FIG. 1.

Representative standard curve for detection of formalin-killed C. jejuni using PCR combined with avidin capture assay. PCR products were labeled by incorporation of FL-11-dUTP. Cell numbers were based upon visual counts prior to serial dilution. The average absorbance reading for the negative control (OD at 405 nm [OD₄₀₅] = 0.014) was eightfold less than the reading for the 1-cell/ml sample.
