Detection of C. jejuni mapA gene copies in soil from experiment A throughout the sampling period of 28 days, with starting inoculation doses of 10⁶ and 10⁷  C. jejuni cells, corresponding to 10⁵ (blue diamonds) and 10⁶ (pink squares) cells g⁻¹ soil. Error bars represent standard deviations from 5 replicate samples and 3 different real-time PCR reactions per replicate.
