ABSTRACT Forty strains of Staphylococci from infections of dogs and cats were characterized with respect to their coagulase and thermonuclease activities, and 19 strains for their fermentation of mannitol anaerobically. Thermonuclease correlated well with tube coagulase activity but there was a poor correlation between these two characters, the ability to ferment mannitol anaerobically, and the presence of bound coagulase. Fifty percent of the organisms were resistant to penicillin due to the presence of β‐lactamase (penicillinase). There was a strict correlation between detection of β‐lactamase by the disc diffusion and the slide penicillinase tests. Antibiotics to which organisms were resistant also were bacitracin (52·5%), lincomycin (20%), streptomycin (17·5%), tetracyclines (12·5%) and chloramphenicol (7·5%).
