U.K.-based Genus teams with U.S. scientists for resilient pigs

Porcine reproductive and respiratory syndrome is a deadly virus that causes an estimated $550 million in damage to swine producers each year. Now U.K.-based Genus says it has used gene editing to create pigs that are resistant to the virus, and that it will continue to develop the technology under an exclusive license with the University of Missouri.

Deadly pig virus likely carried into U.S. from China

The USDA believes it has found the source of the porcine epidemic diarrhea virus (PEDv) that spread rapidly through farms in the U.S. in 2013, ultimately killing 8 million piglets and sapping the nation's hog supply by 10%. The virus was nearly identical in DNA to a similar illness in China and was likely carried into the United States via tote bags used in international trade, the agency said Wednesday.
