Dr. Matheus Costa, Associate Professor at the Western College of Veterinary Medicine, and his research team have identified a powerful naturally occurring molecule that could change the game. This molecule not only kills bacteria—it also strengthens a pig’s immune response, helping it fight off multiple pathogens, including viruses and potentially even fungi.
The discovery emerged during trials focused on swine dysentery, a costly and persistent disease in global pig production.
All pigs in the study shared the same genetics, environment, and feed—but some remained resilient. Upon deeper investigation, the researchers found that these pigs carried higher levels of a specific peptide or protein—a naturally occurring molecule that appeared to be doing double duty: fighting off harmful bacteria and modulating the immune response.
