Inhibitors of cell enzyme Inosine 5 ́-Monophosphate (IMP) dehydrogenase – Ribavirine (Rbv), Micophenolic acid (MPA) and Mizoribine (MZR) have potential application as antiherpes agents in combination with acyclovir (ACV). The effectivity of action of ACV on herpesvirus replication is improved after decreasing of the concentration of dGTP as a result of IMP dehydrogenase inhibition. The antiviral...

A collection of overlapping cDNA clones encoding the latency transcript of pseudorabies virus and the DNA nucleotide sequence of the latency gene has been obtained. The transcript is spliced with 4.6 kb of intervening sequences. This mRNA, designated the large latency transcript, is 8.5 kb. It is polyadenylated and contains a large open reading frame capable of coding for a 200-kDa polypeptide....

Two specific and sensitive, indirect enzyme-linked immunosorbent assays (ELISAs) utilizing a protein G-peroxidase conjugate were developed to detect antibodies to the pseudorabies virus (PRV) and the transmissible gastroenteritis virus (TGEV) in pig sera. Sera from 5,337 pigs, obtained from various abattoirs in South Africa, were tested with both ELISAs. No serological evidence of infection wit...
