Development of real-time PCR assays for detection and quantification of Bacillus cereus group species: differentiation of B. weihenstephanensis and rhizoid B. pseudomycoides isolates from milk.

Quantitative real-time PCR (qRT-PCR) offers an alternative method for the detection of bacterial contamination in food. This method provides the quantitation and determination of the number of gene copies. In our study, we established an RT-PCR assay using the LightCycler system to detect and quantify the Bacillus cereus group species, which includes B.
