ABSTRACT: Five hundred and seventy four clinical samples from patients in and around Varanasi with suspected pulmonary and extra-pulmonary tuberculosis were processed for isolation of mycobacteria. Fifty isolates were identified to species level using morphological and biochemical characteristics. Forty six (92 percent) were identified as M.tuberculosis, two (4 percent) as M. scrofulaceum and one each (2 percent) as M.kansasii and M. vaccae. Among 46 M tuberculosis isolates, two (4.3 percent) were niacin negative variants of human tubercle bacilli. (178-179)
