Fig. 3.

Level of agreement between antimicrobial resistance genes and phenotypic resistance for Escherichia coli; genes present with no antimicrobial resistance correspond to non-expression of antimicrobial resistance genes. Full black circles represent total agreement between phenotype and genotype. Half-black circles represent lesser antimicrobial resistance genes than the phenotype. Empty circles represent even lesser antimicrobial resistance genes. Quarter black circle in aminoglycosides represents about 20 per cent non-expression of antimicrobial resistance genes, and quarter black circles in tetracyclines represent lesser genotype and phenotype compared to total numbers.
