Two large outbreaks of diarrheal illness associated with Cyclospora cayetan
ensis, a coccidian parasite, provided an opportunity to evaluate clinical s
yndromes associated with this enteric pathogen. Reiter syndrome, a triad of
ocular inflammation, inflammatory oligoarthritis, and sterile urethritis,
has been associated with enteric infections. We describe the first case of
Reiter syndrome following protracted symptoms of Cyclospora infection.
