Key result
Florida feral swine show ~35% seroprevalence for pseudorabies virus antibodies.
Why the study?
The prevalence and distribution of pseudorabies virus antibodies in feral swine populations in Florida were not well characterized.
Cross-Sectional (n=1,662)
Yes
Pseudorabies virus infections are widespread in Florida feral swine, which may undermine eradication efforts in domestic swine populations.

Alerts to PRV reservoirs in feral swine; leaves open current prevalence and transmission risks.
Serum samples collected from feral swine (Sus scrofa) throughout Florida (USA) from 1980 to 1989 were tested for antibodies to pseudorabies virus (PRV) by the serum neutralization test, the latex agglutination test, or by the enzyme-linked immunosorbent assay. Seropositive swine were detected at 11 of 13 sites with a composite seroprevalence of 34.8% (579 of 1,662 samples; range = 5.9% to 58.2%) for sites with seropositive swine. Data on age and sex of the swine were available from three sites. Seroprevalence in males and females did not differ significantly (P = 0.62 for the combined data). Seroprevalence in adult (> or = 8 mo) and juvenile swine (< 8 mo) was significantly different at all sites (P < 0.05 for the combined data). From these data, PRV infections appear to occur widely in populations of Florida feral swine and may seriously undermine efforts to eradicate this virus from the domestic swine population of the USA.

Leek et al. (1993) conducted a cross-sectional in Pseudorabies virus (PRV) infection (n=1,662). Pseudorabies virus (PRV) infection was evaluated on Seroprevalence of pseudorabies virus antibodies. Pseudorabies virus antibodies were detected in feral swine at 11 of 13 Florida sites with a composite seroprevalence of 34.8% (579 of 1,662 samples).
