比阿培南对501株临床分离致病菌的体外抗菌活性研究

目的:评价比阿培南对501株临床分离致病菌的体外抗菌活性。方法:采用刃天青微孔板稀释法测定比阿培南和对照品(美罗培南、亚胺培南、头孢吡肟、头孢他啶、头孢哌酮/舒巴坦、环丙沙星、苯唑西林、万古霉素)对501株临床分离致病菌的体外抗菌活性。结果:比阿培南对大肠埃希菌、克雷伯菌属、产气肠杆菌、阴沟肠杆菌、志贺菌属、沙门菌属、变形杆菌属、沙雷菌属、柠檬酸菌属、不动杆菌属和铜绿假单胞菌的MIC50分别为0.06,0.13,0.25,0.13,0.03,0.03,1.00,0.50,0.13,0.13,0.50μg/mL;MIC90分别为0.13,0.13,0.50,0.50,0.03,0.06,1.00,0.50,0.25,0.25,4.00μg/mL。结论:比阿培南对临床分离致病菌的最低抑菌浓度MIC50、MIC90低于对照品。
