Epidemic multiple drug resistant Salmonella Typhimurium causing invasive disease in sub-Saharan Africa have a distinct genotype

Genes and homologous regions of pSLT-BT and pSKT-A130. A circular map of pSLT-BT shows predicted genes on the forward and reverse strands on the outer circle (yellow). Genes with putative antibiotic resistance functions (red), integron- or transposon-related functions (blue), plasmid-associated functions (green), antiseptic and mercury resistance functions (purple), miscellaneous functions (gray), and pseudogenes (brown) are shown. Arrows below the pSLT-BT composite element gene map indicate the annealing site of oligonucleotide primers used to probe clinical isolates. Regions of each locus with similarity to Tn21 are indicated.
