    Botulism B food poisoning causes acute eye and dry mouth symptoms. Guanidine treatment improved patient outcomes, while antitoxin was ineffective in later stages.

    Area of Science:

    • Neurology
    • Toxicology
    • Ophthalmology

    Background:

    • Botulism is a rare but serious paralytic illness caused by toxins produced by Clostridium botulinum bacteria.
    • Foodborne botulism results from consuming contaminated food, leading to intoxication.
    • Clostridium botulinum type B is a common cause of botulism in certain regions.

    Observation:

    • Nine patients with food poisoning due to botulism B infection presented with acute symptoms.
    • Prominent clinical findings included accommodation paresis, mydriasis (dilated pupils), and dry-eye symptoms.
    • Impairment of salivary secretion, affecting cholinergic autonomic innervation, persisted for months.

    Findings:

    • Guanidine hydrochloride demonstrated a beneficial effect in treating the observed symptoms.

  • Late-stage administration of antitoxin proved ineffective in this cohort of patients.
  • Cholinergic autonomic dysfunction was a significant and prolonged feature of botulism B.

    • Implications:

    • Guanidine may be a viable therapeutic option for managing acute botulism B symptoms, particularly autonomic dysfunction.
    • Early diagnosis and intervention are crucial for effective botulism treatment.
    • Understanding the long-term effects of botulism B on autonomic function is important for patient management and recovery.
