Long-term viral serology of semi-free-living and captive ungulates.
Between 1973 and 1994, blood samples were collected at Whipsnade Wild Animal Park (UK) from three ungulate species kept in enclosures, including 28 European bison (Bison bonasus), 37 scimitar-horned oryx (Oryx dammah), and 49 Père David's deer (Elaphurus davidianus), and also from 144 semi-free-living Chinese water deer (Hydropotes inermis). These samples were tested for the presence of antibodies against three bovine viral diarrhea virus (BVDV)-like strains, three alpha-herpesvirus strains, enzootic hemorrhagic disease virus (EHDV) of deer, bovine respiratory syncytial virus (BRSV), bovine adenovirus 3 (BAV-3), and enzootic bovine leucosis virus (EBLV). Thirty-three individuals (13.1%) had antibodies to one or more of the three BVDV-like viruses, with titers ranging from 1:5 to 1:16, and 17 individuals (6.6%) were positive for antibodies to one or more of the three alpha-herpesviruses, with titers between 1:4 and 1:80. The highest titers and greatest proportion of seropositivity were against SH9/11, a recently isolated cytopathogenic pestivirus from wild roe deer (Capreolus capreolus). There were no positive reactors to BRSV and EHDV, and there was only one BAV-3 positive reactor, a scimitar-horned oryx, and one EBLV reactor, a European bison. There is no serologic evidence that semi-free-ranging Chinese water deer are important reservoirs or transmitters of the viral diseases investigated.
