Acid-fast, pleomorphic rods. Long filamentous forms are often observed. No spores,
capsules or aerial hyphae are present. Gram-positive.
capsules or aerial hyphae are present. Gram-positive.
Colonies are mucoid, convex, round, entire edged. Grow on Lowenstein-Jensen
medium at 35 ºC in less than 7 days. Growth range 28-35 ºC. No growth at 42 ºC.
Colonies after incubation on heart infusion agar with 5% (v/v) rabbit blood for 2 days at
35 ºC are white to slightly beige, small-diameter (approx. 1 mm). Grows on 5% (w/v)
NaCl or on MacConkey agar without crystal violet. No growth in lysozyme.

The type strain was isolated from an antral sinus.

amoxycillin+clavulanate, ciprofloxacin, imipenem, sulfamethoxazole and trimethoprim+sulfamethoxazole.

Positive results for arylsulfatase (3 days), iron uptake, nitrate reduction, and urease. Acid is produced oxidatively from adonitol,
L-arabinose, i-erythritol, D-fructose, D-glucose, i-myo-inositol, Dmannitol, D-mannose, L-rhamnose, salicin, D-sorbitol and D-trehalose.
Can utilize acetamide, adonitol, L-arabinose, i-erythritol, D-fructose, D-glucose, i-myo-inositol, Dmannitol, D-mannose, L-rhamnose,
salicin, D-sorbitol and D-trehalose.
Negative results for semi-quantitative catalase test (foam below 45 mm) and thermostable catalase (68 ºC). Acid is not produced from
dulcitol, D-galactose, glycerol, lactose, maltose, melibiose, raffinose, starch, sucrose and D-xylose.
No utilization of citrate, cellobiose, dulcitol, D-galactose, glycerol, lactose, maltose, melibiose, raffinose, starch, sucrose and D-xylose.
