Restriction of bovine herpesvirus 1 (BHV-1) growth in non-permissive cells beyond the expression of immediate early genes.
Mouse BALB/3T3-A31-1-1 (A31) cells are non-permissive to bovine herpes virus-1 (BHV-1) but permissive to pseudorabies virus (PrV). The promoter activity of the immediate early gene of BHV-1 (BICP4) was very weak when compared with that of PrV in A31 cells. Infectious BHV-1 genomic DNA co-transfected into A31 cells with plasmids expressing BICP4 and BICP0 by a strong promoter failed to yield any progeny virus. Growth of BHV-1 in non-permissible A31 cells is restricted in many phases of the growth. The fact that expression of BICP4 and/or BICP0 in A31 cells does not improve the yield of progeny virus from infectious BHV-1 genomic DNA suggests that some more growth restrictions exist beyond the expression of BHV-1 immediate early proteins.
