Table 5 The association between the minimum inhibitory concentrations and blaOXA carbapenemase genes of 154 isolates that were resistant to imipenem and meropenem

From: Study of genetic diversity, biofilm formation, and detection of Carbapenemase, MBL, ESBL, and tetracycline resistance genes in multidrug-resistant Acinetobacter baumannii isolated from burn wound infections in Iran
