- A total of 308 raw milk samples, 209 from an organized farm and 99 from a market source, were examined for the presence of mycobacteria. Mycobacteria were recovered from 4.3% of the farm samples and from 5.1% of the market samples. The isolated cultures identified on the basis of morphological and physiological characteristics and virulence included Mycobacterium tuberculosis (bovine and human strains), M. phlei, M. kansasii, M. fortuitum, M. aquae and M. intracellulare. The significance of presence of even a few virulent strains of mycobacteria in raw milk is discussed.
