Infant botulism. Identification of Clostridium botulinum and its toxins in faeces.

Clostridium botulinum and its toxin were identified in the faeces of four infants, aged 6 to 13 weeks, who had symptoms consistent with botulism. Two cases had type-A toxin and two cases had type-B toxin present in their faeces. No toxin was detectable in sera C. botulinum and toxin could be recovered from faeces more than 8 weeks after admission to hospital. All four cases occurred within a 6-month period. The source of the toxin in these infants may have been in-vivo production from ingested organisms.
