FIG. 5.

Performance of immunocapture PCR with spiked chicken skin wash (0.5 g of skin/ml of PBS). Based upon analysis of readings by Student's t test (one-tailed hypothesis), a signal could be achieved from a single cell per ml of sample (0.025 < P < 0.010). The coefficients of variation for replicates ranged from 8 to 24%. The average reading for the 0-cell control was 0.109. OD₄₀₅, optical density at 405 nm.
