Ocular mycobacteriosis—dual infection of M. tuberculosis complex with M. fortuitum and M. bovis

Background We report unfavorable outcome in a patient with subretinal granuloma caused by dual infection of Mycobacterium tuberculosis complex with Mycobacterium fortuitum and Mycobacterium bovis in an immunosuppressed, non-HIV patient. We did a systematic review of literature on dual infection due to M. tuberculosis and M. fortuitum via MEDLINE and PUBMED and could not find any case reported of causing this kind of dual infection in the eye.
