Only the results for antimicrobial resistance genes that exhibited an association with another gene at a P level of <0.05 are shown. Significance level of association (as assessed by the chi-square exact test): −, P > 0.05; +, 0.05 ≥ P ≥ 0.01; ++, 0.01 ≥ P ≥ 0.001; +++, P ≤ 0.001. Parentheses indicate negative associations.
