Abstract:

Bacillus cereus is an opportunistic pathogen which can cause food poisoning, and it is widely distributed in nature. The pathogenic strain and Bacillus anthracis have similar toxins, and the strains that cause poisoning are divided into two categories of vomiting and diarrhea. The study on Bacillus cereus typing has important implications for the tracing and the epidemiological investigation. At present, the popular methods for typing this bacterium are traditional typing methods and molecular typing methods. The traditional typing methods include phage typing, biochemical typing, etc.; and the molecular typing methods include repetitive-element PCR, amplified fragment length polymorphism, whole genome sequencing and so on. This paper took the Bacillus cereus as the test object, reviewed and expounded all the typing methods and the advantages and disadvantages of them, with the aim of providing reference for prevention and control of bacterial disease caused by this bacterium.

Key words: Bacillus cereus, traditional typing methods, molecular typing methods, PCR, matrix-assisted laser desorption ionization time-of-flight mass spectrometry
