Porcine coronaviruses have been present in the U.S. swine industry for several years (Stevenson et al., 2013). Transmissible gastroenteritis virus (TGEV), porcine epidemic diarrhea virus (PEDV) and porcine Deltacoronavirus (PDCoV) continue to be part of the list of differential diagnosis when facing a clinical case of gastrointestinal disease (Marthaler et al., 2014; Turlewicz-Podbielska & Pomorska-Mól, 2021; Xia et al., 2018; Zimmerman., 2019). Unfortunately, both PEDV and PDCoV are responsible for breaks in breeding herds indicating that the virus continues to transmit within the pig population.
Even though the incidence of both viruses in the breeding herd population remains below 10% (MSHMP, 2021), it is not well understood what the situation is in the growing pig herd. Pig production companies continue to invest resources in order t

In recognition of the value and need for research with direct application to the swine veterinary profession, the American Association of Swine Veterinarians (AASV) Foundation has granted $25,111 to Guilherme Milanez Preis, PhD student in the University of Minnesota’s Veterinary Medicine Graduate Program, and Cesar Corzo, DVM, MS, PhD, associate professor in the University of Minnesota’s Department of Veterinary Population Medicine, to assess senecavirus A (SVA) shedding and transmission in growing pig populations.
SVA has circulated amongst the United States swine herd for more than 30 years, generating losses and anxiety among producers due to its resemblance to foot-and-mouth disease. The new study aims to describe SVA shedding patterns over time in growing pig populations and assess the state of infection in piglets after co-mingling in the nursery.

In recognition of the value and need for research with direct application to the swine veterinary profession, the AASV Foundation increased the amount of funding available for research proposals in 2021 from $60,000 to $100,000. Dr Lisa Tokach, chair of the AASV Foundation, announced the selection of four research proposals for partial funding during the foundation’s annual meeting, which was held virtually during the AASV annual meeting. The foundation granted funds to support efforts by researchers at the University of Minnesota, Iowa State University, and South Dakota State University.
The Foundation granted $25,111 to Dr. Guilherme Milanez Preis and co-investigator Dr. Cesar Corzo from the University of Minnesota to fund the proposal, “Assessing senecavirus A shedding and transmission in growing pig populations.” The two objectives of the study are to describe SVA shedding patterns over time in growing pig populations and assess the state of infection in pigl

Researchers from North Carolina State University used a three-model approach to trace the between-farm spread of porcine epidemic diarrhea virus (PEDV), as well as to analyze the efficacy of different control strategies in these scenarios. The approach may enable farmers to be more proactive in preventing the spread of PEDV and to optimize their efforts to control the disease.
PEDV is a virus that causes high mortality rates in preweaned piglets. The virus emerged in the U.S. in 2013 and by 2014 had infected approximately 50 percent of breeding herds. PEDV is transmitted by contact with contaminated fecal matter. We wanted to compare three different models by using actual outbreak data in order to test their efficacy, says Gustavo Machado, assistant professor of population health and pathobiology at NC State and corresponding author of a paper describing the work. Then we could use the data to determine the best intervention strategy in each case.
