Gram-positive diphtheroid, short and plump rods. Nonmotile. Spores are not
produced.
Colonies are opaque, glistening, greyish, smooth or sticky, 1-2 mm in diameter after
48 h / 37 ºC aerobically incubation on sheep blood agar.
Grows optimally at 37 ºC.
Can grow at 30
ºC, but not at 20 ºC.
Isolated from various human body sites (cerebrospinal fluid, a groin abscess, blood, a wound, intravascular catheter, a groin swab
and from an ear discharge)
.
The ecological niche is not known
.
Susceptible to penicillin, ampicillin, cefotaxime, cephalothin, erythromycin,
and vancomycin.
No pathological role was proved.
