Abstract

Streptococcus pyogenes strains of emml 2 genotype, isolated from children in Saint-Petersburg in 2007, were investigated employing different molecular-genetic approaches. Smal restriction patterns of genomic DNA of the strains were analyzed. Distribution of the phage genes, including virulence genes and integrase genes, was studied. The significant genetic heterogeneity was observed. The transposon gene, which has not been previously discovered in S. pyogenes strains, was identified.
