Abstract

A survey of bovine viral-diarrhoea virus (BVDV) infection was carried out in a non-vaccinated cattle population from the Asturias region of Spain in 1997 to assess seroprevalence and identify risk factors associated with infection. Twenty-eight herds were included; 529 cows were bled. Information regarding the herd and each animal sampled were recorded through a personal interview with the farmer. The true prevalence was estimated to be 21%. According to the antibody-age profiles and the herd-management characteristics, no persistently infected animals were suspected at that time within the herds sampled. Random-effects logistic regression found two major factors associated with seropositivity: age and cow origin. Results suggested that BVDV infection could be controlled in that area by livestock-trade control (without vaccines). In addition, an increasing risk of abortion was not observed when cows were seropositive to both BVDV and Neospora caninum infections. (C) 2001 Elsevier Science B.V. All rights reserved.
