Background: The early colonization and establishment of the microbiome in newborns is a crucial step in the development of the immune system and host metabolism. However, the exact timing of initial microbial colonization remains a subject of ongoing debate. While numerous studies have attempted to determine the presence or absence of intrauterine bacteria, the majority of them have drawn conclusions based on sequencing data from maternal or infant samples taken at a single time point.

Intrauterine growth restriction (IUGR) caused by placental dysfunctions leads to fetal growth defects. Maternal microbiome and its metabolites have been reported to promote placental development. Milk fat globule membrane (MFGM) is known for its diverse bioactive functions, while the effects of gestational MFGM supplementation on the maternal gut microbiota, placental efficiency, and fetal development remained unclear.

Indwelling intrauterine contraceptive devices (IUDs) have surfaces that facilitate the attachment of spp., creating a suitable environment for biofilm formation. Due to this, vulvovaginal candidiasis (VVC) is frequently linked to IUD usage, necessitating the prompt removal of these devices for effective treatment.

Recent evidence challenging the notion of a sterile intrauterine environment has sparked research into the origins and effects of fetal microbiota on immunity development during gestation. Rhesus macaques (RMs) serve as valuable nonhuman primate models due to their similarities to humans in development, placental structure, and immune response. In this study, metagenomic analysis was applied to the placenta, umbilical cord, spleen, gastrointestinal tissues of an unborn RM fetus, and the maternal intestine, revealing the diversity and functionality of microbes in these tissues.

The aim of this study is to present a panel that includes the main bacterial genera associated with endometritis. We conducted a search using the terms "endometritis women" OR "female endometritis" OR "pelvic inflammatory disease" AND bacteria* OR "uterine microbiome" in two databases: PubMed and Web of Science, without language or publication year restrictions. The panel is based on an analysis of 40 studies published over the past 38 years.
