ABSTRACT
Restriction fragment length polymorphisms (RFLPs) were detected within BHV1.1, BHV1.2, and BHV5 genomes using the restriction enzyme PstI. The genomic areas of these changes has not been previously reported. Using Southern blot hybridization with DNA probes representing the entire genome of BHV1.1, areas of genomic variation were located for a respiratory isolate (BHV1.1), four vaccine isolates (BHV1.1), a genital isolate (BHV1.2), and two encephalitic isolates (BHV5). The most frequently observed RFLPs of BHV1.1 and BHV1.2 occurred within the internal repeat region and the left terminus of the unique long region. When two separate isolates of the encephalitic BHV5 were compared, RFLPs were detected in the internal and right terminal repeat regions. These are the regions of each genome from which immediate early genes are transcribed. No genomic variation was observed throughout the unique long and unique short regions for all BHV1 and 5 isolates examined.
