Persistent pseudorabies exposure in US feral swine warrants vigilance for commercial herds; leaves open optimal wildlife control strategies.
Cross-Sectional (n=8,498)
Yes
Pseudorabies virus antibodies are widespread among feral swine in the US, posing a constant threat of reintroduction to the commercial swine industry.
Pedersen et al. (2013) conducted a cross-sectional in Pseudorabies virus infection (n=8,498). Pseudorabies virus exposure was evaluated on Pseudorabies virus antibody positivity. Among 8,498 serum samples from feral swine across the United States, 18% were positive for pseudorabies virus antibodies in 25 of 35 sampled states.
