Data not sharing the same letter within a column are significantly different (P < 0.05). n: represents the numbers of studied samples.

*All bacteria results obtained by qPCR were expressed as mean of the log₁₀ value ± SE.

†Results were expressed as mean of the log₁₀ value ± SE of normalized data, calculated as the log number of targeted bacteria minus the log number of all bacteria.

‡Faecalibacterium prausnitzii is the major component of the Clostridium leptum group.
