Cultural characteristics
Biochemical characters
Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Staphylococcaceae, Genus Staphylococcus,
- Staphylococcus schleiferi subsp. coagulans  Igimi et al. 1990
- Staphylococcus schleiferi subsp. schleiferi  Freney et al. 1988
Gram-positive cocci, 0.8-1.2 μm diameter, nonmotile, nonsporing.
Colonies are circular, S-type, opaque, nonpigmented. Facultatively anaerobic.
Optimum growth temperature 35-37 ºC. Growth media: Trypticase Soy Yeast extract
Agar ± 5% sheep blood, P agar, Trypticase Soy Yeast extract  Broth.
Subsp. schleiferi tolerates10% NaCl; growth on 15% NaCl delayed. Temperature
range for growth 20–45 ºC. Weakly hemolytic.
Subsp. coagulans is hemolytic; produces beta-hemolysin.
Isolated from human & animal (dogs) clinical samples - skin & ears. Novobiocin sensible (both subspecies).
Subsp. schleiferi: endocarditis in humans, nosocomial infections.
Subsp. coagulans: external otitis in dogs, pyoderma (also isolated from skin of healthy animals).
