Out of 1,597 cases of tuberculosis, culture positive for mycobacteria in 380 (24%) cases, of these 32 (8.4%) cases showed presence of anonymous mycobacteria. All these strains of the anonymous mycobacteria were isolated from patients of pulmonary tuberculosis. These include 3 photochromogens, 7 scotochromogens and 22 non chromogens. Photochromogens produced eugonic, rough, dry, granular and buff coloured growth, which on exposure to light formed deep yellow pigment. Optimum growth appeared on 37°C. These were neutral red positive, although poor cord former and strongly catalase positive.
