title: [Estimation of the efficiency of ERIC-PCR typing of Mycobacterium tuberculosis for evaluation of the prevalence of antibiotic-resistant strains].
abstract: Twenty-four antibiotic-resistant and sensitive strains of M. tuberculosis isolated from different territories of the Irkutsk region (East Siberia) were studied using PCR genotyping by enterobacterial repetitive intergeneric consensus (ERIC). Evolution relationships are illustrated by phylogenetic trees as a result of analysis by UPGMA and ML approaches. It was found that the studied samples belonged to two genetically different groups, both of which included sensitive and resistant strains. The sensitivity of the method was calculated by the Hunter-Gaston index. Based on these data, a probable pattern of emergence and propagation of antibiotic-resistant forms of tuberculosis in the studied region is discussed.
