Common NameCereulide
DescriptionCereulide is a cyclic peptide and a member of the chemical class of toxins produced by certain strains of Bacillus cereus. Its chemical structure consists of a 3,4-dehydro-2-methyl-3-phenyl-2-pyrrolidinone core, which contributes to its heat-stability and emetic properties. Cereulide is synthesized via a non-ribosomal peptide synthetase pathway, specifically encoded by the cereulide synthetase (ces) genes, which have been identified in various isolates of B. cereus (PMID:40378489 ). This toxin is implicated in foodborne intoxication, particularly associated with rice products, and is linked to severe clinical outcomes (PMID:39631214 ). The biosynthesis of cereulide is often accompanied by other virulence factors such as hemolysins and phospholipases (PMID:40378489 ), and its presence can be detected in food samples, highlighting the pathogen's risk to food safety (PMID:39942077 ). Additionally, cereulide-producing strains exhibit specific toxin types that correlate with complicated clinical disorders (PMID:39849755 ). Recent studies have also explored detection methods targeting ces genes, emphasizing the importance of monitoring these toxins in food safety practices (PMID:40467226 ).
