Freney et al. 1988.
Gram-positive cocci, 0.8–1.0 μm in diameter, nonmotile, nonsporing.
Opaque (sometimes transparent or mixed), white-yellowish, S-type colonies. Small
area of beta haemolysis (weak).  Facultatively anaerobic,  growth temperature 37 ºC.
Temperature range for good growth 30–45 ºC; weak growth at 20 ºC. Tolerates 10%
NaCl; delayed growth on 15% NaCl. Media: Trypticase Soy Agar ± 5% sheep blood,
Trypticase Soy Broth, P agar.
Isolated from human  skin (perineal region mostly), abscesses, infected wounds, urine.
Susceptible to novobiocin and lysostaphin. Resistant to lysozyme and bacitracin.
Skin infections, brain abscess, sepsis, arthritis, urinary tract infections, chronic osteomyelitis & endocarditis reports (Staphylococcus
aureus
-like infections).
Prosthetic valve endocarditis, rarely native valve endocarditis.
Biofilm production (polysaccharide intercellular adhesin produced causing adhesion to prosthetic polymer devices).
