A review of PRRSV nomenclature and current circulating PRRSV strains in the U.S.

What’s in a name? For PRRSV, there are multiple classification systems used to describe PRRSV strains (i.e. RFLP’s, genotype, and lineage) and we will review the history and evolution of these systems and how we use them today. Our goal is that when discussing PRRSV with your peers we are all talking the same “language”.
