Mycobacterium szulgai keratitis.

N ontuberculous mycobacteria rarely cause keratitis. Most reported cases have been described in compromised corneas (ie, after penetrating keratoplasty, refractive surgery, and contact lens wear). The most frequently recovered nontuberculous mycobacteria are the rapid growers, Mycobacterium fortuitum and Mycobacterium chelonae. Occasional cases of keratitis caused by the slower-growing Mycobacterium gordonae have also been described. To our knowledge, this is the first reported case of Mycobacterium szulgai keratitis.
