摘要
目的：了解泰州市人民医院2016年血培养病原菌的分布和耐药情况。方法：采用BACTEC ALERT 3D全自动血培养仪进行血培养；采用VITEK 2 Compact全自动鉴定系统进行微生物鉴定及药敏试验，链球菌药敏为纸片扩散法(K-B法)，真菌药敏采用DL-96 FUNGUS；WHONET5.6软件进行统计分析。结果：2016年全年血培养共检出病原菌380株，排列前5位的菌种依次为大肠埃希菌(24.2%)、表皮葡萄球菌(14.7%)、人葡萄球菌(12.1%)、肺炎克雷伯菌(8.7%)、金黄色葡萄球菌(7.9%)。血培养病原菌主要分布于：新生儿ICU(newborn-intensive care unit，NICU)、感染科、ICU、消化科。大肠埃希菌和肺炎克雷伯菌超广谱β-内酰胺酶(extended spectrum β lactamases，ESBLs)检出率分别为53.3%，33.3%。耐甲氧西林金黄色葡萄球菌(methicillin resistant Staphylococcus aureus，MRSA)检出率为44.4%，葡萄球菌未发现对利奈唑胺、万古霉素、奎奴普丁/达福普汀、替加环素耐药的菌株。结论：血培养病原菌在不同科室的分布和耐药性不同。

Abstract
Objective: To investigate the distribution and resistance of pathogens isolated from blood culture of patients in the Jiangsu Taizhou People’s Hospital in 2016. Methods: All blood samples were cultured by BACTEC ALERT 3D. Automatic detection machine of VITEK-2 Compact was used for identification of bacteria and fungus, as well as the susceptibility of non-fastidious bacteria. Susceptibility of streptococcus was tested by K-B method while susceptibility of fungus was tested by DL-96 FUNGUS. WHONET5.6 software was used for statistical analysis. Results: The total of pathogen strains isolated from blood culture in 2016 was 380. The top five bacteria were Escherichia coli (24.2%), Staphylococcus epidermidis (14.7%), Staphylococcus hominis (12.1%), Klebsiella pneumonia (8.7%), Streptococcus (7.9%). The pathogens of blood culture were mainly isolated from the department of newborn-intensive care unit (NICU), infection, ICU, gastroenterology dept. The resistance rates of Escherichia coli and Klebsiella pneumonia to extended spectrumβ lactamases (ESBLs) were 53.3%, 33.3%. Staphylococcus aureus had a 44.4% resistance rate to methicillin, while all of the three aureus were sensitive to linezolid, vancomycin, quinupristin/Dafoe leptin, tigecycline. Conclusion: Diversities of distribution and antimicrobial susceptibility of blood culture isolates are found in different clinical departments.
