CAMP and legionellosis: Within the second group of antibiotic resistance and virulence over-expressed KEGG pathways, 13 were reported, namely ABC transporters; Bacterial chemotaxis; β-Lactam resistance; Biofilm formation - Escherichia coli; Biosynthesis of ansamycins; Cationic antimicrobial peptide (CAMP) resistance; Legionellosis; Monobactam biosynthesis; Peptidoglycan biosynthesis; Phosphotransferase system (PTS); Protein export, Two-component system; and Vancomycin resistance (Figure 5B).
