Porcine reproductive and respiratory syndrome virus (PRRSV) is a common cause of abortion and reproductive failure in swine. The mechanism of abortion is not fully defined, and the effect of the virus on luteal function has not been explored. Late-term pregnant swine were exposed to varied doses of PRRSV strain NADC-8. Effects on ovarian function were evaluated by serial determination of plasma progesterone levels and by microscopic evaluation of ovarian pathologic alterations combined with immunohistochemistry and in situ hybridization to detect PRRSV antigen. No specific trend in plasma progesterone level associated with PRRSV infection status was identified. Microscopic ovarian lesions were not identified and PRRSV antigen was not demonstrated in ovarian tissues by immunohistochemistry or in situ hybridization at necropsy 21 days postexposure. Based on these findings it does not appear that either a direct or an indirect effect on luteal function contributes to PRRSV-induced abortion. INTRODUCTION Porcine reproductive and respiratory syndrome (PRRS) was first described in 1987 in 10. 20, 23 the United States and since has spread worldwide. " The syndrome is caused by an 22 encapsulated, single-stranded, positive-sense RNA virus designated PRRSV. Porcine reproductive and respiratory syndrome virus is classed in the order Nodovirales, family Arteriviridae, genus Arterivirus along with equine arteritis virus (EAV), lactate
