Perú [online]. 2022, vol.33, n.2, e20694.  Epub 01-Abr-2022. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v33i2.20694.

The aim of this study was to determine the prevalence of bovine viral diarrhoea (BVD), bovine neosporosis (NEOS), enzootic bovine leukosis (EBL) and bovine paratuberculosis (BP) in dual-purpose cows reared under low-tropic conditions. The study was carried out at La Pintada farm located in the municipality of Puerto Boyacá, Boyacá, Colombia, taking blood samples from 840 2-3-year-old cows collected from various departments of the country. Competitive (BVD, NEOS, EBL) and indirect (BP) ELISAtests were performed. Aseropositivity of 25.83% to BVD, 16.29% to NEOS, 14.64% to EBL and 4.17% to BP was found.
