【摘要】：目的了解血培养阳性标本的菌群分布及报阳时间,为实验室病原菌诊断及临床制定治疗方案提供依据。方法收集2015年5—11月某院临床各科室送检的血标本,记录血培养报阳时间并将所获得病原菌鉴定至菌种。结果从血培养标本中共分离157株病原菌,其中革兰阳性球菌占31.85%,革兰阴性杆菌占57.32%,真菌占10.83%。培养阳性病原菌及其报阳的中位时间分别为:肠杆菌科细菌0.50 d,非发酵菌0.63 d,肠球菌属0.60 d,链球菌属0.80 d,葡萄球菌属1.01 d,真菌1.44 d。结论血培养阳性标本报阳时间从早到晚依次是:肠杆菌科细菌、肠球菌属、非发酵菌属、链球菌属、葡萄球菌属、真菌。引起血流感染的病原菌均在4 d内仪器阳性报警,大多数病原菌在1 d内报阳性。
[Abstract]:Objective to investigate the distribution of bacteria and the time of positive blood culture in order to provide evidence for the diagnosis of pathogenic bacteria in laboratory and clinical treatment. Methods Blood samples were collected from clinical departments in a hospital from May to November, 2015. The time of blood culture was recorded and the pathogen was identified into bacteria. Results 157 strains of pathogenic bacteria were isolated from blood culture specimens. Gram-positive cocci accounted for 31.855.Gram negative bacilli accounted for 57.320.Fungi accounted for 10.83. The median time of culture positive pathogenic bacteria and positive bacteria was 0.50 days for Enterobacteriaceae, 0.63 d for non-fermentative bacteria, 0.60 d for Enterococcus, 0.80 d for Streptococcus, 1.01 d for Staphylococcus and 1.44 d for fungi. Conclusion the positive blood culture time from morning to night is Enterobacteriaceae, Enterococcus, Non-fermentative bacteria, Streptococcus, Staphylococcus, Fungi. The pathogens causing blood flow infection were positive within 4 days, and most of them were positive within 1 day.
