Coinfección de tuberculosis y paratuberculosis en un toro de la Provincia del Chaco, Argentina

Abstract

A case of tuberculosis and paratuberculosis coinfection in a Brangus bull from Basail, Chaco (Argentina) is described. The animal presented typical symptoms of paratuberculosis -diarrhea, weight loss and dehydration- and was diagnosed by delayed hypersensitivity reaction with bovine PPD for tuberculosis, indirect ELISA for paratuberculosis, and necropsy and histopathology. Indirect ELISA resulted positive and delayed hypersensitivity reaction was negative. However, the histopathologic findings in lung and liver samples showed the presence of lesions compatible with tuberculosis, while intestine and mesenteric lymph nodes revealed evidences of paratuberculosis.
