Calves latently infected with the 51g mutant did not reactivate from latency because virus shedding did not occur in ocular or nasal cavities.

The virulence and immunogenicity of these mutants were evaluated in specific-pathogen-free calves. Except for the gC deletion mutant, all mutants were significantly less virulent than the parental wild-type (wt) BHV1 strain Lam.
