Abstract
Eleven European isolates of Suid herpesvirus type 1 (SHV-1) were compared by restriction fragment pattern analyses and Southern blot hybridization using different genomic probes. The presence of strain discriminative 4 major genome types and several subtypes as well as the molecular distinctions between these were demonstrated. Evolutionary relationships between the different types are suggested on the basis of homologous restriction fragment length polymorphisms.
