Abstract:
OBJECTIVE To explore the relationship between multidrug resistance of Acinetobacter baumannii(ABA) and its class Ⅰ integron.METHODS In this study,39 multidrug resistant strains and 41 non-multidrug resistant strains of ABA were collected.The improved Kirby-Bauer was employed to check the collected strains′ drug-resistant phenotype;PCR was administrated to detect the distribution of class Ⅰ integron.and their relationship was also analyzed.RESULTS Results showed that ABA′s drug-resistance rate to the most antibiotics was high.imipenem,cefoperazone-sulbactam,ABA was sensitive to ciprofloxacin,amikacin and Piperacillin-tazobactam,however,ABA′s drug resistance rates to other antibiotics were all over 40%.It revealed that ABA′s drug-resistance rate was high.The study indicated that the positive rate of Class Ⅰ integron in multidrug resistant ABA was as hight as 82.1%(32/39).The positive rate of non-multidrug resistant strains was 26.8%(11/41),and the differences were statistically significant(?2=24.6,P
