伤寒杆菌H抗原检测、肥达反应与细菌培养对伤寒诊断的对照观察

Contrast observation on typhoid bacilli H antigen detection, widal reaction and bacterial culture for diagnosing typhoid

目的 提高伤寒患者的诊断阳性符合率。方法 该文采用细菌培养、肥达反应、伤寒杆菌H抗原酶联免疫检测检查 5 2例伤寒患者 ,2 0例正常人 ,进行对照观察。结果 细菌培养、肥达反应、伤寒杆菌H抗原的酶免疫检测对伤寒患者的诊断的阳性符合率分别为 34.6 % ,5 9.6 %和 86 %。结论 伤寒杆菌H抗原酶联免疫检测快速、特异、敏感为实验室检测的首选方法。

Objective: Objective To raise the positive coincident rate of typhoid. Methods: We examined and observed 52 patients with typhoid and 20 normal controls by bacterial culture, Widal reaction, and enzyme-linked immunoassay for detection of typhoid bacilli H antigen.Results: The positive coincident rate of bacterial culture, Widal reaction, and enzyme-lin ked immunoassay for detection of typhoid bacilli H antigen for diagnosing typhoid were 34.6%, 59.6%, 86%, respectively.Conclusions:Enzyme-linked immunoassay for detection of typhoid bacilli H antigen was the first selective method for laboratory examination of typhoid because of its fast, specificity and sensitivity.
