Listeriosis: genotyping as a key for identification a possible source of infection

Objective. To perform a comparative analysis of clinical and food isolates of Listeria monocytogenes collected in the European part of Russia in 2018–2019. Materials and Methods. We used multilocus sequencing (MLST), supplemented by virulence loci, including fragments of internalin genes (MvLST, Multi-virulent-locus sequence typing), followed by phylogenetic analysis. Results. The main diagnoses for clinical isolates were prenatal and neonatal listeriosis and meningitis. Clinical isolates predominantly belonged to phylogenetic line II with the predominance of ST7, which was also the most abundant in food isolates.
