Antigenic and nucleotide characterization of a herpesvirus isolated from Pacific harbor seals (Phoca vitulina richardsii)

Summary

This report describes the antigenic and nucleotide characterization of a herpes-like virus that has been isolated from the adrenal tissues of neonatal Pacific harbor seals. Infection with this virus has been previously implicated as a major cause of death of animals undergoing rehabilitation. Comparison and phylogenetic analysis of sequenced fragments of the DNA polymerase, glycoprotein B and glycoprotein D genes, and immunofluorescence assay using herpesvirus-specific monoclonal antibodies, demonstrated close similarity of the Pacific harbor seal herpesvirus to European isolates of phocid herpesvirus-1 (PHV-1) and other α-herpesviruses affecting terrestrial carnivores.
