IDENTIFICATION OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS
摘要
An enzyme-linked immunosorbent assay (ELISA) is based on the non-structural protein 7 (nsp7) of porcine reproductive and respiratory syndrome virus (PRRSV) and provides for the simultaneous detection and differentiation of serum antibodies directed against Type 1 (European) and Type 2 (North American) PRRSV. The invention provides a serological assay for the detection and/or differentiation of serum antibodies directed against Type 1 and/or Type 2 PRRSV utilizing PRRSV nsp7 as an antigen, and provides a diagnostic method for the detection of PRRSV infection, epidemiological surveys, and outbreak investigations. The invention may be used either alone or as a follow-up assay to determine the true status of unexpected positive results that may occur using other assays, such as the IDEXX HERDCHEK PRRS ELISA.
