Chorioamnionitis Inflammation accompanies<unk>  and is likely to complicate treatment and recovery. Inflammation is linked to reduced growth of the lungs of the premature baby. Pathogenesis The recent identification of the presence of microorganisms in maternal-infant body fluids that were previously thought to be sterile has provided one explanation for the presence of the inflammatory response in both the mother and infant. Sixty-one percent of pregnant women with chorioamnionitis, or inflammation of the amniotic fluid, were found to be infected by microorganisms. Often, more than one pathogen was present. In fifteen percent of pregnant women inflammation was still evident even though there was no evidence of pathogens. This may indicate that there are other causes. A high percentage, 51% to 62%, of pregnant women who had chorioamnionitis also had inflammation of the placenta.
