Fig. 4From: Correlation between antimicrobial resistance, biofilm formation, and virulence determinants in uropathogenic Escherichia coli from Egyptian hospitalScatter plots representing the relationship between antibiotic resistance and the biofilm formation ability. Each of the tested 22 antibiotics is included, and the dotted line represents the cutoff for the biofilm formation categories: non-biofilm-forming strains (OD ≤ 0.1826), weak biofilm-forming strains (0.1826 ≥ OD ≤ 0.3652), moderate biofilm-forming strains (0.3652 ≥ OD ≤ 0.7305), and strong biofilm forming strains (OD ≥ 0.7305). Statistical significance at the P < 0.05, P < 0.01, and P < 0.001 levels are indicated by the symbols *, **, and ***, respectivelyBack to article page
