We report a case of botulism in a 54-hour-old infant with rapidly progressive fulminant paralysis and rapid spontaneous recovery atypical for infant botulism. Clostridium baratii and type F botulinum neurotoxin were isolated from the patient's stool. This unique presentation with rapid recovery is consistent with pharmacokinetics of type F botulinum neurotoxin. Interestingly, a muscle biopsy also revealed pathologic changes early in the disease course. This article reports the youngest known case of infant botulism and only the third reported case of this disease caused by type F neurotoxin. Botulism should be considered in patients of any age with subacute or acute neuromuscular weakness.

Background: Botulinum neurotoxins (BoNTs), produced by , are potent protein toxins that can cause botulism, which leads to death or neuroparalysis in humans by targeting the nervous system. BoNTs comprise three functional domains: a light-chain enzymatic domain (LC), a heavy-chain translocation domain (HC), and a heavy-chain receptor-binding domain (HC). The HC domain is critical for binding to neuronal cell membrane receptors and facilitating BoNT internalization via endocytosis.

What Is Already Known About This Topic?: Foodborne botulism is caused by botulinum neurotoxin (BoNT). () is a strictly anaerobic, Gram-positive bacterium, which is a key pathogen capable of producing BoNT. BoNTs can be classified into seven serotypes (A to G) based on their antigenic properties.
