- athe numbers of OTUs and Chao1 indexes of infant group had statistical significance (P < 0.05) with both young, middle and senile groups. No significant difference was found between young, middle and senile groups.
- bShannon entropy index of infant group had statistical significance (P < 0.05) with middle and senile group, but no significant difference were found between young, middle and senile groups
