Abstract

Antibody evidence of porcine reproductive and respiratory syndrome virus detected in sera collected from feral swine (Sus scrofa) across the United States.

Abstract

Feral swine sera from across the United States were tested for antibodies to porcine reproductive and respiratory syndrome virus. Antibodies to the virus were detected in 1.2% (68 of 5506) of the samples tested, suggesting that feral swine are unlikely to be an important source of spillback into domestic swine.
