| serologic survey for transmissible gastroenteritis virus neutralizing antibodies in selected feral and domestic swine sera in the southern united states. | serum samples collected from feral and domestic swine (sus scrofa) in florida and feral swine in georgia and texas were assayed by plaque reduction for their virus neutralizing (vn) antibodies against the porcine transmissible gastroenteritis virus (tge). none of 560 samples collected from feral swine contained vn antibodies for tge virus, but experimentally infected feral swine seroconverted. none of 665 samples from domestic swine contained tge-vn antibodies. these results indicate feral swine ... | 1990 | 2167395 |
| quantitative approach for the risk assessment of african swine fever and classical swine fever introduction into the united states through legal imports of pigs and swine products. | the us livestock safety strongly depends on its capacity to prevent the introduction of transboundary animal diseases (tads). therefore, accurate and updated information on the location and origin of those potential tads risks is essential, so preventive measures as market restrictions can be put on place. the objective of the present study was to evaluate the current risk of african swine fever (asf) and classical swine fever (csf) introduction into the us through the legal importations of live ... | 2017 | 28797058 |
| influenza exposure in united states feral swine populations. | swine play an important role in the disease ecology of influenza. having cellular receptors in common with birds and humans, swine provide opportunities for mixed infections and potential for genetic reassortment between avian, human, and porcine influenza. feral swine populations are rapidly expanding in both numbers and range and are increasingly coming into contact with waterfowl, humans, and agricultural operations. in this study, over 875 feral swine were sampled from six states across the ... | 2008 | 18436668 |
| prevalence of pseudorabies (aujeszky's disease) virus antibodies in feral swine in florida. | 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. ... | 1993 | 8394943 |
