A 31-year-old woman presents with acute ascending paralysis and areflexia. Vital signs show HR 92/min, BP 138/84 mmHg, RR 18/min, temperature 37.2°C, SpO2 98% on room air. Cerebrospinal fluid analysis reveals protein 85 mg/dL with normal white blood cell count and normal glucose. Electromyography shows demyelinating changes. She denies recent fever. Which of the following infectious agents most commonly precedes this disorder?

  1. A)Treponema pallidum
  2. B)Clostridium botulinum
  3. C)Campylobacter jejuniGABARITO
  4. D)JC virus
  5. E)Corynebacterium diphtheriae
