Abstract

A radioimmunoassay (RIA) has been developed to measure antibodies against Brucella abortus in bovine serum and can be used in the diagnosis of bovine brucellosis. The RIA measures the amount of specific antibody of the IgG1 and IgG2 subclasses but is insensitive to IgM, a characteristic which may make it more suitable than the complement fixation test (CFT) or the serum agglutination test for distinguishing infected animals from those which have been vaccinated with Br. abortus strain 19. The RIA is not subject to prozoning or ambiguous reactions, both of which interfere with the interpretation of the CFT.

摘要

已开发出一种放射免疫测定法(RIA)来检测牛血清中抗流产布鲁氏菌的抗体,可用于牛布鲁氏菌病的诊断。该放射免疫测定法可测量IgG1和IgG2亚类的特异性抗体量,但对IgM不敏感,这一特性可能使其比补体结合试验(CFT)或血清凝集试验更适合区分感染动物与接种过流产布鲁氏菌19号菌株的动物。放射免疫测定法不会出现前带现象或模糊反应,而这两种情况都会干扰补体结合试验的结果判读。
