All sampling days are indicated as numbers in the table. Shaded boxes display from which days data were included in each mean value used for statistical analysis. For experiment 1, two mean values were calculated from the fecal cfu count of each of the 30 birds. Mean1 was based on data from all sampling days and mean2 was based on data from week two and three. For experiment 2, two mean values were calculated from the fecal cfu counts of each of the eight birds. MeanB was based on data from the first four days after introduction of the first C. jejuni strain in experiment 2a and 2b, respectively, and meanC was based on data from the first four days after introduction of the second C. jejuni strain.
No samples were obtained on day 2, 5, and 6 in experiment 1.
