Paratuberculosis is an important disease of cattle in the state of Paraíba, northeastern Brazil. In the Veterinary Hospital of the Federal University of Campina Grande, five outbreaks of paratuberculosis were diagnosed in the last four years. The objective of this paper is to report the frequency of antibodies against paratuberculosis in different regions of the state of Paraíba, in farms with previous diagnosis of the disease and in farms without diagnosis. The prevalence of antibodies against paratuberculosis, examined by ELISA, in two farms with cases of the disease, was of 72.22% (13/18) and 68.75% (11/16), respectively. Serum samples from 486 healthy cattle from 36 farms without paratuberculosis diagnosis, from three different regions of Paraíba (sertão, cariri, and agreste), were also examined by ELISA. The frequency of antibodies was 10.08±1,07% (49/486). Antibodies against paratuberculosis were found in 21 (58.33%) out of 36 farms examined. These results suggest that paratuberculosis is an important disease of cattle in the state of Paraíba and that control measures to decrease the prevalence of the disease are necessary. |
