The multiplex PCR method proposed by Park et al. multiplex PCR method for identification ofB. cereus group and individual bacterial species has been proved to be useful only for identification the entire group of B. cereus. This method does not provide specific identification of the individual species. Lack of specificity of the primers used in this study creates a risk of obtaining PCR product in more than one species of the entire examined group of bacteria and does not allow the precise identification to the species level.
