Patent Title: RESTRICTION ENZYME SCREEN FOR DIFFERENTIATING PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROM VIRUS STRAINS
|
Patent Number: 6015663
Docket Number: 10796
Serial Number: 8609334
Date Patented: 01/18/2000
Agency:
Agricultural Research Service
Date Filed:
March 1, 1996
Abstract:
The invention is a way to distinguish RespPRRSr vaccine from wild strains of porcine
reproductive and respiratory syndrome virus (PRRSV) and to distinguish the virulent field strains
of PRRSV from one another. The invention uses a segment of the viral genome which differs
sufficiently among various strains for a sensitive, reliable and rapid assay of PRRSV suitable for
large-scale heard screening.
