The two chromosomes, large (Chr. 1) and small (Chr. 2), are depicted. From the outside inward: the first and second circles show predicted protein-coding regions on the plus and minus strands. Colours correspond to the main classes of genes. Black denotes hypothetical proteins including both conserved and non-conserved in other bacteria. Ther third circle shows transposon-related (black), phage-related (blue), super-integron (pink), flagella-related (green) and pathogenesis-related (including pili and adhesins)(red) genes. The fourth circle shows GC skew. The fifth circle shows percentage G+C in relation to mean G+C for the chromosome. The sixth and seventh circles are rRNA and tRNA, respectively.
