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.
