Abstract
The prevalence of bovine viral diarrhea virus (BVDV) infection was evaluated in 347 criollo cattle of both sexes and older than 6 months of age in small herds of the province of Melgar, Puno. Serum samples were tested for antibodies against BVDV using the viral neutralization test. The 48.7 ± 0.1% (166/347) of the samples had antibodies against BVDV. Animals carrying on the virus virus were not detected. Antibodies were detected in all sampled herds and the prevalence varied from 15.7 to 94.1%. Antibodies titers varied from 2 to >256, showing that BVDV infection is widespread in the local cattle population, suggesting the presence of factors promoting the viral distribution such livestock fairs and lack of control for animal movements within the region.

Bibliographical note
Funding Information:Estudios serológicos realizados en bo- vinos de las principales cuencas lecheras del Perú muestran que el VDVB está amplia-mente difundido, y con prevalencias superio-res al 50% (Contreras et al., 2000; Rivera et al., 2001; Aguilar et al., 2006; Ståhl et al., 2008). A pesar de la importancia socio-eco-nómica del ganado bovino de las zonas andinas y la carencia de restricciones con la DVB para el movimiento interno de los bovi-nos en el país, existe escasa información so-bre la prevalencia de la infección en valles interandinos y zonas altoandinas en donde actualmente existe un creciente interés en el desarrollo de la industria lechera. El objetivo del presente estudio fue determinar la seroprevalencia del virus de la diarrea viral en bovinos criollos de los nueve distritos de la provincia de Melgar, Puno.
