U urealyticum was recovered from 6% and bacteria from 47%; 47% of placentas had no bacteria detectable. The presence of U urealyticum in placental parenchyma before 28 weeks is associated with increased risk of preterm labor and delivery, higher risk of fetal and maternal inflammation, and increased risk of intraventricular hemorrhage and echolucent brain lesions but not of early neonatal death.
