The metagenome of the female upper reproductive tract.

ABSTRACT:

Background

The human uterus is traditionally believed to be sterile, while the vaginal microbiota plays an important role in fending off pathogens. Emerging evidence demonstrates the presence of bacteria beyond the vagina. However, a microbiome-wide metagenomic analysis characterizing the diverse microbial communities has been lacking.

Results

We performed shotgun-sequencing of 52 samples from the cervical canal and the peritoneal fluid of Chinese women of reproductive age using the Illumina platform. Direct annotation of sequencing reads identified the taxonomy of bacteria, archaea, fungi and viruses, confirming and extending the results from our previous study. We replicated our previous findings in another 24 samples from the vagina, the cervical canal, the uterus and the
