Which two pathogens are most commonly associated with chorioamnionitis?

• A. Listeria and E. coli
• B. Ureaplasma and Mycoplasma
• C. Streptococcus and Staphylococcus
• D. Chlamydia and Gonorrhea

Answer: (B)

Chorioamnionitis, an infection of the fetal membranes, is most commonly associated with pathogens that are part of the normal flora or that can invade the amniotic fluid environment. Ureaplasma and Mycoplasma are two such pathogens that have been implicated in this condition due to their ability to thrive in the urogenital tract and ascend into the amniotic cavity, leading to infection. These organisms are particularly notable for their small size and lack of a cell wall, which allows them to adapt to the unique conditions of the amniotic environment and evade some classical forms of immune response. Their presence can trigger inflammatory responses that may lead to chorioamnionitis, which is associated with risks such as preterm labor and complications for both the mother and the fetus. While other pathogens listed also play roles in infections during pregnancy, Ureaplasma and Mycoplasma are specifically recognized for their strong correlation with chorioamnionitis due to their prevalence and the types of infections they are known to cause in the pregnant population. Their association is particularly significant in cases where there are multiple risk factors for infection, such as prolonged rupture of membranes.
