Commentary: Uterine Microbiota: Residents, Tourists, or Invaders?

Abstract

The recently published review by Baker et al. summarizes the current status of uterine microbiota with the aim to promote research priorities and discussion on this novel research field (1). The authors are to be congratulated on this much anticipated review as microbiota in the uterus is one increasing research area, though poorly investigated microbial niche relative to other organs. However, emerging evidence is beginning to indicate that the uterine microbiota has important implications for female (reproductive) health and disease, and it is becoming evident that the concept of sterile uterus is outworn, although the true core uterine microbiota still needs to be assessed.
