Q&A: Pork, pathogens and progress—a close look at PRRSV research

The pork industry provides people across different cultures a considerable source of protein, essential nutrients and a versatile ingredient for diverse culinary traditions. So, when the problem of porcine reproductive and respiratory syndrome virus (PRRSV) infection in the pork industry results in an economic loss of $650 million annually in the United States, finding a solution is of critical significance.

A diverse group of researchers at the Faculty of Science and Leiden University Medical Center, The Netherlands, recently published a paper sharing their discovery on better understanding and managing PRRSV. The following interview is with Dr. Brian Mark, professor at the department of microbiology and dean of the Faculty of Science, who leads a laboratory focused on understanding the molecular basis of diseases.

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
