Guillain–Barré syndrome after cyclospora infection

We present a patient who developed Guillain–Barré syndrome (GBS) after a Cyclospora‐induced diarrheal illness. We raise the possibility that Cyclospora is an infectious trigger for GBS in this patient. An active search for this agent in patients with GBS preceded by diarrheal illness is recommended. © 1998 John Wiley & Sons, Inc. Muscle Nerve 21:669–671, 1998.
