Feather groups prepped for spring bird flu

With migratory birds set to return soon, Manitoba poultry groups are bracing for an increased threat of bird flu.

“We’re hoping for the best but we’re preparing for another challenge like we had in the fall,” said Cory Rybuck, general manager of Manitoba Egg Farmers.

Migratory birds are considered the most common source of Highly Pathogenic Avian Influenza (HPAI) infections on farms. Clothing and equipment can become contaminated by droppings, which can then spread the disease.

“Scientific evidence indicates that HPAI circulates naturally in wild birds, and is spread through migratory birds,” a Canadian Food Inspection Agency spokesperson told the Co-operator. “Spring migration for birds has already begun and is expected to last until June.”

Video: New discovery may lead to better vaccines for pork producers



Porcine reproductive and respiratory syndrome virus (PRRSV) causes severe disease in pigs, leading to significant economic losses for pork producers across the globe. It’s estimated that PRRS costs the Canadian pork industry $130M annually. Using the CMCF beamline, researchers from the University of Manitoba and the Leiden University Medical Centre (Netherlands) were able to see the structure of the PRRSV protease, a type of protein the pathogen uses to suppress a host’s immune system. The vital information they uncovered can be used to develop new vaccines against PRRSV and also helps inform development of vaccines against emerging human viruses.
