The Alabama Preterm Birth Study: Umbilical cord blood Ureaplasma urealyticum and Mycoplasma hominis cultures in very preterm newborn infants

U urealyticum and M hominis cord blood infections are far more common in spontaneous vs indicated preterm deliveries and are strongly associated with markers of acute placental inflammation. Positive cultures are associated with neonatal systemic inflammatory response syndrome and probably bronchopulmonary dysplasia.
