Isolation of Kingella denitrificans from a corneal ulcer.

Purpose: To report a case of a corneal ulcer caused by an unusual pathogen.

Design: Case report.

Methods: Clinical review describing initial presentation, course, and outcome of 1 patient with a corneal ulcer caused by Kingella denitrificans.

Results: A 77-year-old man with a prior history of 4 penetrating keratoplasties in the right eye for herpes simplex virus keratitis presented with a 3-day history of a red painful right eye. On examination, he was found to have a corneal ulcer identified by culture as K. denitrificans.

Conclusions: Although Kingella spp. is not a common ocular pathogen, it can infect the cornea, especially when the host immune defense is altered.
