Canaliculitis caused by Enterobacter cloacae: report of a case.

A 65-year-old man developed canaliculitis first of the left lower and later of the left upper lacrimal canaliculus. Mucoid material expressed from the upper canaliculus grew a pure culture of Enterobacter cloacae, the colonies of which had a stringy, tenacious, mucoid property consistent with the clinical findings. Treatment with topical chloramphenicol and oral ampicillin was followed by complete resolution.
