A hypothesis concerning Clostridium perfringens type A enterotoxin (CPE) and sudden infant death syndrome (SIDS).

This study identifies the presence of Clostridium perfringens type A enterotoxin (CPE) in some gastrointestinal and serum samples from babies who had died of the Sudden Infant Death Syndrome (SIDS) and other causes. On occasion antibodies to this toxin were identified in sera. CPE is parasympathomimetic in its action. In the adult food poisoning model it is produced when the organism sporulates in vivo. This leads to speculation as to whether this toxin may play an ante-mortem role in the dying process of infants, either in the agonal stages or as a causative factor in SIDS.
