Aim. Study of molecular-genetic properties of Shigella sonnei-2013 strain isolated during the outbreak in dysentery in the republic Abkhazia in 2013. Materials and methods. Genetic typing of the tested strains using multilocus sequence typing (MLST). Analyzed of nucleotide sequence fragments 7 of conservative «housekeeping» genes adk, fumC, icd, mdh, purA, recA, gyrB. Sequenced of DNA fragments compared with reference sequences from database of Escherichia coli MLST. Phylogenetic analysis was performed using UPGMA method and computer program START 2. Whole-genome sequencing performed on a genetic analyzer Ion Torrent Personal Genome Machine (PGM™) using fragment libraries (shot-gun). Aligning reads have been carried out with the program GS Reference Mapper. Results. Defined sequence - type of the studied strain - ST-152, one of the most common genotypes for S. sonnei.
