Histopathological Examinations of Tuberculosis Cases Detected in Chickens grown by a Family Enterprice

The study material consisted of 22 randomly selected chickens bought from Erzurum animal market place for student practice. There were formations of grey‐yellowish nodules with distinct border lines, in different numbers and diameters on the surfaces of spleen, liver, lung and kidney on necropsie in microscopy. Histopathological examinations of the sections confirmed the lesions as being the nodules of tuberculosis. Indeed, a large number of tuberculosis bacilli were observed on the sections stained by Ziehl‐Neelsen. In the light of these findings, 8 (out of 22) chickens were diagnosed with avian tuberculosis and they were examined further due to their epidemic and zoonotic natures.
