title: Study of the delivery of the gD gene of pseudorabies virus to one-day-old piglets by adenovirus or plasmid DNA as ways to by-pass the inhibition of immune response by colostral antibodies.
abstract: In the present study, it was shown that piglets with maternal antibodies, which had been primed with a replication-defective adenovirus that expresses the pseudorabies virus (PRV) glycoprotein gD and boosted with the Bartha vaccine strain at 10 weeks of age are equally protected clinically upon a challenge as piglets without maternal antibodies vaccinated with the same approach or with the Bartha vaccine strain alone. Priming with a plasmid that expresses gD was less efficient.
