Abstract：Abstract] AIM:To explore the dominant salivary microbiota in healthy children of Bonan ethnic group of Gansu province.METHODS:16S rRNA clone library was constructed to analyze the sequencing results.The analysis of diversity of bacterial community structure was conducted by BLAST,Mothur and Clustalx2.0.Phylogenetic tree was constructed.RESULTS:84 operational takonomic units(OTUs)were detected which belonged to 5 phyla,12 classes, 15 orders,18 families and 19 genera.Firmicutes was the most prominent (88.60%)species.6 genera were at high a-bundance (detection rate >1%):Streptococcus (70.28%),GranuIicatella (6.20%),Gemella(3.10%),Veillonel-la(1.81%),Neisseria(1.03%)and Haemophilus(1.03%).Streptococcus was detected in all 8 samples.CONCLU-SION:The salivary microbial community structure of healthy children of Bonan ethnic group is abundant.Streptococcus is the dominant bacteria.
