Tuberculosis in geese (Anser anser) in Turkey

Tuberculosis was detected in seven geese at the breeding unit of the Faculty of Veterinary Medicine, Kafkas University, during 1998. In the necropsy, lesions of nodular type were seen in the liver, spleen, and lungs. Histopathologically, the lesions were characterized by central areas of caseous necrosis surrounded by epithelioid cells, multinucleated giant cells, lymphocytes, and an outer fibrous capsule. Acid-fast bacilli were visualized by the Ziehl-Neelsen staining method in paraffin sections and smears. Inoculation into Löwenstein-Jensen media with glycerin yielded Mycobacterium spp.
