One hundred of mycobacterium cultures were assayed by the method of PCR with subsequent sequencing of the 16S rRNA region. The below mycobacterium species were identified: M. tuberculosis complex (n = 55), M. avium (n = 17), M. intracellulare (n = 4), M. scrofaleceum (n = 2), M. kansasii - M. gastri (n = 3), M. gordonae (n = 3), M. ulcerans - M. marinum (n = 1), M. smegmatis (m = 2), M. fortuitum (n = 11), M. peregrinum (n = 1) and M. chelonae - M. abscessus (n = 1). The method enabled the differentiation of species M. avium from M. intracellulare and M. peregrinum from M. fortuitum, which could not be differentiated by using the classic biochemical and bacteriological methods. Genetic heterogeneity of the mycobacterium strains of M. avium, M. fortuitum and M. gordonae was also established by PCR plus sequencing of the 16S rRNA region.
