摘要
目的:评价盐酸加替沙星(gatifloxacin)对临床分离的1222株致病菌的体外抗菌作用,并与盐酸环丙沙星、氧氟沙星、司帕沙星等进行比较。结果:盐酸加替沙星对大多数革兰阴性杆菌的MIC90值均低于0.5mg·L-1,抗菌作用与盐酸环丙沙星相似;对肺炎克雷伯杆菌、阴沟肠杆菌、变形杆菌、志贺菌的MIC90值分别为0.062,0.062,0.5,0.25mg·L-1;盐酸加替沙星对大肠杆菌的MIC90值为8mg·L-1,耐药率为58%,对盐酸环丙沙星耐药的大肠杆菌对盐酸加替沙星也耐药,存在着交叉耐药性。盐酸加替沙星对乙酸钙不动杆菌MIC90值为0.062mg·L-;铜绿假单胞和窄食黄单胞菌的MIC90值分别为2和1mg·L-1,与盐酸环丙沙星相同。盐酸加替沙星对革兰阳性球菌的抗菌作用比盐酸环丙沙星与氧氟沙星增强,对甲氧西林敏感的金葡菌、化脓性链球菌和肺炎链球菌MIC90值分别为0.125、0.125和0.5mg·L-1,与司帕沙星相同;对甲氧西林耐药的金葡菌盐酸加替沙星的MIC90值为4mg·L-1;对表皮葡葡菌MIC90值0.5mg·L-1;流感嗜血杆菌对盐酸加替沙星高度敏感,MIC90值为0.016mg·
