Sensitivity test to detect C. jejuni subsp. jejuni LMG8841T and C. coli JCM2529T by using a real-time turbidimeter and visual assessment. The curves from left to right in panels a and b indicate decreasing concentrations of bacterial DNA (790 to 0.79 CFU per test tube in panel a and 380 to 0.38 CFU per test tube in panel b). (a) Detection of C. jejuni; (b) detection of C. coli; (c) visual detection of C. jejuni and C. coli by observation of turbidity. Tube 1, third sample containing 790 CFU for C. jejuni; tube 2, third sample containing 7.9 CFU for C. jejuni; tube 3, third sample containing 0.8 CFU for C. jejuni; tube 4, negative control; tube 5, third sample containing 380 CFU for C. coli; tube 6, third sample containing 3.8 CFU for C. coli; tube 7, third sample containing 0.4 CFU for C. coli; tube 8, negative control.
