Gram-positive, pleomorphic rods, arranged in palisades or V-shaped forms.
Nonmotile. Nonspore-forming.
Colonies are circular, slightly convex, smooth, with a creamy consistency, 1.0-2.0 mm
in diameter after 48 h of aerobically incubation at 37 ºC on Columbia blood agar.
Nonhaemolytic. CAMP test is positive. Facultatively anaerobic, slight growth under
anaerobic conditions.
Isolated from sheep milk.
Isolated from the milk of sheep affected by subclinical mastitis.

Fermentative metabolism.
Most biochemical characters were tested on API Coryne and API ZYM.

Positive results for alkaline phosphatase, catalase, esterase (C4), esterase lipase (C8), lipase (C14), pyrazinamidase and weak acid
production from glucose.

Negative results for acid phosphatase, chymotrypsin activity, esculin hydrolysis, gelatin hydrolysis, beta-glucuronidase, indole
production, lipophilism, nitrate reduction, oxidase, urease, Voges-Proskauer reaction, acid production from: glycogen, lactose,
maltose, mannitol, ribose, sucrose & xylose.
