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: Welfare That Works on Farm - Dr. Anna Wallenbeck

In this episode of The Swine it Podcast Show Canada, Dr. Anna Wallenbeck from the Swedish University of Agricultural Sciences discusses how producers can evaluate and improve pig welfare in practice. She discusses group housing, social behavior, transport, slaughter practices, welfare regulations, and production economics. Dr. Wallenbeck also examines how management decisions influence pig welfare and farm competitiveness. Listen now on all major platforms!

“Animal welfare legislation is one animal protection measure, but we still have to look at the animals to understand their actual welfare.”

Meet the guest: Dr. Anna Wallenbeck is an Associate Professor in Animal Production Systems, Senior Lecturer in Animal Welfare, and Deputy Dean of the Faculty of Veterinary Medicine and Animal Science at the Swedish University of Agricultural Sciences. Her work connects animal welfare, production systems, and practical solutions for livestock farming.
