Abstract:
OBJECTIVE: To investigate the resistance phenotype of acinetobacter baumannii and the expression of ade efflux pump gene. METHODS: Non-repetitive 51 strains of Acinetobacter baumannii were collected in Peking Union Medical Hospital between Feb. 2004 and Feb. 2005. The active efflux system adeB structural gene and sequence were identified by PCR. RESULTS: The tested strains were not susceptible to common broad-spectrum antibiotics. Multidrug resistant Acinetobacter baumannii carried adeB active efflux pump gene. CONCLUSION: The multiple-drug resistance of Acinetobacter baumannii is independent of ?-lactamase. It maybe related to other drug resistance mechanism. The effect of active efflux system is possibly one of the major mechanisms of multidrug resistance of acinetobacter baumannii.
