3.1 Bacterial 16S rRNA sequence data
A
total of 335455 raw reads were yielded from 8 samples.
After
quality filtering,
299149
valid reads were obtained, with an average of 37393 valid reads per
sample remaining. All estimated Coverage values were over 99%, which
indicated the current sequences sufficiently covered the diversity of
the sample of bacterial communities (Table 1). Retained 268 OTUs,
clustered at 97% sequence similarity, were detected in samples. Among
them, 155 OTUs were shared between both sexes, 110 OTUs were specific in
male, whereas only three OTUs were specific in female.
