ABSTRACT
Nine ts mutants of pseudorabies virus (PRV) strain BUK were isolated following bromodeoxyuridine (BUdR) or NaNO2 mutagenesis by a selection technique based on a shiftdown from nonpermissive to permissive temperature. This technique is described and its advantages are discussed. The nine ts mutants have been assigned to four complementation groups.
