Based on the phylogenetic tree, genome of LYSZa7 was compared with selected species including PAO1 reference strain and virulent clinical strains, PA14, PA 34, DK2, and Pa1207 isolated from patients with different diseases like cystic fibrosis, keratitis, and bacteremia to predict specific genomic islands (GIs) on LYSZa7 genome (Figure 4). Here, SMOX is linked to keratitis.
