Who is affected by infant botulism?

• A. Adults with altered GI anatomy
• B. Children aged 5-10
• C. Infants under one year old
• D. Teenagers

Answer: (C)

Infant botulism occurs in babies because their gut is still developing its normal bacterial defenses. When a baby under one year swallows spores of Clostridium botulinum, those spores can germinate in the immature intestine and produce toxin there. This in vivo toxin production leads to the neurologic symptoms seen in infant botulism. In older children and adults, the gut environment and established flora usually prevent such colonization, so infant botulism is not typical in those age groups. A common exposure linked to this condition is honey, which can contain the spores.
