Nucleotide comparison of SPI-6 from S. Typhi CT18, S. Typhimurium LT2 and S. Virchow SVQ1. Grey vertical blocks indicate regions of shared similarity shaded according to BLASTn. The coloured arrows represent genes. The functions of the genes have been inferred from BLAST searches. The intact SPI-6 in S. Typhi CT18 carries a Type VI secretion system (T6SS) and two fimbrial clusters (saf and tcf) and encodes the adhesin/invasin protein PagN. In S. Typhimurium LT2 the tcf fimbrial cluster is absent. In S. Virchow the T6SS is missing but both fimbrial clusters are present. The image was prepared using Easyfig [50].
