The aim of the study was to determine the causative factor of a suppurating wound in the area of the hock joint of the left limb of the dog. The material for the study consisted of tissue fragments from the diseased site on the dog's hind limb. Pus from the diseased site and dressing materials used during the surgical procedure were also examined. Laboratory diagnostics were performed according to the methodology of isolating bacteria from the Mycobacterium genus. Molecular testing consisted of the Hain test and the spoligotyping method. The isolated strain was classified as Mycobacterium tuberculosis with spoligotype T1 926.

The results obtained in both the imaging diagnostics and the microbiological examination allowed for the diagnosis that the dog was suffering from a multi-organ tuberculosis (TB). TB caused by M. tuberculosis in a dog is a typical example of anthropozoonosis. In the described case, the infection most likely occurred through the consumption of infected human sputum. Mycobacterial infections in dogs are often overlooked in veterinary practice, despite being a potential source of infection for other animals and humans. This case is the first animal in Poland with diagnosed tuberculosis in which a decision was made to treat it. The dog has been undergoing anti-tuberculosis therapy according to the Engelman et al. regimen for 2 years. Currently, the dog is taking only one anti-tuberculosis drug and the prognosis for this patient is good.
