Monoclonal antibodies (MAbs) against Pseudorabies virus (PrV) were obtained by the fusion of P3x-Ag8.653 myeloma and spleen cells from immunized BALB/c mice with a suspension of Pseudorabies (PrV) virus strains: MAVE (Morbus Aujeszk'y virus Ercegovac) and NS 257 (Novosadski virus strain). A total of 95 antibody-secreting hybridoma cells against the virus strain (MAVE and NS 257) of Pseudorabies...

We used bacteria-derived bovine alpha-interferon I1 (Bo IFN-alpha I1) to study its antiviral effect in a bovine turbinate cell line on bovine diarrhea virus, infectious bovine rhinotracheitis virus, parainfluenza 3 virus, and pseudorabies virus. We based our study upon replicate tests for each strain by using a block titration system with various concentrations of Bo IFN-alpha I1 against variou...

The gene encoding the pseudorabies virus glycoprotein gp50 was cloned at the very left end of the genome of adenovirus type 5 to give a recombinant adenovirus (Ad-gp50) defective for the E1A gene. Ad-gp50 expressed high levels of gp50 in cells which either complemented (293 cells) or did not complement (Vero and HeLa cells) the E1A gene. Surprisingly, over an extended period, higher levels of g...

Neurotropic herpesviruses exit the peripheral nervous system and return to exposed body surfaces following reactivation from latency. The pUS9 protein is a critical viral effector of the anterograde axonal transport that underlies this process. We recently reported that while pUS9 increases the frequency of sorting of newly assembled pseudorabies virus particles to axons from the neural soma du...

Transsynaptic tracing has become a powerful tool used to analyze central efferents that regulate peripheral targets through multi-synaptic circuits. This approach has been most extensively used in the brain by utilizing the swine pathogen pseudorabies virus (PRV)(1). PRV does not infect great apes, including humans, so it is most commonly used in studies on small mammals, especially rodents. Th...

Genetical and biochemical evidence indicates that herpes simplex virus (types and 2) specifies a unique kinase activity which is able to phosphorylate both thymidine and deoxycytidine. Pseudorabies virus specifies an enzyme which has only thymidine kinase activity and so does vaccinia virus, while equine abortion virus does not induce either activity. It is shown that the HSV specified deoxypyr...

Marek's disease virus (MDV) and pseudorabies virus (PRV) cross-reacted by fluorescent antibody test but not by gel diffusion, virus neutralization, or cross-protection tests. Herpesvirus of turkeys cross-reacted with MDV but not with PRV. Other herpesviruses tested did not have cross-reactions.

Pseudorabies virus-induced cell fusion in rabbit kidney cells can be prevented by Concanavalin A added early after infection. The infected cells are not agglutinated and the infectivity of cell-free virus is not reduced. Sera from productively infected animals also inhibit polykaryocytosis, whereas a hyperimmune serum directed against virus structural components has no effect. 2-Deoxy-d-glucose...
