[Simplified identification and differentiation of feline, canine and phocine herpesvirus isolates using monoclonal...

Infections by alpha-herpesviruses of dogs (canid herpesvirus, CHV) and cats (felid herpesvirus, FHV) are widespread in these species and are of significant clinical relevance. Immunologically closely related herpesviruses have been isolated from harbour seals (Phoca vitulina) showing respiratory disease, hepatitis and/or encephalitis. These isolates are currently referred to as phocid herpesviruses (PhHV). The host spectrum of CHV and FHV, respectively, appears to be restricted to members of the Canidae and Felidae families. Seal herpesviruses, in contrast, cross species barriers, at least in vitro where they productively replicate also in cells of felid origin. Whether cats are susceptible to natural PhHV-infections remains to be elucidated. A reliable etiological diagnosis of acute herpesvirus-associated infections should be desirable especially in breeding kennels and zoos where hosts susceptible for FHV, CHV oder PhHV are reared. For a rapid and unambiguous identification and differentiation of herpesvirus isolates derived from felids, canids and pinnipedia a simple enzyme immunoassay employing monoclonal antibodies is presented.
