RESUMO
Two mutations affecting herpes simplex virus type 1 glycoprotein B were mapped by marker rescue using cloned sequences of wild-type herpes simplex virus type 1 strain KOS DNA. One mutant, tsB5, is a temperature-sensitive mutant which does not express mature, functional glycoprotein B at the nonpermissive temperature. The other mutant, marB1.1, expresses an antigenic variant of glycoprotein B and was selected for resistance to neutralization by a monoclonal antibody. The mutation in tsB5 mapped to a 1.2-kilobase segment of the herpes simplex virus type 1 genome between coordinates 0.361 and 0.368, whereas the mutation in marB1.1 mapped to a 1.6-kilobase segment between coordinates 0.350 and 0.361. An in situ enzyme immunoassay was used to detect plaques of recombinant wild-type virus among the progeny of transfections with mutant marB1.1 DNA and wild-type DNA fragments.
