Ixodid Ticks Associated With Feral Swine In Texas, David M. Sanders, Anthony L. Schuster, P Wesley Mccardle, Otto F. Strey, Terry L. Blankenship, Pete D. Teel

Ixodid ticks were collected from feral swine in eight Texas ecoregions from 2008-2011. Sixty-two percent of 806 feral swine were infested with one or more of the following species: Amblyomma americanum, A. cajennense, A. maculatum, Dermacentor albipictus, D. halli, D. variabilis, and Ixodes scapularis. Juvenile and adult feral swine of both sexes were found to serve as host to ixodid ticks. Longitudinal surveys of feral swine at four geographic locations show persistent year-round tick infestations of all gender-age classes for tick species common to their respective geographic locations and ecoregions. Amblyomma americanum, A. cajennense, A. maculatum and D. variabilis were …
Neospora Caninum Exposure In Overlapping Populations Of Coyotes (Canis Latrans) And Feral Swine (Sus Scrofa), Sarah N. Bevins, Emily Blizzard, Luis Bazan, Pat Whitley

Limited information exists on Neospora caninum transmission dynamics in wildlife. This coccidian parasite, whose presence can lead to substantial economic losses in cattle operations, requires a canid definitive host for reproduction. We examined exposure in a definitive host, coyotes (Canis latrans), and in overlapping populations of feral swine (Sus scrofa) to determine if spatial proximity between a definitive and incidental host influences the likelihood of parasite exposure. Eighteen percent of coyotes (95% confidence interval [CI]514.2–21.8) and 15.8% of feral swine (95% CI512.5–19.2) had been exposed to N. caninum, and this is the first report of exposure …

There are no registered toxins available for use on Feral Swine (Sus scrofa, Linnaeus) in the United States. HOGGONE is a proprietary bait matrix under development in Australia that delivers toxic levels of sodium nitrite to feral swine. However, one challenge is to develop a species-specific oral delivery system to deliver toxins to feral swine in the USA while minimizing non-target wildlife exposure. The HOGHOPPERTM is a lightweight and portable bait delivery system that could overcome this problem. Our objective was to compare non-toxic HOGGONE removal by wildlife that visited HOGHOPPERS during acclimation periods (doors open; free-feeding …
Pseudorabies In Feral Swine In The United States, 2009–2012, Kerri Pedersen, Sarah N. Bevins, John A. Baroch, James C. Cumbee Jr., Shannon C. Chandler, Billy S. Woodruff, Troy T. Bigelow, Thomas J. Deliberto

Although pseudorabies virus can affect a wide range of mammalian and avian hosts, swine are the only natural hosts of the virus. The US commercial swine industry obtained pseudorabies-free status in 2004, which was important because of the economic value of domestic swine production; however, feral swine remain competent hosts and represent a constant threat for reintroducing the virus into the commercial industry. To better assess feral swine infection status, we collected 8,498 serum samples from feral swine across the United States between 1 October 2009 and 30 September 2012. Of these, 18% were antibody positive in 25 of 35 …
