Schematic representation of the repertoire and relative genomic location of fimbrial loci in the published genomes of S. enterica serovars. Each coloured box represents a distinct fimbrial locus encoded in the sense (top) or anti-sense (bottom) orientation. Boxes of the same colour on both strands represent divergently transcribed operons. A diagonal line through the box indicates that at least one gene in the operon is a predicted pseudogene. The repertoire of S. Typhimurium and S. Typhi is representative of other sequenced strains of the same serovar. All genomes are aligned relative to their predicted origin. Not to scale.
