Hydroxyurea-resistant vaccinia virus: overproduction of ribonucleotide reductase.

abstract：:Mice and cattle injected with plasmids encoding bovine herpesvirus 1 (BHV-1) glycoproteins developed gene-specific antibody responses capable of neutralizing BHV-1. The ability of animals to respond serologically to DNA injections was in part dependent on the quantity of DNA injected and was also negatively affected b...
