Here we collected the urine samples from 147 Chinese women of reproductive age, and explored the nature of colonization by 16S rRNA gene amplicon sequencing, real-time qPCR and live bacteria culture.
Our data showed distinct bacterial communities in urine, indicative of a non-sterile environment. Types of diverse (56.93%), Streptococcus-dominated (22.63%), and Lactobacillus-dominated (13.87%) were the three most common types in the cohort. Potential relevance of the microbiota between the urine and reproductive tract were also identified.
