Objective Bovine Viral Diarrhoea (BVD) is a cosmopolitan disease caused by a pestivirus responsible for various pathological disorders such as digestive, respiratory and genital syndromes and of a debilitating subclinical chronic form. Its main characteristic is a conspicuous immunodepressive action in the host. Recent findings in our laboratory indicate that: - in man there is a prevalence of specific antibodies against BVD virus, particularly to the non-cytopathic (NCP) strains - the contact with susceptible animals is probably an important epidemiological factor - transmission to man seems to be a world-wide phenomenon - antibody specificity is confirmed by Western Blotting Test (WBT) - the screening in AIDS patient groups showed slight higher prevalence for BVDv - in a first screening of 60 samples, a NCP strain was isolated in 2 buffy coats and recognized by specific anti-BVD sera The purpose of the proposed research is: - the further optimization of WBT for BVD virus as reference test for serology in man - screening on human sera in Europe and Zambia with IIF and confirmation with WBT - isolation of Bvdv in human buffy coat samples - characterization of virus isolates - evaluation of an eventual etiopathogenic role on diarrhoea, especially in neonates, and genital disorders in man - comparative study of double infected patients and patients with only HIV infection in order to evaluate the possible interaction of BVD infection with the evolution of HIV infection.
