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 biofilms. The review highlights genetic determinants that are involved in sporulation, toxin production and biofilm formation based on current research, and evidence showing the possible correlation of spore, toxin and biofilm formation of B. cereus. This is the first review highlighting the potential relationship between toxin production and biofilm formation in B. cereus.
蜡样芽胞杆菌是一种众所周知的食源性致病菌，能够引起两种类型的胃肠道疾病，即腹泻和呕吐。由于形成孢子、生物膜以及产生腹泻和/或呕吐毒素，它尤其令食品行业关注，引发食品安全问题。本综述揭示了两个食品安全问题——毒素和孢子——以及生物膜的作用之间可能存在的联系。本综述根据现有研究强调了参与芽孢形成、毒素产生和生物膜形成的遗传决定因素，并提供了证据表明蜡样芽胞杆菌的孢子、毒素和生物膜形成之间可能存在相关性。这是首次强调蜡样芽胞杆菌中产毒与生物膜形成之间潜在关系的综述。
