Gram-positive cocci, 0.7-0.8 μm diameter, nonmotile, nonsporing.
Colonies reach 1–1.5 mm in diameter after 24 hours and are circular, smooth, flat
with low-convex centres, glistening, white and have continuous margins. Weak
hemolysis. Facultatively anaerobic, optimum temperature 37 ºC ( can grow at 15 – 45
ºC). Media: Trypticase Soy Yeast extract Agar ± 5% sheep blood, Trypticase Soy Yeast
extract  Broth. Can grow on 12% NaCl agar.
Isolated from South American squirrel monkey - Saimiri sciureus L. (rectal swab & faeces). Sensible to novobiocin & lysostaphin.
Unknown. The eight strains isolated did not produce enterotoxins, although one strain was isolated from a monkey with diarrhoea
and rectal haemorrhage that died after 5 days.
