Perinatal outcomes according to maternal ESBL-E vaginal colonization
Finally, we compared the perinatal outcomes according to ESBL-E vaginal colonization in 1,460 mothers and 1,616 live-born neonates. As shown in Table 5, the gestational age at admission and delivery was significantly earlier, and the rates of abortion and histologic chorioamnionitis were significantly higher in the ESBL-E-positive group than in the ESBL-E-negative group. The overall rate of EONS (7.6% vs 2.5%,P = 0.040) and the rate of proven EONS were significantly higher in the ESBL-E-positive group than in the ESBL-E-negative group (6.0% vs 1.1%, P = 0.002).
