24 - Dr. Helm: The effect of Ileitis on the immune function of the pig's gut

Lawsonia intracellularis can have a significant impact on the capabilities of the small intestine of pigs. This can cause a wide range of effects, from weakened immunological function to reduced nutrient absorption and slowed growth. In this episode, Dr. Emma Helm explains her research study, which had the intention of explaining some of the physiological changes in the small intestine of swine that can occur due to a Lawsonia outbreak.

Meet the guest:

Dr. Helm received her M.S.  and her Ph.D.  in Animal Sciences from Iowa State University. Her research focused on how swine intestinal integrity, intestinal function, and skeletal muscle metabolism are affected by various health challenges caused by pathogens, such as Lawsonia intracellularis and Brachyspira hyodysenteriae. After finishing her post-doctorate, she accepted a position at Virginia Tech, where she has been acting as a Research Assistant Professor. Dr. Helm plans to focus current and future research efforts on understanding the biological mechanisms that define swine physiology, particularly intestinal physiology, during stress events.
