MANHATTAN —New research from the Kansas State 1xbet online casino College of Veterinary Medicine provides the first investigation into how feed and feed ingredients may be playing a role in the spread of two 1xbet online casino viruses of global significance.
Megan Niederwerder, lead researcher and K-State assistant professor of diagnostic medicine and pathobiology, and her colleagues have published the first report of classical swine fever 1xbet online casino and pseudorabies 1xbet online casino stability in feed ingredients subjected to different environmental conditions mimicking transpacific shipment. "Stability of classical swine fever 1xbet online casino and pseudorabies 1xbet online casino in animal feed ingredients exposed to transpacific shipping conditions" is available online in the journal Transboundary and Emerging Diseases.
"Classical swine fever 1xbet online casino and pseudorabies 1xbet online casino cause two of the top four transboundary animal diseases of importance to swine," Niederwerder said. "Both viruses are endemic to areas of the world where feed ingredients are manufactured and imported into the United States each year."
Currently, U.S. commercial swine are free of both classical swine fever 1xbet online casino and pseudorabies 1xbet online casino because of costly eradication programs completed in 1978 and 2004, respectively. Niederwerder said reintroduction of these viruses into U.S. swine herds would be devastating and that there are concerns that feed ingredients incorporated into swine diets may serve as new sources for the spread of animal diseases with economic and welfare significance. Recent changes in pseudorabies 1xbet online casino strain virulence and classical swine fever 1xbet online casino geographic distribution are of great concern for these trade-limiting diseases.
"The emerging threat of classical swine fever 1xbet online casino and pseudorabies 1xbet online casino being reintroduced into U.S. commercial swine is significant and preventing entry is critical for the U.S. pork industry," Niederwerder said. "The route of introducing and transmitting swine viruses through feed has been recognized since the 2013-2014 outbreak of porcine epidemic diarrhea 1xbet online casino . However, the stability of classical swine fever 1xbet online casino and pseudorabies 1xbet online casino in imported feed ingredients had yet to be investigated."
In the researchers' study, they found both viruses survived for the length of the 37-day model in feed, with pseudorabies 1xbet online casino having increased stability across a broader range of feed ingredients when compared to classical swine fever 1xbet online casino .
Niederwerder said pseudorabies 1xbet online casino was detected in nine of the 12 tested ingredients: conventional and organic soybean meal, lysine, choline, vitamin D, moist cat and dog food, dry dog food, and pork sausage casings at the conclusion of the simulated voyage. When looking at classical swine fever 1xbet online casino , two of the 12 ingredients had infectious 1xbet online casino detected: conventional soybean meal and pork sausage casings.
"This study reports novel data about environmental stability of classical swine fever 1xbet online casino and pseudorabies 1xbet online casino in feed and includes important quantitative information that can be incorporated into risk models for preventing the potential spread of classical swine fever 1xbet online casino and pseudorabies 1xbet online casino through imported feed ingredients," Niederwerder said. "This information adds to our work on African swine fever and reinforces the concept of feed biosecurity for disease prevention."
This research was conducted at Kansas State 1xbet online casino 's Biosecurity Research Institute, a biosafety level-3 and biosafety level 3Ag facility that allows safe and secure research with animal and plant diseases foreign to the U.S., in collaboration with other 1xbet online casino and industry contributors. Co-authors on the manuscript include Ana Stoian, Vlad Petrovan, Laura Constance, Matthew Olcha, Maureen Sheahan and Bob Rowland with Kansas State 1xbet online casino ; Scott Dee, Pipestone Veterinary Services; Diego Diel, Cornell 1xbet online casino ; and Gil Patterson, Lincoln Memorial 1xbet online casino .
Funding for this study was provided by the 1xbet online casino Health Information Center and the State of Kansas National Bio and Agro-defense Facility Fund.
