Gram-positive cocci, 0.6-1.4 μm diameter, nonmotile, nonsporing.
Colonies are circular, slightly convex, S-type, pale orange pigmented, 4-9 mm in
diameter. Uniform turbidity in broth cultures followed by clearing with a fine or slightly
mucoid deposit. Facultatively anaerobic, 10–40 ºC, optimum 28–35 ºC. Media:
Trypticase Soy Yeast extract Agar ± 5% sheep blood, P agar, Trypticase Soy Yeast
extract  Broth.
Isolated from skin & urine samples (subsp. saprophyticus) and from upper respiratory tract of healthy cows (subsp. bovis).
Present in air, soil, dust, dairy products and surface of animal carcasses. Resistant to novobiocin and lysozyme. Sensible to
lysostaphin.
Subspecies bovis - unknown (none).
Subspecies saprophyticus - urinary tract infections especially in young women. Virulence factors: adherence to uroepithelial cells,
production of a hemagglutinin, production of extracellular slime.
