Gram-positive cocci, 0.8 µm in diameter, occuring in pairs or irregular clusters.
Non-motile. Non-spore-forming.

On Columbia agar supplemented with 5 % (v/v) horse serum after 72 h of incubation
in air, the colonies are 0.4-0.8 mm in diameter, semi-dry, semitransparent, circular,
raised and smooth. Growth occurs in NB and is facilitated by the addition of 5% (v/v)
horse serum. Optimal growth of the strain was observed at 37 ºC, pH 8.0 and 2%
NaCl (w/v) on Columbia agar. Growth is inhibited by 20% bile. Gamma-haemolysis is
visible on 5% (v/v) sheep blood agar and on Columbia blood agar with 5% (v/v) horse
blood. Can grow at 10-45 ºC and in 6.5% (w/v) NaCl. Facultatively anaerobic.
