Myometrial Biopsy for the Detection of Infection

The infection is a dynamic process probably beginning shortly after the onset of labor. This
process continues and is enhanced during active uterine contractions, which result in
bacteria from the vagina being drawn up into the uterine cavity. During labor, bacterial
colonization of the amniotic fluid, the decidua, and even the fetus can occur, resulting in
infection of the mother and the fetus.
