Heatmap of the SPI1-SPI5 regions in the S. enterica subsp. diarizonae genomes. TBLASTN searches, using the protein sequences from serovar Typhimurium SL1344 strain as query, were done to identify orthologous genes in S. bongori NCTC-12419, serovar Typhi CT-18, and 15 representative diarizonae genomes. Orthologous genes with 85% sequence coverage were considered present, and marked in blue. The color intensity represents the sequence identity from 50 to 100% (complete protein). Orthologous genes that did not fulfil the criteria outlined above, were considered absent, and marked in white. Phage remnants regions, SBO13 genomic islands (GI) and Salmonella pathogenic islands (SPI) are indicated in cyan, purple and dark blue, respectively
