Abstract

First reported in the United States in 1987 and in Europe in 1990, porcine reproductive and respiratory syndrome has rapidly become the most important infectious disease problem in the North American swine industry. The etiological agent, porcine reproductive and respiratory syndrome virus (PRRSV), is a member of the family Arterivirdae in the order Nidovirales. PRRSV is a single-stranded, enveloped, positive-sense RNA virus with a genome of approximately 15 kb in length containing 8 open reading frames (ORFs) which are expressed as subgenomic mRNA. At present, PRRSV is present in at least 60 percent of North American swine herds (USDA:APHIS:VS, 1997)
