^aThis table lists genes in the Salmonella Pathogenicity islands (SPIs) 1 to 6
^bGenes in SPIs 1 to 5 are reported as described by [53] using primary annotation locus numbers for Salmonella Typhimurium LT2; genes in SPI-6 are reported as described by [54] using JCVI locus numbers for Salmonella Typhi CT18
