Molecular determinants of virulence genes of Salmonella Enteritidis prevailing in Armenia Biology

Abstract

The main goal of this study was to establish genetic heterogeneity of virulence genes of Salmonella enterica serovar, which causes salmonellosis with different clinical presentation. With the use of PCR screening the prevalence of virulence genes located on pathogenicity islands and plasmid-encoded virulence factors were revealed. The results indicate about genetic heterogeneity of spv-operon genes of S. Enteritidis clinical isolates.
