Abstract:
... Bacillus cereus is a well-known foodborne pathogen capable of causing two types of gastrointestinal diseases, diarrhoea and emesis. It is of particular concern for the food industry causing food safety issues, due to the formation of spores, biofilms and diarrhoea and/or emetic toxins. This review reveals the possible link between two food safety issues – toxins and spores - and the role of biofil ...
