Development and evaluation of multilocus variable number tandem repeat analysis for fine typing and phylogenetic analysis of Salmonella enterica serovar Typhimurium.

Abstract excerpt

We identified 16 variable number tandem repeat (VNTR) loci for Salmonella enterica serovar Typhimurium. These VNTRs were evaluated with panels of 183 diverse isolates, 203 closely related isolates and 54 isolates from seven outbreaks. The evaluations revealed that five of the 16 VNTRs had diversity values greater than 0.5, and three (STTR5, STTR6 and STTR10) were hypervariable. The results obtained from the...
