Molecular characterization of equine herpesvirus 1 (EHV-1) isolated from cattle indicating no specific mutations associated with the interspecies transmission.

Interspecies trasmission of equine herpesvirus 1 (EHV-1) from horse to cattle was shown by Crandell et al. (1988). Specific mutations related to the transmission were studied by comparison of five EHV-1 isolates in cattle (BH1247, 3M20-3, G118, G1753, and 9BSV4) using polymerase chain reaction and restriction fragment length polymorphism analysis with added sequencing.
