Seroprevalencia de pestivirus de rumiantes en ovinos reproductores de una empresa de la sierra central del Perú

The aim of the present study was to determine the prevalence of Bovine Viral Diarrhea Virus (BVDV) and Border Disease virus (BDV) in breeding sheep from a large cooperative farm in the Central highlands of Peru. Blood samples from apparently healthy sheep of 4 years old, both sexes (female = 165; male = 165) were collected for antibodies detection against BVDV and BDV using the virus neutralization test. The 2.1 ± 1.5% (7/330) and 28.5 ± 4.9% (94/330) of breeding sheep had antibodies against BVDV and BDV respectively, with antibodies titers of 1:2 and 1:16. There was significant association between sex and presence of antibodies against BDV (females: 53.3 ± 7.6%; males: 3.6 ± 2.9%) (p\u3c0.05)

Seroprevalence of ruminant pestivirus in breeding sheep in the central sierra of Peru

El objetivo del presente estudio fue determinar la frecuencia de los virus de la Diarrea Viral Bovina (VDVB) y de la Enfermedad de la Frontera (VEF) en ovinos reproductores procedentes de una empresa ovejera de la sierra central del país. Se colectaron muestras de sangre de ovinos reproductores hembras (n=165) y machos (n=165) aparentemente sanos, con un promedio de edad de cuatro años, y criados en forma extensiva. Los anticuerpos contra VDVB y VEF se detectaron mediante la prueba de neutralización viral. El 2.1 ± 1.5% (7/330) y 28.5 ± 4.9% (94/330) de ovinos reproductores tuvieron anticuerpos contra el VDVB y VEF, respectivamente, con títulos de anticuerpos de 1:2 a 1:16. Se encontró asociación significativa entre el sexo del animal y la presencia de anticuerpos contra el VEF (hembras: 53.3 ± 7.6%; machos: 3.6 ± 2.9%) (p<0.05).The aim of the present study was to determine the prevalence of Bovine Viral Diarrhea virus (BVDV) and Border Disease virus (BDV) in breeding sheep from a large cooperative farm in the central highlands of Peru.
