Description is based on a single isolate.
Gram-positive coryneform bacteria. Non-partially acid-fast. Non-spore-forming.
Colonies are white-greyish, convex, not lipophilic, 1.0 mm in diameter on Columbia
agar (Difco) supplemented with 5% horse blood after 72 h at 35 ºC in air plus 5%
CO2. CAMP test is positive. Facultative anaerobic.
Isolated from a wound swab from a human patient. Susceptible to cefotaxime, doxyxycline, erythromycin, linezolid, meropenem,
penicillin and vancomycin.
Isolated from a wound swab taken from an 89-year-old female patient.
