ABSTRACT
Infant botulism (IB) results from absorption of heat-labile neurotoxin produced in situ by
Clostridium botulinum that can colonize the intestines of infants younger than one year (1). It is
an age-limited neuromuscular disease that is distinct from classic botulism in that the toxin is
elaborated by the organism in the infant’s intestinal lumen and is then absorbed.
