Abstract excerpt
Salmonella enterica serovar Typhi is a clone with a low level of variation. We developed a molecular typing method for serovar Typhi using 38 genome-wide single-nucleotide polymorphisms (SNPs) as markers detected by PCR-restriction enzyme digestion. The 73 worldwide serovar Typhi isolates studied were separated into 23 SNP profiles and four distinct genetic groups. Serovar Typhi isolates expressing the unique...
