LaboratoryPRRSV ORF5 gene sequence homology to Prevacent in Isolate by Sequencing
Definition
Percent genomic homology between a new isolated PRRS virus strain and a PPRS vaccine strain (e.g. Lelystad, Fostera, IngelvacMLV, IngelvacATP, PrimePac and Prevacent) is based on the number of matching amino acids per total amino acids sequenced in the open reading frame 5 (ORF5) gene. The more homologous the ORF5 gene sequences, the more closely the variants are related. It is thought that sequence homology between isolates and vaccines will predict vaccine efficacy, however this is currently debated since little is known about the immune response to PRRS virus.
