An aerobic gram-positive coccus that produces either a yellow, orange, or cream- colored colony or an unpigmented gray-white or white colony. It produces free coagulase but not bound coagulase or hemolysins. It is part of the normal flora of the skin of pigs, the skin and milk of cattle, and from poultry. It is pathogenic for animals causing mastitis in cows and impetigo and septic polyarthritis in pigs. It is not considered as a pathogen for humans.
