摘要 目的:比较研究莫西沙星与其他12种抗菌药物对临床常见致病菌的体外抗菌活性.方法:采用琼脂平板二倍稀释法测定对411株临床分离菌株的最低抑菌浓度.结果:金黄色葡萄球菌(包括MRSA)和肺炎链球菌(包括PISP和PRSP)对万古霉素的敏感性最高,敏感率为95.8%~100%,对莫西沙星、加替沙星的敏感性较高,对大环内酯类药物则比较耐药.流感嗜血杆菌、卡他莫拉菌对莫西沙星、加替沙星等4种氟喹诺酮类和5种头孢菌素类及阿齐霉素比较敏感.肺炎克雷伯菌(包括产ESBLs菌株)对莫西沙星等4种氟喹诺酮类和头孢美唑很敏感;非产ESBLs菌株对8种抗菌药物均敏感,但产ES-BLs菌株对第二、三代头孢菌素则显示了较高的耐药率.大肠埃希菌(包括产ESBLs菌株)对氟喹诺酮类敏感率在40%左右,非产ESBLs菌株对5种头孢菌素均较敏感,但产ESBLs菌株除对头孢美唑敏感外,对其他头孢菌素类耐药率较高;结论:莫西沙星与其他12种抗菌药物比较,对革兰阳性菌(包括MRSA和PRSP)作用增强,对肺炎克雷伯菌(包括产ESBLs菌株)抗菌活性较强,大肠埃希菌对莫西沙星与其他氟喹诺酮类有一定的交叉耐药性.
