September Domestic Swine Disease Monitoring Report Now Available

Sep 04, 2025

The Swine Health Information Center’s (SHIC) September Domestic Swine Disease Monitoring Report is available.

This month’s Domestic Swine Disease Monitoring Report adds information on a new pathogen: Escherichia coli genotype PCR. A bonus page and podcast explain the E. coli data. PRRSV overall case positivity decreased, remaining below 20% as expected for the summer period. However, PRRSV case positivity is still above the expected levels in Iowa and Minnesota. PEDV case positivity also remains low, but in the wean-to-market category, there was a moderate increase in positive cases, raising concern for biosecurity in finishing sites. Influenza A case positivity achieved the lowest percentage (18%) since 2010, highlighting that IAV detection is below the expected levels compared with historical data. Finally, in the confirmed tissue diagnosis from Iowa State University, there was a moderate increase in the number of Sapovirus cases detected.

In the podcast, Dr. Marcelo Almeida, assistant clinical professor and diagnostician at ISU, discusses the recent E. coli PCR genotype trends, the main E. coli virotypes and pathotypes, and tips for E. coli control on farms.

Video: Sweetener Effects on Gut Health - Dr. Kwangwook Kim

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Kwangwook Kim, Assistant Professor at Michigan State University, discusses the use of non-nutritive sweeteners in nursery pig diets. He explains how sucralose and neotame influence feed intake, gut health, metabolism, and the frequency of diarrhea compared to antibiotics. The conversation highlights mechanisms beyond palatability, including hormone signaling and nutrient transport. Listen now on all major platforms!

“Receptors responsible for sweet taste are present not only in the mouth but also along the intestinal tract.”

Meet the guest: Dr. Kwangwook Kim / kwangwook-kim is an Assistant Professor at Michigan State University, specializing in swine nutrition and feed additives under disease challenge models. He earned his M.S. and Ph.D. in Animal Sciences from the University of California, Davis, where he focused on intestinal health and metabolic responses in pigs. His research evaluates alternatives to antibiotics, targeting gut health and performance in nursery pigs.
