摘要: 目的:调查某院血流感染病原菌分布及其对抗菌药物的耐药情况,为临床合理使用抗菌药物和防控血流感染提供依据。方法:对该院2012年6月至2018年6月血培养分离的病原菌及药敏结果进行回顾性分析。结果:7 576份血培养标本共检出病原菌494株,阳性率为6.52%。菌株数位于前5位的细菌依次为肺炎克雷伯菌88株(17.8%)、大肠埃希菌84株(17.0%)、金黄色葡萄球菌61株(12.3%)、表皮葡萄球菌59株(11.9%)及粪肠球菌23株(4.7%)。其中检出革兰阴性杆菌276株(55.9%),革兰阳性球菌190株(38.4%),真菌28株(5.7%)。肠杆菌科细菌对美罗培南、亚胺培南、哌拉西林/他唑巴坦、头孢哌酮/舒巴坦(舒普深)的耐药率较低(1.2%~17.0%)。耐甲氧西林金黄色葡萄球菌(MRSA)和耐甲氧西林表皮葡萄球菌(MRSE)的检出率分别为57.4%和71.2%,主要革兰阳性球菌尚未发现耐呋喃妥因、利奈唑胺、万古霉素的菌株。血培养真菌分离率较高的为白假丝酵母菌(2.6%)及光滑假丝酵母菌(1.8%)。结论:该院近6年来血流感染病原菌以肠杆菌科细菌和葡萄球菌属为主。早期进行血培养病原学检查,重视对血培养病原菌进行耐药监测,有助于为血流感染临床诊断和治疗提供可靠依据。

Abstract: Objective: To investigate the distribution and drug resistance of pathogens causing bloodstream infections in hospitalized patients,and provide evidence for rational clinical use of antibiotics and control of healthcare-associated bloodstream infection. Methods:From June 2012 to June 2018,the pathogenic bacteria isolated from blood culture and antimicrobial susceptibility testing results in this hospital were analyzed retrospectively. Results: A total of 494 strains of pathogenic bacteria were isolated from 7 576 blood culture specimens,the positive rate was 6.52%. The top five pathogens were Klebsiella pneumoniae (n=88,17.8%),Escherichia coli(n=84,17.0%),Staphylococcus aureus(n=61,12.3%), Staphylococcus epidermidis(n=59,11.9%)and Enterococcus faecalis(n=23,4.7%),including 276 gram negative bacilli(55.9%),190 gram positive cocci(38.5%), and 28 fungus(5.7%).The resistant rates of enterobacteriaceae bacteria to meropenem,imipenem,piperacillin/tazobactam and cefopemzone/sulbactam were relatively low(1.2%-17.0%). The detection rate of methicillin-resistant S. aureus(MRSA) and methicillin-resistant S. epidermidis(MRSE) were 57.4% and 71.2% respectively. There were no strains of main gram-positive bacteria that were found to be resistant to macrodantin、 linezolid and vancomycin.The most common fungus in blood culture were Candida albicans(2.6%)and Candida glabrata(1.8%).Conclusion: Enterobacteriaceae and staphylococcus spp. are the main pathogens causing bloodstream infection in this hospital in recent six years. Early blood culture and surveillance on drug-resistant pathogenic isolates can provide reliable evidence for clinical diagnosis and treatment of bloodstream infection.
