Description of strains of Peptostreptococcus anaerobius isolated from subcutaneous abscesses in cats.

Strains of Peptostreptococcus, Streptococcus and of a Gram-positive coccus, which was initially isolated as an anaerobe but grew subsequently as a facultative organism, were isolated from subcutaneous abscesses in cats. The cat strains of Peptostreptococcus gave metabolic fermentation products in combinations described for P. anaerobius. The Streptococcus strains conformed to the group S. intermedius. The facultative organism described had the metabolic products of P. anaerobius but the distinctly different biochemical characteristics of S. intermedius and fits neither of the genera strictly.
