The authors investigated the relationship between histologically confirmed chorioamnionitis and the development of adnatal infection in the neonate. From a total of 4,144 deliveries during the investigation period-January 1, 1988 to December 31, 1989-252 placentas of neonates after pathological deliveries were examined. Chorioamnionitis was recorded in 28.6%, i.e. in 72 placentas inflammatory changes were found. Adnatal infections of neonates with chorioamnionitis were detected in 20.8%, i.e. 15 neonates. On the other hand, in the group of neonates where no inflammatory changes of the placenta were present adnatal infections were recorded in 8 infants, i.e. 4.4% (p = 0.00004). The mortality rate from adnatal infections in the group of neonates with chorioamnionitis was 4.16%. In the group of neonates without chorioamnionitis no death due to adnatal infection was recorded (p = 0.00000). Chorioamnionitis is thus associated with a significantly higher incidence of clinical adnatal infection in neonates and mortality due to this infection.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
