Gram-positive pleomorphic (frequently swollen at one or both ends) rods, developing
coccoid forms in stationary cultures. Non-motile. Non-spore-forming. Mycolic acids
are produced. Tuberculostearic acid is present.

Colonies on trypto casein soy agar supplemented with Tween 80 are convex, whitish,
glistening with entire edges and 1 mm in diameter after 24-48 hours at 37 ºC.
Non-haemolytic. Facultatively anaerobic.

N-acetyl-beta-glucosaminidase, gelatin hydrolysis, hippurate hydrolysis, oxidase, lipase C14, pyrrolidonyl arylamidase, trypsin,
chymotrypsin, urease, acid production from: glycogen, inulin, lactose, mannitol, sorbitol, starch & xylose.
Variable results for acid phosphatase, alkaline phosphatase, cystine arylamidase, ester lipase (C8), leucine arylamidase, nitrate
reduction, valine arylamidase, acid production from: maltose, gluconate, N-acetyl-beta-glucosamine, sucrose & trehalose.
