  • Strategies for the detection of Escherichia coli

    2004-2-11 · The use of MBs in the detection of E. coli O157:H7 is now beginning to have success and a few papers have been published recently. McKillip and Drake (2000) used a beacon to detect the pathogen in skimmed milk during PCR amplification of DNA. The probe was designed to hybridize to a region of the slt2 gene and to fluoresce when the stem-loop structure became ‘open’ upon hybridization.
