Seroprevalence to Mycobacterium avium subsp. paratuberculosis in the colombian creole cattle Romosinuano and costeno con cuernos

Objective. Determine the seroprevalence and epidemiological factors associated with Mycobacterium avium subsp. paratuberculosis (MAP) in two Creole cattle breeds of the Turipan6 research center - AGROSAVIA. Materials and methods. A cross-sectional epidemiological study was conducted,a total of 848 Creole bovine animals were sampled, 403 Romosinuano and 445 Costello Con Cuernos (CCC); for the serological diagnosis of antibodies, the Elisa Indirect test was used with the commercial kit Parachek (R) 2 by Prionics. The variables sex, age, breed and herd type were the epidemiological factors evaluated and correlated with the presence of antibodies against MAP; the statistical association was established using the Odds Ratio and a multivariate logistic regression model, employing a significance level with p<0.05. Results. The general seroprevalence of the Creole cattle to MAP was 2.35% (95% CI, 1.34-3.38); however, in the Romosinuano it was 0.74% and in the CCC it was 3.82%, being this difference statistically significant (p=0.003). Furthermore, employing a univariate way analysis, females and animals older than one year of age were more affected. The multivariate analysis identified the breed and sex variables as epidemiological factors. Conclusions. In the Creole breeds of the AGROSAVIA-Turipana research center, MAP seroprevalence was low; however, in the Costelio Con Cuernos breed, the risk of contracting the disease is six times higher than in the Romosinuano breed. Moreover, it was shown that females have a higher risk of acquiring the disease.
