Plain-English summary
A domestic cat was brought to the vet due to serious breathing problems and a swollen belly, which led to the discovery of a lung infection caused by Mycobacterium avium subspecies hominissuis. After confirming the infection through lab tests, the cat was treated with a combination of antibiotics for six months. Although the cat experienced some seizures during treatment, these stopped after adjusting the medication. By the end of the treatment, the cat showed no signs of illness, and the infection was completely cleared.

Abstract
A cat was referred because of diffuse parenchymal lung disease. Close examinations revealed a swollen abdominal lymph node and multiple nodules of the liver. Mycobacterium avium subspecies hominissuis infection was confirmed by culture and single nucleotide polymorphism analysis of samples recovered from the liver and bronchoalveolar lavage. After administration of combination antibiotics for 6 months, culture results were negative. Though atonic seizures were observed during the treatment, it disappeared after isoniazid discontinuation and pyridoxal phosphate administration. On day 771 of illness, no clinical signs, lung diseases, or obvious swelling of lymph nodes was observed. This is the first report to confirm Mycobacterium avium subspecies hominissuis infection in cats through gene analysis and to completely cure it with combination antibiotics.
