Abstract:Mount Emei (EM) and Mount Huangshan (HS) are both famous for its Macaca thibetana ecotourism in China. The comparative study on the composition of gut microbiome in M. thibetana between the two places will improve our understanding on the effects of habitats and tourism managements on wild primates. In this study, the 16S rRNA gene was used as molecular marker to sequence the gut microbiome of the M. t. thibetana in Mount Emei, and compared with the community structure of the gut microbial of the Mount Huangshan M. t. huangshanensis. The result shows that a large number of OTUs were shared by the gut microbita of M. thibetana from EM and HS, however they were significantly different in community composition and microbial diversity. The dominant phylum microbial communities in EM were from Firmicutes (69.04%±11.81%), Bacteroidetes (21.59%±10.05%) and Actinobacteria (2.735±2.17%). Whereas they were Firmicutes (46.34%±8.15%), Bacteroidetes (36.75%±6.38%) and Proteobacteria (14.915±8.06%) in HS. With regard to the highest abundant genus, it was Oscillospira (23.49%±16.63%) in EM, and Prevotella (36.35%±9.15%) in HS. In terms of the community diversity, the alpha diversity index in HS was significantly lower than EM, and their microbial community structure also had significant differentiation. PICRUSt analysis revealed that EM enhanced in KEGG pathways such as lipid metabolism and Xenobiotics biodegradation and metabolism. In contrast, HS enhanced in Glycan biosynthesis and metabolism, etc. In addition, several infectious pathogenic bacteria were found in gut of EM, which probably is related to the ecotourism in Mount Emei.
