摘要: 在无“金标准”的情况下,为评估虎红平板凝集试验(RBT)、荧光偏振分析法(FPA)和间接酶联免疫吸附试验(IELISA)用于奶牛布鲁氏菌病的抗体检测能力,作者分别以RBT、FPA、IELISA 3种方法对采自某奶牛场的血清样品进行检测,通过贝叶斯分析法对检测结果进行分析,研究3种方法检测奶牛布鲁氏菌血清抗体的敏感性(Se)和特异性(Sp)。结果显示,RBT、FPA、IELISA 3种检测方法的敏感性(Se)分别为91.81%、95.92%和95.98%;特异性(Sp)分别为98.80%、86.54%和98.65%。本研究表明,3种血清学检测方法中以IELISA的检测能力最好。

Abstract: The objective of our study was to evaluate the diagnostic performance of three serological tests for brucellosis. Serological test results were used to compare the performance of Rose Bengal Test (RBT), indirect ELISA (IELISA) and Fluorescence Polarisation Assay (FPA) in diagnosing brucellosis in cattle. Their performance was evaluated using Bayesian analysis which allows the sensitivity (Se) and specificity (Sp) to be estimated in the absence of a gold standard. The sensitivity of RBT, FPA and IELISA were 91.81%, 95.92% and 95.98%, respectively; and specificity of RBT, FPA and IELISA were 98.80%, 86.54% and 98.65%, respectively. The results demonstrated that the IELISA performing well in diagnosing brucellosis in cattle.
