  1. Phenotypes: 24°C, 36°C, 45°C: growth at temperature shown; pg: pigmentation (N, nonchromogen; P, photochromogen; S, scotochromogen); TCH: growth on thiophene-2-carboxylic acid hydrazide; nit: nitrate reduction; Tween: hydrolysis of Tween 80; NaCl: growth on 5% NaCl; Aryl 3. Aryl 15: arylsulfatase activity after 3 and 15 days of growth, respectively; ag: growth on nutrient agar; pic: growth on picric acid; β-gal: β-galactosidase activity; LJ: growth on Löwenstein-Jensen media; HA: growth on hydroxylamine 500 μg/ml; PNB: growth on p-nitrobenzoic acid; INH: isoniazid; RF: rifampicin; EMB: ethambutol; CIP: ciprofloxacin; OFL: ofloxacin. Responses are graded 0 (negative, no growth, no activity expressed) to 3 (positive, heavy growth, strong activity expressed); nd, not done. For patterns with multiple isolates, the result shown represents the most common phenotype(s) or the range of phenotypes observed.
