Investigation of integron gene cassettes in trimethoprim-sulfamethoxazole-resistant Acinetobacter baumannii isolates

Despite the low integron detection in the resistant isolates, with the detection of class I and class II integrons among A. baumannii isolates, it was determined that HAIs could spread very rapidly within the hospital and cause multidrug resistance. This study reveals the need for comprehensive surveillance and molecular characterization of integron-mediated resistance mechanisms to inform effective strategies to combat infections caused by multidrug-resistant (MDR) A. baumannii.
