Resumo
One of the limiting factors of productive efficiency in cattle and buffalo herds is related to the high prevalence of infectious diseases which affect reproduction. The aim of this study was to determine the prevalence of anti-Leptospiraantibodies for bovine viral diarrhea virus (BVDV) and bovine herpesvirus type 1 (BoHV-1) in bovine and buffalo herds in Colombia. Blood serum samples were collected from 1100 buffaloes and 1000 cattle. The ELISA technique was used to detect antibodies against BVDV and BoHV-1, and the microscopic agglutination technique to detect anti-Leptospiraantibodies. The prevalence of anti-Leptospiraantibodies and of BVDV and BoHV-1 in bovine samples was observed in 16, 39.7, and 65% of animals, respectively, while the positivity in samples for the same antibodies in buffalos was detected in 18.7, 27.5 and 51.5%, respectively. Exposure of cattle and buffaloes to BoHV-1 was positively associated with age, higher prevalence rates were observed in older ages. Seropositivity of cattle for BVDV and BoHV-1 was higher in male animals. Activities such as embryo transfer, milking, and needle reuses, as well as the presence of cats and rodents are factors which favor positivity of the herd for BVDV and BoHV-1.(AU)
