摘要: 目的 观察克拉霉素与加替沙星联用对大鼠铜绿假单胞菌生物被膜肺部感染的治疗作用。方法 建立铜绿假单胞菌生物被膜慢性肺感染的大鼠病理模型,应用克拉霉素(100mg·kg-1)、加替沙星(25mg·kg-1)单独或联合治疗,观察感染症状、病理、细菌学以及免疫学变化。结果 克拉霉素与加替沙星联合治疗2 wk 后,可基本清除生物被膜感染肺内细菌,血清抗菌抗体接近正常,病理以修复期改变为主。结论 克拉霉素与加替沙星联合应用对铜绿假单胞菌生物被膜感染治疗作用明显。

Abstract: AIM: To investigate the combined effects of clarithromycin and gatifloxacin on experimentalPneumonia withPseudomonas aeruginosa in rats as a model for biofilm-associated infection.METHODS: The rat models of biofilm associatedPulmonary infection were created,and then were divided into 4 groups:models,clarithromycin(100mg·kg-1),gatifloxacin(25mg·kg-1),and clarithromycin(100mg·kg-1)+gatifloxacin(25mg·kg-1).The changes ofPathology,bacteriology and immunology were observed.RESULTS: After the treatment of clarithromycin combined with gatifloxacin,the bacterium inlung were almost cleaned,and the antibody in serum to bacteria returned to normal.The changes ofPathology were restored.CONCLUSION: The combination of clarithromycin andlevofloxacin has synergism in treating biofilm-associated chronic respiratory infection in animal models.
