Maternal Ureaplasma Species Colonization and Neonatal Outcomes: A Large Cohort Study on Preterm Birth and Vertical Transmission

Maternal Ureaplasma colonization predisposes to preterm birth and neonatal morbidity. Vertical transmission varies by delivery mode and is the highest with extreme prematurity. Neonatal Ureaplasma colonization independently predicts severe acute morbidity, underscoring the need for targeted risk stratification and intervention in high-risk dyads.
