[0009] In order to solve the problems of the prior art, the present invention is to provide a multiplex PCR to detect foodborne pathogens fourteen primer sets and kits for quick screening of these fourteen food source of pathogens, to establish a common PCR multiplex PCR platform.
[0010] In order to achieve the purpose of the present invention, the present invention provides a first technical design and selection of specific primers and a multiplex PCR detection of foodborne pathogens primer sets:
[0011] 1, build positive internal control (IAC) primers and templates
[0012] pET28a plasmid as a template to design a pair of primers which 1176bp fragment size, as the detection of I AC. I AC upstream primer sequence 5 '-TGCAGGTCGACTCTAGAGGA-3', the sequence I AC downstream primer is 5 '-TTCGAGCTCGGTACCCGGGGA-3'. pET28a nucleotide sequence as shown in SEQ ID N0.31.
[0013] 2, screening different bacteria-specific genes or DNA fragments used for primer design
[0014] The present invention literature analysis and testing requirements analysis, obtained for each candidate pathogens amplified gene or DNA fragment (see Table 1).
