我院2006～2008年病原菌分布及其耐药性结果分析

目的了解病原菌的变迁和耐药性,指导抗菌药物合理使用。方法回顾性分析2006～2008年的病原菌及其耐药性。结果3632株病原菌中革兰阴性菌1813株占50%、革兰阳性菌473株占13%、真菌1346株占37%。3年来,医院感染病原菌G-杆菌增加,G+球菌不变,真菌感染有逐年降低趋势。位于前3位的革兰阴性菌和革兰阳性菌分别是大肠埃希菌、铜绿假单胞菌、鲍曼不动杆菌和金黄色葡萄球菌、凝固酶阴性葡萄球菌、屎肠球菌。碳青酶烯类仍是对革兰阴性菌抗菌作用最强的一类抗菌药物。未发现耐万古霉素的葡萄球菌和屎肠球菌。结论加强病原菌的感染监控,及时提供医院感染菌株流行情况及其耐药率变迁信息。为合理使用抗菌药物提供依据。

Distribution and Drug Resistance of Pathogenic Bacteria Causing Hospital Nosocomial Infection Between 2006 and 2008 in Our Hospital

Objective To observe bacterial changing-pattern and drug-resistant pattern for reasonable application of antibiotics.Methods We reviewed the data of 2006~2008 pathogens tests.Results Of 3632 isolated pathogens,1813(50%)were Gram-negative bacilli,473(13%)were Gram-positive cocci and 1346(37%)were fungi.Over the 3 years,Gram-negative bacilliin strains causing hospital nosocomial infections increased,Gram-positive cocci strains remain stable,but fungous infection showed a decline tendency.The most common Gram-...
