Acid-alcohol-fast rods.
Colonies can be either rough or smooth, and not pigmentated. Growth is observed
following incubation for 3-5 days at 30 ºC on Middlebrook 7H11 agar or egg slants.
Grows at 15-35 ºC; no growth at 4, 10, 37 or 40 ºC. No growth on Middlebrook 7H11
agar supplemented with picric acid. Very weak growth in the presence of 5% NaCl.

Isolated from thread-sail filefish (Stephanolepis cirrhifer) and black scraper (Thamnaconus modestus), in Japan.
Susceptible to clarithromycin (0.25 µg/ml), doxycycline (1 µg/ml) and ciprofloxacin (0.5-1 µg/ml); intermediate and/or resistant to
rifampicin, streptomycin, kanamycin and amikacin.

Positive results for thermo-stable catalase (68 ºC) and urease.
Negative results for arylsulfatase (3 days), semi-quantitative catalase, nitrate reductase, and Tween 80 hydrolysis.
Variable results for iron uptake.
