NRI PROGRAM PROJECT ON "INTEGRATED CONTROL AND ELIMINATION OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS (PRRSV) IN THE U.S."

Assess gene expression patterns of immune markers in pigs infected or vaccinated with porcine reproductive and respiratory syndrome virus (PPRSV) for various NC229 (Swine PRRSV project) collaborators. 1) With UNE test 60 RNA and cDNA preparations from lung tissue collected from pigs infected with PRRSV and determine whether specific immune markers are associated with differences in resistant versus susceptible pig anti-PRRSv responses. 2) With SD State immune responses from boars infected with PRRSV will be compared. With UIL gene expression patterns of RNA prepared from blood cells from pigs vaccinated for PRRSV will be assessed and effect of in vitro culture time compared.
