Gram-positive, typical club-shaped rods that occur as single cells, in pairs or in
clusters. Nonspore-forming. Nonmotile.
Incubation at 37 ºC on sheep blood agar in a 5% CO2 -enriched atmosphere. CAMP
test is negative. Aerobic growth; not anaerobic.
Isolated from clinical specimens from dogs with otitis, pyoderma, interdigital cyst and vaginal infection. Its habitat is not known.
Isolated from clinical specimens from dogs with otitis, pyoderma, interdigital cyst and vaginal infection; the strains were recovered in
mixed culture with
Staphylococcus intermedius, Streptococcus canis, Proteus spp. or Malassezia pachydermatis.

No fermentative metabolism.
Most biochemical characters were tested on API Coryne and API ZYM.

Positive results for acid phosphatase, alkaline phosphatase, catalase, esterase
lipase (C8) (weak), hippurate hydrolysis, and acid production from glucose.

Negative results for gelatin hydrolysis, lipophilism, nitrate reduction, pyrazinamidase, starch hydrolysis, urease, Voges-Proskauer
reaction, acid production from: glycogen, lactose, maltose, sucrose, mannitol, ribose & xylose.

Esculin hydrolysis is variable.
