Abstract: Distribution of Coronavirus Receptors in the Swine Respiratory and Intestinal Tract

Oct 21, 2022

Coronaviruses use a broad range of host receptors for binding and cell entry, essential steps in establishing viral infections. This pilot study evaluated the overall distribution of angiotensin-converting enzyme 2 (ACE2), aminopeptidase N (APN), carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1), and dipeptidyl peptidase 4 (DPP4) receptors in the pig respiratory and intestinal tract. All the receptors evaluated in this study were expressed and differentially distributed through the respiratory and intestinal tract. The presence and expression levels of these receptors could determine susceptibility to coronavirus infections. This study may have important implications for the development of research models and the assessment of the potential risk and introduction of novel coronaviruses into the swine population.

Video: Reducing Nursery Feed Costs Without Losing Performance - Dr. Julian Arroyave

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Julian Arroyave, a research swine nutritionist at Carthage Innovative Swine Solutions, discusses nursery feed budget strategies designed to reduce costs without compromising pig performance. He explains trials comparing high, medium, and low phase 1 and phase 2 feed budgets, including commercial validation data showing improved income over feed cost when lower-budget programs were applied under healthy herd conditions.
