The AASV PRRS Task Force is asking for your feedback regarding PRRS nomenclature.
Given modern advances in sequencing technology and widespread use of ORF5 sequences, it is becoming increasingly apparent than using RFLP-types to refer to PRRSV (type 2) viruses is both out-dated and, more importantly, can often lead to misleading or even erroneous conclusions. While the shortcomings of RFLP-types have long been recognized, no alternatives have yet been proposed. Lineages and sub-lineages attempt to provide more biologically meaningful classification for PRRS viruses, but do not have the level of granularity often required for on-farm management of PRRSV.
Results of this 5 question survey aim to assess how PRRSV sequence data and related nomenclature are being used in the industry, and identify attributes of an ideal naming system that would meet the needs of swine practitioners to track PRRS at the farm, system, regional, and national scales. This survey will serve as key information for initiatives to update PRRS nomenclature.
