Bel et al. 2013.
Description is based on a single isolate.
Gram-positive cocci, 0.5-0.8 μm in diameter, occuring singly, in pairs or in clusters.
Colonies on 5% sheep blood agar are white, glossy, circular, regular, bulged,
non-haemolytic and 1-3 mm in diameter after 48 h incubation at 37 ºC. The
temperature range for growth is 25-45 ºC, with optimum growth between 30 ºC and 37
ºC. Grows at 37 ºC in TSB containing 0-15 % (w/v) NaCl. Facultatively anaerobic;
grows better aerobically.
Isolated from a human brain abscess. Sensitive to novobiocin, oxacillin, gentamicin, clindamycin, ofloxacin, rifampicin, fosfomycin,
vancomycin, teicoplanin and trimethoprim+sulfamethoxazole. Intermediate susceptibility to fusidic acid.
Undetermined. Isolated from a human brain abscess.
