An antigen capture enzyme-linked immunosorbent assay was developed by using monoclonal antibodies to conserved epitopes on the Anaplasma marginale MSP1a surface protein. The assay sensitivity was 1.1 (+/- 0.5)% parasitized erythrocytes, and all infected cattle were detected prior to development of 2.0%-parasitized erythrocytes. Positive tests preceded the onset of anemia by a mean of 2 days. The assay was specific for anaplasmosis, as demonstrated by nonreactivity with another common hemoparasitic pathogens.
利用针对边缘无形体MSP1a表面蛋白保守表位的单克隆抗体开发了一种抗原捕获酶联免疫吸附测定法。该测定法的灵敏度为1.1(±0.5)%的寄生红细胞,并且在寄生红细胞达到2.0%之前检测到了所有受感染的牛。阳性检测结果比贫血发作平均提前2天。该测定法对无形体病具有特异性,这通过与另一种常见血液寄生虫病原体无反应得到证明。
