Gram- variable, motile (polar flagella) rods, 0.5-0.6 x 2.0-3.0 µm.  Spore is oval,
subterminally positioned, swelling the sporangium.
Colonies are colourless to white, translucent, mucoid on TSA. Alpha-haemolytic on
5% sheep blood agar. Aerobic and anerobic growth. Growth temperature 15-42 ºC,
optimum 30-37 ºC. Can grow in 0-3%, but not in 5% NaCl media. Optimum growth at
pH 7.
Isolated from human sputum. Susceptible to ampicillin, chloramphenicol, erythromycin, neomycin, penicillin G, rifampicin,
streptomycin, tetracycline, trimethoprim / sulfamethoxazole and vancomycin. Resistant to kanamycin.
The type strain was co-isolated from the sputum of a 60-year-old male patient during the screening of mycobacteria from patients with
nontuberculous pulmonary diseases.
