Agenda
Dr. Chris Rademacher, Clinical Professor, Iowa State University, Ames, IA
Dr. Giovani Trevisan Research Assistant Professor, Iowa State University, Ames, IA
Information about how to use next generation sequencing for PRRSV management and occurrence of recombination, implications, and how to avoid will be presented. Both subjects are part of two factsheets recently developed by the PRRSV Task Force Committee and approved by the AASV Board.

Porcine reproductive and respiratory syndrome is the most economically important swine disease in North America. The Swine Disease Reporting System and the Iowa State Veterinary Diagnostic Laboratory have developed a suite of bioinformatics tools to meet the challenge of this disease. This presentation will guide you through a suite of tools that allow clients to have an overview of PRRS prevalence, which lineages are prominent, and provides comparison and classification for client sequences.
Dr. Henry Osemeke, Postdoctoral Associate, Iowa State University, Ames, IA
The most recent estimate of the economic impact of lost productivity in U.S. swine herds due to PRRSV was published in 2013, based on data from 2005 to 2010. Over the past decade, the U.S. swine industry has made significant advancements in prevention, control, and elimination strategies for PRRSV, Mhp, and other important swine pathogens. Additionally, we’ve seen the emergence and reemergence of PRRSV variants, as well as fluctuations in prices and costs.Given all these changes, has the economic impact of PRRSV shifted?
Dr. Chris Rademacher, Clinical Professor, Iowa State University, Ames, IA
Review of the POMP program, including what it takes to enroll and what we are learning in terms of production practices that will limit the impact from PRRS outbreaks in breeding herds.
Dr. Ana Paula Silva, Postdoc Research Associate, Iowa State University, Ames, IA
POMP is an epidemiologic tool that gathers information on health interventions to control outbreaks and tracks PRRSV outbreak recovery production outcomes. As various swine companies are enrolled, POMP can be used for benchmarking to understand how and where the swine producers need to change to improve performance.
Dr. Reid Phillips, A.D. Technical Manager, Boehringer Ingelheim Animal Health, Parkville, MO
The presentation will review and summarize the history of the BI-GRANTS research program. Will highlight selected research projects that have generated field applicable research knowledge and provide an update of recent research awards and projects.
Dr. Isadora Machado, Graduate Student, Iowa State University, Ames, IA
In recent years, population-based options for PRRSV monitoring have emerged, such as oral fluids (OF), family oral fluids (FOF), processing fluids (PF), and tongue fluids (TF). A common question from producers is, “When should I opt for each sample type?” This study summarizes previous research and guides veterinarians and pig producers to strategize PRRSV monitoring in breeding herds undergoing PRRSV elimination.
Dr. Mafalda Mil-Homens, Graduate Student, Iowa State University, Ames, IA
The presentation will emphasize the importance of leveraging industry data, such as key production indicators collected on swine farms, to enhance disease surveillance systems.

Our viability PCR assay was recently published in the Virology Journal (Balestreri et al 2024), which clearly demonstrates our ability to accurately measure the stability of three viruses (EhV, ASFV & PRRSV) under different temperature exposures. We also applied this assay to calibrate current mitigation or inactivation methods that previously relied solely on cell culture-based methods data to confirm virus inactivation. Confirming the viable state for viruses could have unprecedented implications for businesses directly or indirectly connected to the swine industry.

In the last 5 years, the US swine industry has seen an increase in post-weaning diarrhea cases caused by F18 Escherichia coli. A natural genetic resistance associated with different genotypes of the gene FUT1 has been described. With the increase in cases of F18 E. coli, questions regarding susceptibility in pigs of specific genetic lines have risen. This talk will address the questions of genetic resistance and susceptibility to F18 E. coli in different genetic lines and the outcomes of the challenge with a contemporary highly virulent isolate.
