Abstract:  In the present study, two methods of DNA isolation-routine, traditional and standard DNA isolation protocol for Mycobacteria (Method 1) and a new non-chemicals and non-enzymes (physical) method (Method 2) of DNA recovery have been compared and evaluated in IS900 PCR for the specific detection of pathogen. Using the new Method 2, DNA has been recovered from few (1 – 3 colonies), extremely minute and stunted colonies. DNA, thus, isolated from these colonies (colonies PCR) and cultured for the first time from the cases of Crohn’s disease in human beings, dairy cattle, raw milk and pasteurized commercial milk samples has been characterized in the present study. It is the first report from India.
