Acid-alcohol-fast, curved rods. Gram-positive. Non-spore-forming.
Colonies are usually smooth, off-white in color, mucoid, and non-pigmented. The
temperature range for growth is 28-37 ºC; does not grow at 42 or 45 ºC. Growth
appears on Middlebrook 7H10 and trypticase soy agars in 2-4 days. Grows on
MacConkey agar without crystal violet (sometimes weakly or not growing) , but not on
agar supplemented with 5% (w/v) NaCl.

Isolated from outbreaks of peritonitis associated with automated peritoneal dialysis machines and water. Susceptible to amikacin,
imipenem, cefoxitin, clarithromycin, and ciprofloxacin. Resistant to isoniazid and rifampin.

Positive results for arylsulfatase (3 and 14 days), esculin hydrolysis, pyrazinamidase, tellurite reduction, Tween 80 hydrolysis, and
urease.
Can utilize as sole carbon source D-mannitol and citrate (most strains).
Negative results for arginine dihydrolase, catalase (semi-quantitative) (most strains), heat-stable catalase, beta-galactosidase,
alpha-glucosidase, beta-glucuronidase, gelatinase, H2S production, indole production, iron uptake, lysine decarboxylase, ornithine
decarboxylase and tryptophan deaminase.
No utilization of i-myo-inositol and sorbitol as sole carbon sources.
Variable results for nitrate reduction.
