Plain-English summary
A horse was diagnosed with a rare infection caused by Mycobacterium intracellulare, which is a type of bacteria that can lead to disease but is not commonly seen in horses. This particular case showed up as a growth in the horse's nose, known as a granulomatous nasal mass. While mycobacterial infections in horses usually affect the gut or lungs, this is the first time M. intracellulare has been reported in a horse. The treatment details and outcome were not provided, but it's important to discuss any unusual symptoms with your veterinarian.
Abstract
Mycobacterial infections in horses are uncommon, but are caused most frequently by Mycobacterium bovis of the Mycobacterium tuberculosis complex or Mycobacterium avium of the M. avium complex. Disease caused by Mycobacterium intracellulare, the second most common species within the M. avium complex, has not been reported in horses to date. Mycobacteriosis in horses most often presents as enteric, pulmonary or, rarely, systemic disease. Here we report a case of M. intracellulare infection in a horse presenting as a granulomatous nasal mass.
