The presence of Ureaplasma species were prevalent in the placentae of women delivering moderate/late preterm and was associated with histological chorioamnionitis. This according to a study in which women delivering moderate/late preterm (n=477) and their infants/placentae (n=535) were recruited and swabs of chorioamnion tissue, chorioamnion tissue and cord blood were obtained at delivery and analyzed. Researchers found:
• Microorganisms were detected in 10.6% of all placentae, delivered late preterm (n=443) and at term (n=92).
• Significantly, Ureaplasma spp. were the most prevalent microorganisms detected and their presence was associated with histological chorioamnionitis in moderate/late preterm and term placentae.
• The presence of ureaplasmas within the chorioamnion was also associated with elevated levels of granulocyte colony-stimulating factor.
