Molecular analysis of pseudorabies viral vaccines and their rapid differentiation from wild-type isolates using DNA-amplified glycoprotein I and thymidine kinase gene segment polymorphisms.


Several conventional and genetically recombinant modified-live viral (MLV) vaccines are used to control pseudorabies virus infections (Aujeszky's disease, PRV) in swine. Differentiating vaccinal PRV (V-PRV) from wild PRV (WT-PRV) is important for herd health, regulatory and forensic purposes, and for studies of PRV latency and epidemiology. All PRV vaccines… (More)
