Prevalence of goat tuberculosis in Barranca, Peru

The objective of the present study was to determine the prevalence of goat tuberculosis in districts of the Barranca province, Lima (Paramonga, Pativilca, Barranca and Supe). The unique intradermal test of tuberculin using bovine purified protein derivative (PPD), based on the delayed hypersensitivity reaction was used. A total of 412 criollo goats, older than two months of age, reared in an extensive system, were tested. The antigen was inoculated in the caudal fold of the tail and the reaction was observed 72 hours later. Two animals were positive, determining a prevalence of 0.48 ± 0.67%. The results suggest that tuberculosis is scarcely spread in goats of the Barranca province.
