All results represent statistically significant changes (P < 0.05) in the positive control (E. coli-challenged group) relative to the negative control (non-challenged group), except for those marked with a hash (#),
which indicate a statistical tendency (P < 0.10). RA: Relative abundance; E. coli: Escherichia coli; BW: body weight; NA: not available.
