Seroprevalencia de Mycobacterium avium Subsp. paratuberculosis (MAP) en una granja de ganado de carne de bosque húmedo tropical en Caucasia, Antioquia, Colombia

The present study determines the seroprevalence of MAP in beef cattle of a farm in tropical moist forest located in the municipality of Caucasia. Blood samples from all animals over two years of age (n=151) were obtained together with information on the epidemiological characteristics of the animal (age, breed, sex, parity, reproductive state, days postpartum). Serum samples were analyzed with an Enzyme-Linked Immunosorbent Assay (ELISA) and the information analyzed using descriptive and analytic statistics (two-way frequency tables). ELISA results showed a seroprevalence of 33.8% (IC 95% 26.1-41.4) showed statistically significant association between ELISA results and breed. According to the results, high seroprevalence of paratuberculosis level was determined in a beef farm for the first time in Colombia. Further studies on beef cattle herds should be carried out to increase the knowledge of the prevalence of this disease in the country.
