153株血培养病原菌的分布及耐药性分析

目的了解该院2014-2015年血培养中病原菌构成与耐药情况。方法对病房送检的1 260例血培养标本进行细菌培养,阳性标本进行分离鉴定及耐药情况分析。结果 1 260例血培养标本中分离出细菌153株,阳性率12.1%。病原菌中,革兰阴性杆菌以大肠埃希菌和肺炎克雷伯菌为主,革兰阳性球菌以凝固酶阴性葡萄球菌和金黄色葡萄球菌为主;肠杆菌科对亚胺培南、厄他培南的敏感度为100.0%,革兰阳性球菌对万古霉素、利奈唑胺和替加环素的敏感度为100.0%。结论血培养标本病原菌的耐药情况严重,及时监测病原菌变化及耐药趋势,指导临床合理用药非常重要。

Distribution and drug resistance of 153 pathogen strains in blood culture

Objective To investigate the distribution and drug resistance of pathogen in blood culture from 2014 to 2015.Meth-ods 1 260 blood specimens were incubated in our hospital,the positive samples were isolation and identification and the drug resist-ance was analyzed.Results 153 strains of bacteria were isolated from 1 260 blood specimens,and the positive rate was 12.1%. Escherichia coli and Klebsiella pneumonia were the main pathogens in gram negative bacilli,coagulase negative Staphylococci and Staphylococcus aureus were the main pathogens in gram positive cocci,Imipenem and ertapenem were the most effective antibiotics (100.0%)to Escherichia coli and Klebsiella pneumonia,the gram-positive cocci were sensitve to Vanconmycin,linezolid and tigecy-cline.Conclusion Drug resistance of isolated pathogen in blood cultures is very serious.Monitoring the change of pathogens and trends of drug resistance is very important in guiding the clinical use of drug.
