title: First report of an infant botulism case due to Clostridium botulinum type Af.
abstract: Most infant botulism cases worldwide are due to botulinum toxin types A and B. Rarely, Clostridium botulinum strains that produce two serotypes (Ab, Ba, and Bf) have also been isolated from infant botulism cases. This is the first reported case of infant botulism due to C. botulinum type Af worldwide.
