摘要 目的研究肺炎克雷伯菌的耐药性与毒力基因的分布及二者间的关系,为临床合理使用抗菌药物和控制感染提供依据。方法分离出172株肺炎克雷伯菌,采用纸片扩散法(K-B法)做药物敏感试验;聚合酶链反应(PCR)检测rmpA、aer-1、aer-2、magA、gyrB-2、ybt、wcaG毒力基因。结果 172株肺炎克雷伯菌分离株对头孢菌素类头孢唑啉、头孢呋辛、头孢噻肟与头孢曲松的耐药率分别为38.4%、34.9%、33.1%、32.0%。rmpA、aer-1、aer-2、magA、gyrB-2、ybt、wcaG毒力基因的阳性率分别为49.4%、55.8%、42.4%、16.3%、51.7%、53.5%、20.9%。肺炎克雷伯菌毒力基因分布与耐药性呈负相关,差异有统计学意义(P<0.01)。结论肺炎克雷伯菌毒力基因数与耐药性密切相关,临床应注意抗菌药物的合理应用,防止肺炎克雷伯菌耐药性的产生和传播。
