Genetic organization of the LEE islands and OI-122 identified in O145:H25 and other EHEC strains. tRNA integration sites are displayed on either sites and genes are colored based on functional characteristics as defined in the figure legend. Approximate sizes of the LEE and OI-122 are indicated in parentheses. Nucleotide sequences of the LEE and OI-122 were aligned in Geneious 9.1.5 using MAFFT with default settings. a Phylogeny and gene organization of the identified LEE islands. The maximum-likelihood tree was constructed in Geneious 9.1.5 using RAxML and the GTR + GAMMA + Invariable sites model and 500 bootstrap replicates. The scale bar indicates the number of substitutions per base; branch support values 1 representing 100. b Gene organization of OI-122 identified in the EHEC strains in comparison to the LEE-AR displayed above
