摘要
目的观察B族链球菌(GBS)检测试剂盒在GBS血流感染快速诊断中的应用价值。方法32例血培养阳性病例中分离出革兰阳性球菌,分别采用GBS胶体金免疫层析法检测试剂盒和全自动微生物鉴定系统鉴定GBS,评价GBS检测试剂的阳性预测值、阴性预测值和准确度。结果32株革兰阳性球菌中,GBS检测试剂和全自动微生物鉴定系统鉴定GBS 3例,GBS检测试剂的阳性预测值、阴性预测值和准确度均为100%。结论GBS胶体金免疫层析法可快速、简便检测GBS血流感染。
Objective To investigate the application value of group B streptococcus(GBS)detection kit in rapid diagnosis of bloodstream GBS infection.Methods Gram-positive cocci were isolated from 32 cases of positive blood cultures,of which GBS was determined by GBS detection kit(colloidal gold immunochromatography)and automated microbial identification system.The positive/negative predictive value and accuracy of GBS detection kit were evaluated.Results Among 32 strains of Gram-positive cocci,3 were identified by GBS detection kit and automated microbial identification system.The positive/negative predictive value and accuracy of GBS detection kit were 100%.Conclusion GBS colloidal gold immunochromatography is rapid and simple for detection of GBS bloodstream infection.
