PCR was carried out in a Hybaid
PCR Express Thermal Cycler (Hybaid, UK), and the PCR
reaction mixture (25 μL) contained 12.5 μL of Taq PCR
mastermix (Qiagen GmbH, Germany), 10 pmol of each
primer and 2 μL of DNA template prepared from colonies
or 5 μL of DNA template prepared from T14 enrichment
broth. In order to verify the absence of inhibition or crosscontamination,
S. equisimilis ATCC 10009 DNA or water
were used in each PCR run instead of the template DNA
respectively as positive and negative control samples. PCR
was conducted with the following program: 94oC for 3
min, 35 cycles at 94oC for 30 sec, at 57oC for 30 sec, and at
72oC for 40 sec, followed by a final extension at 72oC for 7
min
