Clustering map of the SPI-7 region in representative S. enterica subsp. diarizonae genomes. TBLASTN searches, using the protein sequences from serovar Typhi strain CT-18 as query, were done to identify orthologous genes in S. bongori NCTC-12419, serovar Typhimurium SL1344 and 15 representative diarizonae genomes. Orthologous genes with 85% sequence coverage and 40% sequence identity were considered present and marked in blue. Orthologous genes that did not fulfil the criteria outlined above, were considered absent, and marked in white. The SPI-7 island of Typhi CT-18 strain and its different regions are depicted below of the clustering map
