Bovine viral diarrhoea virus (BVDV) causes significant economic and production losses in cattle worldwide
The results indicate that it is unlikely that BVDV is widely circulating within the wild deer population and unlikely that persistently infected deer are present in the populations surveyed
These results suggest that wild deer are unlikely to be a significant reservoir of BVD infection in cattle
Summary
Bovine viral diarrhoea virus (BVDV) causes significant economic and production losses in cattle worldwide. BVDV-like viruses were isolated from European Bison (Bison bonasus), Pére David’s deer (Elaphurus davidianus), Chinese water deer (Hydropotes inermis) and Scimitar Horned Oryx (Oryx dammah) at Whipsnade zoo between 1973-1994, origin and strains of virus were not reported [21] (Frolich and Flach, 1998) It has been shown, experimentally, that if deer are infected during early gestation they can give birth to PI fawns that may act as a reservoir of infection in the same manner as PI cattle (2224). The experimental production of PIs within deer demonstrates the possibility that BVDV may be retained within the deer population and could potentially be transmitted back to cattle (spill-back event) This suggests that wildlife could play a role in BVDV dynamics in cattle and may need to be considered in control plans [9]. This study surveyed serum samples taken from 596 culled wild deer from England and Wales, between 2009-2010, for the presence of BVD antibodies
