Premature delivery is still a significant problem in Obstetrics. It has multiple causes, with around 50% thought due to infection. Of note infection as a pathogenesis is more likely in those pre-term births occurring <30 weeks gestation and is largely sub-clinical. Potential pathogens largely arise from the ascending route and from the endogenous vaginal flora, causing chorioamnionitis. Resultant morbidity from the release of endo+/exotoxins from such pathogens, the stimulation and production of inflammatory cytokine pathways, prostaglandins, metalloproteinases includes maternal sepsis (chorioamnionitis, septicaemia, post-partum endometritis), pre-term delivery (infant pre-maturity and its consequences, increased susceptibility to cerebral palsy and neonatal sepsis). As well, infection increases mortality due to fetal loss (extreme pre-maturity) as well as severe neonatal sepsis.

The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
