Corneal ulceration secondary to intestinal Shigella sonnei
D. L. Roper
A 34-month-old boy had a corneal ulcer due to Shigella sonnei. To my
knowledge, this is the first documented case reported where the same
organism was recovered from the stool. One other case of S sonnei and two
cases of S flexneri corneal ulcers have appeared in the literature. All
cases have been in young black boys between the ages of 23 months and 6
years. The exact pathogenesis remains unclear, but direct fecalocular
inoculation into a preexisting epithelial defect, a probable herpetic
dendrite in this case, is most likely.
