Historical synonym:
Arthrobacter scleromae  Huang, Zhao, He, Wang, Liu, You and Guan 2005.
Gram-positive coryneform bacteria, with a rod-coccus cycle. Nonmotile. Spores are
not produced.
Colonies are  whitish, glistening, convex, smooth, up to 4-5 mm in diameter after 72 h
of incubation on blood agar or nutrient agar. Obligately aerobic. Grows at:  15-37 ºC;
no growth at 5 or 42 ºC. Can grow in 5% NaCl, but not in 10% NaCl.
Isolated from swollen scleromata of a dermatosis patient. Susceptible to ceftriaxone, chloramphenicol, rifampin, and tetracycline.
Resistant to amikacin, ampicillin, gentamicin, kanamycin, tobramycin, oxacillin, penicillin G, streptomycin, and norfloxacin.
Isolated from swollen scleromata of a dermatosis patient.

Some results are based on API Coryne tests (code 1042014).

Positive results for casein hydrolysis, catalase, DNA hydrolysis, esculin hydrolysis,
gelatin hydrolysis,  nitrate reduction (weak reaction), tyrosine hydrolysis, starch
hydrolysis, acid production from mannitol.

Negative results for beta-galactosidase, beta-glucuronidase, alpha-glucosidase, N-acetyl-beta-glucosaminidase, lipase, pyrrolidonyl
peptidase, urease, acid production from: glucose, glycogen, lactose, maltose, ribose, sucrose & xylose.
