Genes homologous to the herpes simplex virus UL49.5 open reading frame are conserved throughout the Herpesviridae. In the alphaherpesvirus pseudorabies virus (PrV), the UL49.5 product is an O-glycosylated structural protein of the viral envelope, glycoprotein N (gN) (A. Jöns, H. Granzow, R. Kuchling, and T. C. Mettenleiter, J. Virol. 70:1237-1241, 1996).(More)
Basolateral uptake of chloride by the HCl-secreting parietal cells of the gastric (oxyntic) glands is most likely mediated by a HCO− 3/Cl− anion exchange mechanism. Circumstantial evidence indicates that in rodents the anion exchange proceeds through an anion exchanger 2(AE2)-like membrane protein. In the present study, we raised antibodies against a(More)
We reinvestigated major steps in the replicative cycle of pseudorabies virus (PrV) by electron microscopy of infected cultured cells. Virions attached to the cell surface were found in two distinct stages, with a distance of 12 to 14 nm or 6 to 8 nm between virion envelope and cell surface, respectively. After fusion of virion envelope and cell membrane,(More)
Sequence analysis of BamHI fragment 1 of the pseudorabies virus (PrV) genome identified a novel PrV gene located upstream of the UL50 gene encoding PrV dUTPase. The deduced protein product displayed homology to the product of the herpes simplex virus type 1 UL49.5 protein. The predicted PrV UL49.5 protein consists of 98 amino acids with a calculated(More)
Vaccination with DNA constructs encoding viral antigens has been shown to induce antiviral immunity in various model hosts. However, relevant natural virus-host systems have so far been analysed to only a very limited extent. To test the efficacy of DNA vaccination in an economically important large animal, pigs were immunized against Aujeszky's disease, a(More)
Glycoproteins gM and gN are conserved throughout the herpesviruses but are dispensable for viral replication in cell cultures. To assay for a function of these proteins in infection of an animal, deletion mutants of pseudorabies virus lacking gM or gN and corresponding revertants were analyzed for the ability to penetrate and propagate in the nervous(More)

Sequence analysis within the long segment of the pseudorabies virus (PrV) genome identified an open reading frame of 804 bp whose deduced protein product of 268 amino acids exhibited homology to dUTPases of other herpesviruses. The gene was designated UL50 because of its colinearity with the homologous gene of herpes simplex virus type 1. An antiserum(More)
Pseudorabies virus (PrV) is the causative agent of Aujeszky's disease which results in significant losses in pig husbandry. Recently we identified the gene encoding the deoxyuridine-triphosphatase (dUTPase) of PrV as the homolog of the UL50 gene of herpes simplex virus type 1. The PrV UL50 gene product was characterized and a UL50 negative PrV mutant (PrV(More)
Intradermal vaccination with plasmid DNA encoding envelope glycoprotein C (gC) of pseudorabies virus (PrV) conferred protection of pigs against Aujeszky's disease when challenged with strain 75V19, but proved to be inadequate for protection against the highly virulent strain NIA-3. To improve the performance of the DNA vaccine, animals were vaccinated(More)
