Description is based on a single isolate.
Gram-positive coryneform (club-shaped) bacteria arranged in single cells, clusters or
filamentous rods (more than 15 µm in length); some cells exhibited branching.
Nonspore-forming. Nonmotile.
Colonies are domed and adherent to agar, beige-whitish, dryish with  irregular
margins, convoluted, 1.0-2.0 mm in diameter after 48 h of incubation at 37 ºC on
Columbia sheep blood agar. CAMP reaction is negative. Facultatively anaerobic.
Isolated from a patient’s wound caused by a dog bite. Susceptible to cefotaxime,  ciprofloxacin, doxycycline, erythromycin, gentamicin,
linezolid, meropenem, penicillin, rifampicin, vancomycin and vibriocidal compound O/129.
Undetermined.
