The Role of <i>Ureaplasma</i> Species in Prenatal and Postnatal Morbidity of Preterm Infants: Current Concepts

Ureaplasma species are considered commensals of the adult urogenital tract. Yet, in pregnancy, Ureaplasma parvum and Ureaplasma urealyticum have been associated with chorioamnionitis and preterm birth. In preterm infants, Ureaplasma respiratory tract colonization has been correlated with the development of bronchopulmonary dysplasia and has been implicated in the pathogenesis of other complications of prematurity. Controversies on the impact of Ureaplasma exposure on neonatal morbidity, however, remain, and recommendations for screening practices and therapeutic management in preterm infants are missing.
