A novel micro-PCR-based detection method, termed ultra-rapid real-time PCR, was applied to the development of a rapid detection for Paenibacillus larvae (P. larvae) which is the causative agent of American Foulbrood (AFB). This method was designed to detect the 16S rRNA gene of P. larvae with a micro-scale chip-based real-time PCR system, GenSpector TMC-1000, which has uncommonly fast heating and cooling rates (10 degrees C per second) and small reaction volume (6microl). In the application of ultra-rapid real-time PCR detection to an AFB-infected larva, the minimum detection time was 7 min and 54s total reaction time (30 cycles), including the melting temperature analysis. To the best of our knowledge, this novel detection method is one of the most rapid real-time PCR-based detection tools.
