- Abstract
Mycobacteria isolated from the environment are generally known as environmental mycobacteria, Atypical mycobacteria or Non-Tuberculous mycobacteria (NTM). They exist as saprophytes in all natural ecosystems and are known to be associated with human diseases especially in the immunocompromised individuals. Due to their great diversity and ubiquity, identification of NTM at the species level is very important especially when treatment options are about to start. In this study we made an attempt to isolate and characterize NTM from environmental samples such as soil and water collected from different areas in Kanpur, India. Environmental samples were decontaminated with NaOH and SDS and further incubated.Out of the 50 samples collected, only 20.4% NTM were recovered. The mycobacterial isolates were identified by the growth characteristics, including colony morphology, growth at 25°C, 37°C and 42°C, pigment production, semi-quantitative catalase test, Tween 80 hydrolysis, heat-stable catalase (pH 7, 68°C), nitrate reduction test. However, it is important to isolate NTM in large numbers to study its prevalence in and around the world.
