Abstract

In 1981, non-tuberculous mycobacteria (NTM) were obtained from 8.6 % of 16 907 sputum specimens in a trial in the Chingleput district of Madras state to test the efficacy of BCG vaccination in the prevention of tuberculosis, but from only 0.6 % of 672 autoclaved specimens cultured as part of a quality control procedure. This finding suggested that the NTM were truly derived from the sputum of the BCG trial subjects. The mycobacterial species could be identified in 966 (96.6 %) of the first 1000 isolates of NTM: 54.6 % were potential pathogens and 73.0 % were slow growing. The species isolated most frequently were M. avium/intracellulare (22.6 % of all NTM), M. terrae (12.5 %) and M. scrofulaceum (10.5 %). Those species accounting for 8–5 % of all NTM were M. fortuitum, M. chelonei, M. flavescens, M. gordonae and M. vaccae.
