Gram-positive coryneform bacteria without irregular branching, mainly coccoid cells
after 72 h of incubation. Nonmotile. Spores are not produced.
after 72 h of incubation. Nonmotile. Spores are not produced.
Colonies are slightly convex, smooth, creamy or sticky consistency, whitish-grayish,
up to 2 mm in diameter and slightly glistening after 24 h of incubation at 37 ºC in 5%
CO2 atmosphere on 5% sheep blood Columbia agar. Obligate aerobic. Does not
express a cheese-like smell, as observed for the phenotypically closely related
brevibacteria. CAMP test negative.

Isolated from human clinical specimens (urinary tract infections, skin infections, otitis, blood culture, infected amniotic fluid).
The MICs of penicillin are low and aminoglycosides and quinolones show weak activities; susceptible to glycopeptide antibiotics.
