Seroprevalence of viral agents of the Bovine Respiratory Complex in Creole breeds of the Turipaná Research Center of AGROSAVIA. Rev. mex. de cienc. pecuarias [online]. 2020, vol.11, n.3, pp.771-782.  Epub 05-Fev-2021. ISSN 2448-6698.  https://doi.org/10.22319/rmcp.v11i3.5154.

A descriptive cross-sectional study was conducted in order to determine the prevalence and epidemiological factors associated with viral diseases of the Bovine Respiratory Complex (BRC) in Creole breeds of the Turipaná Research Center - AGROSAVIA (Colombia). A total of 403 cattle of the Romosinuano breed and 445 of Horned Coastal Creole cattle (CCC, Spanish acronym) breeds were evaluated. The presence of antibodies for bovine viral diarrhea (BVD), infectious bovine rhinotracheitis (IBR), parainfluenza-3 (PI3) and bovine respiratory syncytial virus (BRSV) was determined through the indirect ELISA technique. The prevalences were estimated, and the associations between the viral agents and the variables of sex, age, herd type and breed were evaluated. The Chi-square test was applied with a level of 5% significance and the effect of the association was determined by the Odds Ratio (OR). A logistic regression model was constructed to explain the most prevalent disease. The mean prevalences in both breeds were: BVD (33.02 %), BRSV (18.51 %), IBR (12.85 %) and PI3 (11.20 %); however, individually, the CCC breed had a higher prevalence for all diseases. The regression model showed an association between DVB, IBR and PI3, sex, age, females of more than 1 year of age, and the CCC breed. In order to address the diseases of the BRC, it is recommend actions with an emphasis on the control and prevention of BVD and deeper studies to understand the dynamics and co-endemicity of the BVD, IBR, BRSV and PI3 in the breeds studied.
