The obligatory human pathogen, Mycobacterium tuberculosis, is the most important etiological factor of tuberculosis. Unfortunately, there is little information about genetic diversity of this pathogen. The main aim of this research was the estimation of genetic diversity of M. tuberculosis on the basis of various categories of DNA markers. The genome of 32 strains were scanned by DNA markers such RAPD, IS6110 and catalase-peroxidase katG gene. All 162 identified loci were polymorphic. The genetic diversity coefficient (HT) of M. tuberculosis was 0.32 for RAPD and 0.27 for IS6110. There were 14 alleles in katG gene. All strains were characterised by the individual molecular pattern. Genetic similarity varied from 0.13 to 0.94 (RAPD markers) and from 0 to 1 for (IS6110). M. tuberculosis strains did not represent a clonal structure, single source of transmission and epidemiological relationships as well. The applied DNA markers proved to be highly efficient for analysis of genetic structure of M. tuberculosis.
