Vaginal colonization with  Ureaplasma  ( U. ) spp. has been shown to be associated with adverse pregnancy outcome; however, data on neonatal outcome are scarce. The aim of the study was to investigate whether maternal vaginal colonization with  U.  spp. in early pregnancy represents a risk factor for adverse short- or long-term outcome of preterm infants. Previously, 4330 pregnant women were enrolled in an observational multicenter study, analyzing the association between vaginal  U.  spp. colonization and spontaneous preterm birth.  U.  spp. colonization was diagnosed via PCR analysis from vaginal swabs. For this study, data on short-term outcome were collected from medical records and long-term outcome was examined via Bayley Scales of Infant Development at 24 months adjusted age. Two-hundred-and-thirty-eight children were born <33 weeks gestational age. After exclusion due to asphyxia, malformations, and lost-to-follow-up, data on short-term and long-term outcome were available from 222 and 92 infants, respectively. Results show a significant association between vaginal  U.  spp. colonization and severe intraventricular hemorrhage (10.4% vs. 2.6%,  p  = 0.03), retinopathy of prematurity (21.7% vs. 10.3%,  p  = 0.03), and adverse psychomotor outcome (24.3% vs. 1.8%, OR 13.154, 95%CI 1.6,110.2,  p  = 0.005). The data suggest an association between vaginal  U.  spp. colonization in early pregnancy and adverse short- and long-term outcome of very preterm infants.
