Editor,—Ochrobactrum anthropi is a non-fermentative, motile, strictly aerobic, oxidase positive Gram negative bacillus.1 In 1980, the first case of human infection with O anthropi was described.2 Since then, there have been some reports and this bacillus has been considered as a possible cause of opportunistic infection. There are only two reports ofO anthropi endophthalmitis, one was metastatic endophthalmitis in a patient with a central venous catheter,3 and the other was after cataract surgery.4 We describe a case of unilateral endophthalmitis caused by O anthropi, which was diagnosed after two vitreous surgery procedures.
