What infection causes chorioamnionitis?

Answer 1

"Chorioamnionitis is an infection of the membranes (placental tissues) and amniotic fluid. It occurs in about 1 to 2 percent of all pregnancies, but is much more common in preterm births. Chorioamnionitis can cause bacteremia (blood infection) in the mother and may lead to preterm birth and serious infection in the newborn baby. Other terms for chorioamnionitis include intra-amniotic infection and amnionitis. The organisms usually responsible for chorioamnionitis are those that are normally present in the vagina, including Escherichia coli (E. coli). Group B streptococcus may also cause the infection. Chorioamnionitis can develop when the membranes (amniotic sac) are ruptured (broken) for an extended period. This allows the vaginal organisms to move upward into the uterus."
