aOnly genera that were present at ≥1% in a sample are included in this table.
bMice were administered 1 dose (108 CFU/mouse/day) daily of L. casei strains for 1 week and sacrificed 3.5h after the last dose.
cThe detection limit was 0.00009 and this value was used to calculate the p-value.
dGenera that differ from control within each group are shown in bold (p≤0.05). The statistical difference was examined using the Monte-Carlo test.
eThe number of genera that differed from the control for that treatment.
IS: Incertae Sedis.
BQL: Below quantifiable limit.
