Gram-positive coryneform bacteria, mainly coccoid cells after 72 hours of incubation;
jointed rods are observed after 1-2 days of incubation. Nonmotile. Spores are not
produced.
jointed rods are observed after 1-2 days of incubation. Nonmotile. Spores are not

Colonies are convex, smooth, whitish-grayish, larger than 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 brevibacter.

Isolated from human clinical specimens (blood culture). Multiresistant, susceptible to tetracycline, teicoplanin and vancomycin.
Undetermined. Isolated from cultures of human blood.
