Equine placental microbiome

Abstract

The mammalian placenta has long been regarded as a sterile organ that nourishes and protects the growing fetus during gestation. There is recent evidence in mares that the placenta harbors a unique microbiome. While this work is in its infancy in the horse, there is a growing amount of data in human literature to support the role of the placental microbiome in pregnancy success and adverse outcomes. The following paper will review and highlight this up and coming area of interest in equine reproduction.
