Introduction
Overview
Overview
Causes
Causes
Chorioamnionitis may be caused by either bacterial, fungal, or viral microorganisms.[1]
Common Causes
Common bacterial causes of chorioamnionitis include:[1][2]
- Bacteroides sp., especially Prevotella bivius
- Streptococcus agalactiae
- Enterobacteriaceae
- Gardnerella vaginalis
- Mycoplasma pneumoniae
- Chlamydia trachomatis
- Ureaplasma urealyticum
- Fusobacteria sp.
- Escherichia coli
- Viruses (adenoviruses might be associated with histological inflammation.
- Fungi, especially candida, might be the causative agent of chorioamnionitis especially in women who become pregnant while using intrauterine devices.[2]
- Chorioamnionitis due to candida infection is associated by preterm birth and adverse fetal outcomes.[1]
- Trichomonas vaginalis might be the causative microorganism in chorioamnionitis, particularly in young and sexually active patients.
Common causative pathogens could be further divided based on the clinical outcome
- Certain microorganisms which might be seen in patients with spontaneous preterm labor (intact membranes):
- Fusobacterium nucleatum
- Sneathia sanguinegens
- Ureaplasma urealyticum
- Streptococcus mitis
- Gardnerella vaginalis
- Peptostreptococcus
- Leptotrichia amnionii
- Mycoplasma hominis
- Streptococcus agalactiae
- Lactobacillus species
- Bacillus species
- Coagulase-negative Staphylococcus species
- Prevotella species
- Delftia acidovorans
- Neisseria cinerea
