Day pertains to experimental time points corresponding to the indicated bird ages. PBS: birds were gavaged with sterile 1× phosphate-buffered saline. Cc and Cj preceding the strain number indicate C. coli and C. jejuni, respectively.
One room housed the control birds (gavaged with PBS) and three rooms housed the turkeys dual inoculated with Campylobacter spp.
