Abstract

• Ten cases of Azotobacter keratitis were identified at the Baylor College of Medicine and Cullen Eye Institute, Houston, from 1972 to 1980. Azotobacter are large, pleomorphic, aerobic, Gram-negative rods of the family Azotobacteraceae. The genus comprises four species (A beijerinckii, A chroococcum, A paspali, and A vinelandii) that are found in soil and water throughout the world. To our knowledge, Azotobacter species have not previously been recognized as causing human, animal, or plant disease. On the basis of the similarity of the organisms, other cases of Azotobacter keratitis may have been identified erroneously as Moraxella species.
