Abstract: AIM: To explore the drug resistance reversing effect of Chinese herb simple substance plumbagin on baumanii. METHODS: Fifty-three strains of baumanii were isolated from patients. The antibacterial activities of 14 kinds of antibacterial drugs commonly used in clinic were detected. The direct antibacterial activities of Chinese herb monomer of plumbagin on standard strains were studied. After the determination of plumbagin and carbonyl cyanide m-chlorophenylhydrazone(CCCP) work concentration, the efflux inhibition test results of plumbagin and CCCP were compared.RESULTS: The resistance rate of 53 clinical isolates of baumanii to 14 kinds of clinical commonly used antimicrobial drugs was high.The ampicillin,cefazolin, cefuroxime, cefoxitin resistance rate was highest,respectively 100%,100%,98.1% and 98.1%. The rest of the drug-resistant rate is above 50%.The direct antimicrobial effect of plumbagin on quality standard bacteria was weak. Plumbagin and CCCP showed increasing sensitization to gentamicin, norfloxacin, minocycline hydrochloride and chloramphenicol. Their positive rates of efflux were 11.3% and 18.9%, 3.8% and 7.5%, 13.2% and 20.8%, 28.3% and 20.8%, respectively. There were no statistical differences between two groups.CONCLUSION: The clinical drug resistance of baumanii is in serious condition, and plumbagin as a kind of traditional Chinese medicine monomer may have a certain role in the drug resistance reversal.
