The non-tuberculosis mycobacteria Mycobacterium avium subsp. hominissuis (MAH) are able to cause human mycobacteriosis. In this work, the results of the first comprehensive study of the genome polymorphism of the clinical strains of MAH were reported using the typing scheme by 13 loci MATR-VNTR (TR292, TRX3, TR25, TR47, MATR-1, MATR-4, MATR-5, MATR-6, MATR-8, MATR-11, MATR-14, MATR-15, MATR-16) containing tandem nucleotide sites and IS1245-RFLP-typing sites. A total of 90 MAH strains isolated from patients with lung mycobacteriosis without epidemiological connection (including HIV infected) were tested in 2008-2011. The inhomogeneity of the MAH strains by 36 profiles of 13 loci MATR-VNTR was observed. The majority of the strains (68.8%) were included in the 8 MATR-VNTR clusters; most large cluster contained 37 strains with 13-bitnumerical profile 2222223145443'. The nucleotide sequence of the MATR-16 (3') locus contains the long deletion (GenBank accession no. KF479191). The MAH strains of the MATR-VNTR clusters were found to be inhomogeneous by the IS1245 marker. The MATR-VNTR-typing method by 13 loci is recommended for preliminary differentiation of domestic MAH strains with further analysis of the MATR-VNTR clusters using the IS1245-RFLP-typing method.
