摘要：
Aims: The design of a fast, sensitive and specific detection method for Bacillus licheniformis, members of the 'B. cereus group' and B. fumarioli in gelatine. Methods and Results: Specific Taqman probes were designed and tested in a real-time PCR setting. A specific fluorescent signal could be obtained for all gelatine isolates attributed to these species in one single real-time PCR reaction. After sample preparation, a gelatine sample spiked with 1 CFU provided enough template DNA for a significant signal. Conclusion: The potential of a real-time PCR assay for simultaneous detection of B. licheniformis, members of the 'B. cereus group' and B. fumarioli in gelatine is demonstrated. Significance and Impact of the Study: Implementation of the assay in gelatine producing plants may shorten delivery terms and inform on hazards to public health and suitable remediation procedures.
