GI coordinates are based on islands obtained after recursive segmentation and agglomerative clustering. Novel predictions have been highlighted. Phylogenetic support is based on BLAST analysis. Unusual phyletic pattern, indicating a recent island transfer into the LESB58 strain, was determined by examining the distributions of the LESB58 island borne genes in the genomes of P. aeruginosa strains. The distribution of a gene was considered unusual or atypical if the majority of the LESB58’s close relatives (other P. aeruginosa strains) do not carry it. ∗Previously reported LESB58 islands not predicted by GEMINI. ∗∗LESB58 islands showing unusual phyletic pattern.
