Feral swine (Sus scrofa) are an ever-increasing problem across the United States. Besides physical environmental damage that they cause, they may harbor and transmit a number of pathogens to humans, livestock, and other domestic animals. We sampled feral swine across the state of Mississippi for titers to several diseases. Antibodies against Brucella were found in 16 of 499 (3.2%) feral swine, and antibodies against pseudorabies (porcine herpes virus, type 1; Herpesveridae sp.) virus were identified in 37 of 499 (7.4%) feral swine from across the state of Mississippi. Evidence of classical swine fever, African swine fever, swine influenza, and foot-and-mouth disease were not identified in any of the feral swine examined.
