12:47pm Bioinformatics for PRRSV Sequences: Tools & Applications

Rabsa Naseer, Graduate Student, Iowa State University, Ames, IA

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.

12:59pm PRRSV in U.S. Swine Herds: Updated Economic Costs Attributable to Lost Productivity

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. 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.
