Description is based on a single isolate.
Gram-positive irregular-shaped tapered rods and clubs. Mycolic acids are absent.
Nonspore-forming. Nonmotile.
Grows aerobically at 37 ºC on Columbia agar (Oxoid) supplemented with 5% sheep
blood: colonies were 0.5 mm in diameter after 24 h, increasing to 2 mm at 72 h, and
were circular, convex, entire, opaque and dull. Non-haemolytic. CAMP-negative. Can
grow at 22 and 42 ºC.
Isolated, in mixed culture  with Atopobacter phocae and Streptococcus dysgalactiae, from the penis of a Caspian seal (Phoca
caspica
). Habitat is not known.
Undetermined.

Non acid-fast. Fermentative metabolism. Most biochemical reactions were determined
by API ZYM and API Coryne tests.

Positive results for catalase, esterase C-4, esterase lipase C-8, pyrazinamidase, trypsin, urease, acid production from: glucose &
ribose.

Negative results for acid phosphatase, alkaline phosphatase, esculin hydrolysis, gelatin hydrolysis, beta-galactosidase,
alpha-glucosidase, beta-glucuronidase, lipophilism, nitrate reduction, oxidase, acid production from: glycogen, lactose, maltose,
mannitol, sucrose & xylose.
