Occasionally, in cats and dogs various saprophytic mycobacteria including the M. fortuitum - M. chelonei complex, M. smegmatis, M. xenopi and M. phlei have been isolated from:
- superficial or, rarely, deeper persistent abscesses;
- ulcerative lesions; or
- granulomatous lesions.
Treatment is by surgical removal/drainage combined with antibiotics. Gentamicin (2 m/kg IM or SC twice daily) or potentiated sulphonamides (10-15 mg/kg twice a day) are sometimes useful as the usual anti-tuberculous antibiotics are usually ineffective. Treatment is apparently more likely to be successful in dogs than in cats.
