Isolation of a herpesvirus serologically related to bovine herpesvirus 1 from a reindeer (Rangifer tarandus)

Abstract

Serological evidence of exposure of reindeer (Rangifer tarandus) to a virus related to bovine herpesvirus 1 (BHV1) (Synonym: Infectious bovine rhinotracheitis (IBR) virus) has been reported in Canada (El Azhary 1979) and the USA (Dieterich 1981). A serological survey conducted in Finnish Lapland also detected neutralising antibodies to BHV1 in reindeer sera; 23 % of 300 reindeer had detectable antibodies, whereas none of 300 cattle sera from the same region contained antibodies to BHV1 (Ek-Kommonen et al. 1982). There is currently no evidence of BHV1 infection of cattle in Finland, so the isolation and characterisation of the reindeer herpesvirus was of considerable interest. This short communication describes the isolation and preliminary characterisation of a herpesvirus from a reindeer following the administration of dexamethasone.
