Scientists have produced pigs that may be protected from PRRS infection. The University of Edinburgh team have used advanced genetic techniques to produce pigs that are potentially resilient to the virus.

Gene-edited pigs show signs of resistance to major viral disease

Previous studies removed entire gene that enables PRRS virus to establish an infection, but new research shows only a portion of that gene needs to be removed.

Scientists have used advanced genetic techniques to produce pigs that are potentially resilient to porcine reproductive and respiratory syndrome (PRRS).

Previous studies have shown that the PRRS virus targets immune cells called macrophages. A molecule on the surface of these cells called CD163 plays a key role in enabling the PRRS virus to establish an infection.

In December 2015, team of researchers at the University of Missouri — supported by Genus PLC — produce
