摘要 目的了解我院临床分离的流感嗜血杆菌、肺炎链球菌和卡他莫拉菌的耐药性。方法对2012年1月-2013年8月我院不同标本分离的流感嗜血杆菌、肺炎链球菌、卡他莫拉菌,依照CLSI2010版标准判断药敏结果 ,采用WHONET5.6软件进行数据处理和统计分析。结果2012年1月-2013年8月我院共分离流感嗜血杆菌60株(产β-内酰胺酶16株),肺炎链球菌60株、卡他莫拉菌43株(产β-内酰胺酶36株),除1株流感嗜血杆菌和4株肺炎链球菌自血液标本分离外,其他均来源于痰标本。流感嗜血杆菌对复方新渃明的耐药率最高60%,氨苄西林的耐药率为28.6%,对阿莫西林/克拉维酸、头孢噻肟、氧氟沙星敏感率均在90%以上。肺炎链球菌对红霉素、克林霉素、四环素耐药率分别为95.7%、95.5%、86.7%,对头孢噻肟、左氧氟沙星、青霉素的耐药率分别为0%、2.3%、8.5%。卡他莫拉菌对阿莫西林/克拉维酸、头孢呋辛、头孢克洛、头孢噻肟、氧氟沙星均呈现高度敏感(敏感率>90%)。结论流感嗜血杆菌和卡他莫拉菌对头孢菌素类、阿莫西林/克拉维酸以及喹诺酮类抗菌药物保持高度敏感性;产β-内酰胺酶仍是上述2种细菌对氨苄西林耐药的重要耐药机制;检出氨苄西林耐药而β-酰胺酶阴性的流感嗜血杆菌的分离株,其耐药机制有待进一步研究;肺炎链球菌对红霉素、克林霉素、四环素呈高水平耐药,头孢噻肟、左氧氟沙星、青霉素、阿莫西林是治疗肺炎链球菌所致感染的首选抗菌药物。对这些苛养菌造成的感染及其耐药性应当引起重视,临床应根据具体的药物敏感试验结果来指导用药,以减少耐药菌株的产生。
