Scientists develop PRRS-resistant pigs
Scientists have long tried to understand how PRRS infects pigs.

Exclusive deal signed with global leader in animal genetics

Pigs that are resistant to Porcine Reproductive and Respiratory Syndrome (PRRS) have been developed by researchers in the United States.

Scientists have long tried to understand how PRRS infects pigs. Until recently, researchers believed the virus entered pigs by being inhaled into the lungs, where it attached to a protein called sialoadhesin.

But two years ago, a team from the University of Missouri found that the elimination of sialoadhesin had no effect on a pig’s likelihood of developing PRRS. A second protein, known as CD163, was thought to “uncoat” the virus and allow it to infect pigs.

In this latest study, published in Nature Biotechnology, researchers set out to see if they could prevent pigs from producing CD163.

The team genetically engineered the gene that makes CD163 so the pigs could no longer produce it. Next, they infected the pigs and found that those without CD163 never got sick, nor did they show any other changes in their development. 

Study co-author Kristin Whitworth said that the discovery “could have enormous implications for pig producers and the food industry throughout the world.”

In light of their results, the University of Missouri has signed an exclusive global licensing deal for the potential future commercialisation of the virus-resistant pigs with Genus, plc - a global leader in animal genetics.

The University said in a press release that, if the development stage is a success, the commercial partner will seek the necessary approvals and registration from governments before a wider market release.

FIVP launches CMA remedies survey

News Story 1
 FIVP has shared a survey, inviting those working in independent practice to share their views on the CMA's proposed remedies.

The Impact Assessment will help inform the group's response to the CMA, as it prepares to submit further evidence to the Inquiry Group. FIVP will also be attending a hearing in November.

Data will be anonymised and used solely for FIVP's response to the CMA. The survey will close on Friday, 31 October 2025.

Free webinar explores congenital heart disease in dogs

A free webinar is to provide veterinary professionals, dog breeders and pet owners an new insights into congenital heart disease.

Chris Linney, a cardiology specialist and Veterinary Cardiovascular Society (VSC) member, will present the webinar from 7.00pm to 8.30pm on Wednesday, 12 November.

Dr Linney will explore the types, causes and clinical presentation of congenital heart conditions. This will include diagnostic approaches, treatment pathways and emerging research opportunities.

The session is the third to be organised by The Kennel Club, with the VCS, following an introductory webinar and a talk on acquired heart disease. Dr Linney's webinar consists of a one-hour presentation, followed by a 30-minute question and answer session.

Dr Linney said: "This webinar will be an opportunity to deepen understanding - not just of the diseases themselves, but of how breeders, vets and owners can work together to support affected dogs and improve outcomes for future generations."
