ABSTRACT:
Pigs challenged with hypoglycosylated variants of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) major surface protein GP5 exhibited increased production of PRRSV-neutralizing antibodies relative to the levels of neutralizing antibodies produced by pigs immunized with wild type (wt) or glycosylated GP5. This invention provides for methods of obtaining improved immune responses in pigs to PRRSV, compositions useful for obtaining the improved immune responses as well as isolated polynucleotides that encode hypoglycosylated variants of PRRSV major surface protein GP5.
