[Analysis of the cytochrome P450 (CYP1A1) gene polymorphism in the ethnic groups of the Republic of Bashkortostan].

In three ethnic groups from the Republic of Bashkortostan, Russians (N = 451), Tatars (N= 333), and Bashkirs (N= 171), allele, genotype, and haplotype frequency distribution patterns of the CYP1A1 gene single nucleotide polymorphisms, A2455G and T33801C, were investigated. Substantial interethnic differences in the allele frequency distribution patterns of the CYPIA1 polymorphisms A2455G and T3801C (chi2 = 15.61, d.

[A contribution to the nomenclature and classification of chlamydiae].

The results of molecular-genetic study of typical specimens of the genus Chlamydophila of the family Chlamydiaceae from the FSE FCTRSA collection of microorganisms are considered for the purpose of their taxonomy based on comparative analysis by the omp1-, omp2-, 16S rRNA-, and 23S rRNA-genes and by the presence of extrachromosomal plasmid with corresponding fragments of the genomes officially registered species of chlamydiae. According to the omp1-RFLP-AluI-profile, the Rostinovo-70, 250, PP-87, and KC-93 strains were characterized by new genotype of chlamydiae (genotype G). The new omp2-RFLP-AluI-profile of chlamydiae on carrying out the comparative analysis of Rostinovo-70, 250, PP-87 and KC-93 strains by omp2-gene was characterized.
