Nontuberculous mycobacterial skin disease in cat; diagnosis and treatment – Case report

Introduction Mycobacterial diseases of humans and animals can be caused by mycobacteria other than tuberculosis (MOTT). The transmission of the infection primarily occurs via the respiratory or oral routes, but also via a damaged skin barrier. MOTT have high resistance to external factors; therefore, infected, undiagnosed animals can pose a risk for public health. Case report The case study describes mycobacterial skin infection in a domestic cat. The correct diagnosis was reached four months after the appearance of the first clinical signs. Those were purulent, granulomatous lesions and fistulas, which could potentially act as a source of the infection for the owners and the veterinarian who cared for the animal. Conclusion Despite using advanced diagnostic techniques, establishing the final cause of the cat’s illness was a lengthy process. The skin lesions could contribute to the transmission of the bacteria in the environment. Non-targeted treatments could also cause antimicrobial resistance.
