negative, spore-forming rods. Some species of this genus fix atmospheric nitrogen, some are thermophilic, and others are pathogenic for man and animals. Various approaches have been used to study this diverse group of bacteria. Biochemical tests 55 C under a gentle stream of nitrogen. The residue was dissolved in 10 ml of hexane, and the volume was reduced to 0.25 ml under nitrogen. Reference sugar samples obtained from Sigma Chemical Co., St. Louis, Mo., were processed by the same procedure. 78
