A blocking enzyme-linked immunosorbent assay (ELISA) for detecting antibodies to the porcine reproductive and respiratory syndrome virus (PRRSV) in pig sera was developed and compared with the immunoperoxidase monolayer assay (IPMA), the most widely used serological diagnostic test in Europe. The blocking ELISA was specific and more sensitive than the IPMA when applied to field sera and to sera which were collected early after an experimental infection with PRRSV. Problems with high background activity as observed in IPMA or indirect ELISA were not encountered.
开发了一种用于检测猪血清中猪繁殖与呼吸综合征病毒(PRRSV)抗体的阻断酶联免疫吸附测定(ELISA),并将其与免疫过氧化物酶单层测定(IPMA)进行比较,IPMA是欧洲使用最广泛的血清学诊断试验。当应用于现场血清和PRRSV实验感染后早期采集的血清时,阻断ELISA具有特异性且比IPMA更敏感。未遇到在IPMA或间接ELISA中观察到的高背景活性问题。
