Abstract

Flavobacterium indologenes (F. indologenes) has recently been implicated in nosocomial or opportunistic infection, It has been isolated from lids, conjunctiva, and lacrimal system, and is resistant to most antibiotics. No previous cases of F. indologenes keratitis have been reported in the literature. The natural habitat of flavobacteria is soil, water, plants, and foodstuffs. In the hospital environment, these bacteria exist in water systems and wet surfaces. They are not part of the normal ocular flora. Flavobacterium indologenes, (synonymous in the past with F. bastinum, F. gleum, and llb), is strongly pigmented (yellow to orange) and indole positive. Highly notable is the organism's resistance to most antibiotics, It may be sensitive to erythromycin, rifampin, cephaloridine, trimethoprimsulfamethoxazole, and chloramphenicol. Ceftazidime, as a third-generation cephalosporin, has a potent bacteriocidal activity. We present such a case of F. indologenes keratitis with successful treatment with topical ceftazidime.
