The research group of JIA Huijue at Shenzhen’s BGI found that special microbiota exist in the reproductive system of healthy females which may be used as biomarkers for certain diseases. They analyzed the microorganisms in six regions of 110 healthy women of childbearing age and found that lactobacilli were abundantly present in the vagina and fornix, whereas in the upper regions these were replaced by Pseudomonas and other bacteria. Composition of microbiota changed with the menstrual cycle and were associated to illnesses such as endometriosis. The finding may lead to the identification of biomarkers for vaginal-uterine disorders, https://www.nature.com/articles/s41467-017-00901-0
