In the Gdańsk Zoo a case of a disease induced by Mycobacterium bovis was recorded in a twelve-year-old male Defassa Waterbuck. The main symptom of the disease was persistent cough. The animal died as a result of anesthesia administered for the purpose of carrying out an intradermal TB test. The autopsy showed an advanced stage of pneumonia with multiple disseminated, partially purulent, partially calcified tubercles in both lungs and mediastinal lymphadenitis. Samples of the lung tissue and lymph nodes were sent to a laboratory for examination. During bacterioscopy, acid-fast bacilli were recognized. The culture and genotype identification revealed that the infection had been caused by Mycobacterium bovis ssp. bovis.
