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 systems of adult mice after intranasal inoculation. We
demonstrate that neither of the two glycoproteins is required for
infection of the nervous systems of mice by pseudorabies virus.
