Isolation of Ewingella americana from a patient with conjunctivitis.

Ewingella americana (family Enterobacteriaceae) was isolated separately from both eyes of a 30-year-old woman. Clinical signs and symptoms included adhesive eyelids, itching and edematous upper and lower lids. Therapy with amoxicillin-clavulanate resulted in the relief of symptoms. Ewingella americana can be isolated worldwide, but seems to be a rare pathogen.
