Neospora Caninum Exposure In Overlapping Populations Of Coyotes (Canis Latrans) And Feral Swine (Sus Scrofa), Sarah N. Bevins, Emily Blizzard, Luis Bazan, Pat Whitley Jan 2013

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 …

Wildlife reservoir hosts of bovine tuberculosis (bTB) include Eurasian badgers (Meles meles) and brushtail possum (Trichosurus vulpecula) in the UK and New Zealand, respectively. Similar species warrant further investigation in the northern lower peninsula of Michigan, USA due to the continued presence of bTB on cattle farms. Most research in Michigan, USA has focused on interactions between white-tailed deer (Odocoileus virginianus) and cattle (Bos taurus) for the transmission of the infectious agent of bTB, Mycobacterium bovis, due to high deer densities and feeding practices. However, limited data are available on medium-sized …

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 Jan 2013

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 …
