title: [Regularities of the ubiquitous polyhostal microorganisms selection by the example of three taxa].
abstract: The investigation of the bacterial populations' heterogeneity contributes to the control of natural foci, causative agents of nosocomial infections, to the analysis of the microbial evolution. Multilocus sequence typing (MLST) was employed for the analysis of the diversity and features of the distribution of polyhostal ubiquitous microorganisms of the genera Burkholderia, Leptospira, and Listeria, which belong to three bacterial phyla: Proteobacteria, Spirochaetes, and Firmicutes. According to the bacterial samples analysis microbial genotypes prevalent and unique to Russia were identified; their occurrence in different Federal Regions was investigated; their similarity with global spread genotypes was appreciated. Obtained results allowed identifying common regularities of the selection of the microorganisms capable to cause the diseases of human and animals. The formation of genotypes that are most pathogenic for the host was demonstrated for all groups of bacteria. Leptospira spp. and Listeria monocytogenes strains with these genotypes have been circulating for a long time, being supported by natural foci. The formation of a wide variety of genotypes with different pathogenicity was demonstrated in the local geographic areas. In Russia, the zonal difference in all three groups of bacteria is most clearly traced to the Far Eastern Federal Region. The results are thought to contribute to analyzing the factors of selection and the phylogeny of the taxa under study.
