Abstract:

Bacillus cereus is a common bacterium causing food poisoning,gram-positive opportunistic pathogen,and widely distributing in soil,water and all kinds of food.In recent years,Bacillus cereus also has been found in a variety of animals including people as a zoonotic bacterium.It gives rise to gastrointestinal disease,which leading to diarrhoeal or emetic type of food poisoning.Thus,a rapid and accurate detection is critical for controlling the pollution or the treatment.This study conducted a comprehensive and detailed summary for the detection methods of Bacillus cereus, including conventional detection,conventional PCR,multiplex PCR,Real-time PCR,propidium monoazide-quantitative PCR,droplet digital PCR,ring-mediated isothermal amplification technology and enzyme-linked immunosorbent assay (ELISA).From the traditional method to the emerging technology,involving the traditional detection technology,molecular biology detection and immunological detection technology,the authors described the principle,range and the advantages and disadvantages of each method.Because of the difference in sensitivity,accuracy,sample requirements and so on,the detection methods could be selected according to the requirement and conditions.In the combination of molecular biology methods and immunological methods,the samples are detected from multiple angles and multilevels,and the results can be presented in a comprehensive and convincing manner.Moreover, Bacillus cereus can produce a variety of toxins which determine its pathogenicity.Thus,the detection of toxin contributes to determining the pathogen and its pathogenicity.Overall,as a threat to the health of mammals and humans,rapid and accurate detection of Bacillus cereus can effectively assist treatment and advance prevention.The detection methods were summarized here to contribute a comprehensive and accurate assessment of the risk of Bacillus cereus, and it was respected to provide a scientific evidence to active monitoring and early warning.
