Abstract

© 2000 Universidad Nacional Mayor de San Marcos. All rights reserved. The prevalence ofbovine viral diarrhea (BVDV) using milk samples of dairy cows ofThe Mantaro Valley, Junin was determined. Milk (n=228) and blood samples (n=65) were taken from cows from 18 herds for detection of antibodies against BVDV by an índirect ELISA and neutralisation tests. The prevalen ce of BVDV was 72.4 % ( 165/228 ). The optical densities of the samples ranged fron O to 2.4. All the herds sampled contained reactors to BVDV with prevalence between 9.4 to 100%. The high prevalence of BVDV confirms its wide distribution in dairy herds in The Mantaro Valley. The concordance high between the indirect ELISA and virus neutralisation tests for detecting antibodies against BVDV in milk and serum samples respectívely, indicate that the indirect ELISA in milk samples could replace the virus neutralisation test for epidemiological studies on BVD.
