【摘要】 目的调查医院感染病原菌的分布和耐药性,为控制医院感染提供依据。方法对医院2006年1月-2007年12月,培养分离出的519株医院感染病原菌的分布和耐药性进行统计和分析。结果检出G+球菌209株(40.27%),G-杆菌256株(49.33%),真菌54株(10.40%),其中G-杆菌逐年增高;G+球菌以金黄色葡萄球菌为主(15.99%);G-杆菌以不动杆菌属(13.29%)、大肠埃希菌(11.37%)、其他肠杆菌(7.13%)和铜绿假单胞菌(6.74%)为主。结论医院感染菌中G-杆菌呈逐年增高趋势,临床应根据病情及时做病原菌检测,结合药敏试验结果,正确合理使用抗菌药物。更多还原

【Abstract】 OBJECTIVE To investigate the drug resistance and distribution of nosocomial infection (NI) pathogens. METHODS A total of 519 strains of NI pathogens during from Jan 2006 to Dec 2007 were completely surveyed. RESULTS Among all pathogens,Gram-positive cocci were 209 strains (40.27%),the main pathogen was Staphylococcus aureus. Gram-negative bacilli were 256 strains (49.33%). Fungi were 54 strains (8.28%). resistance the rate in nosocomial infectionis was increased year by year. CONCLUSIONS The Gram-negatives of NI pathogens are markedly increased year by year. The drug resistance rate of pathogens is higher and the clinically selected anti-bacterial drugs should be based on the bacterial culture and drug susceptibility test.更多还原
