Causes of<unk>  stem from bacterial infection as well as obstetric and other related factors. Microorganisms Bacterial, viral, and even fungal infections can cause<unk> . Most commonly from Ureaplasma, Fusobacterium, and Streptococcus bacteria species. Less commonly, Gardnerella, Mycoplasma, and Bacteroides bacteria species. Sexually transmitted infections, chlamydia and gonorrhea, can cause development of the condition as well. Studies are continuing to identify other microorganism classes and species as infection sources. Obstetric and other Birthing-related events, lifestyle, and ethnic background have been linked to an increase in the risk of developing<unk>  apart from bacterial causation. Premature deliveries, ruptures of the amniotic sac membranes, prolonged labor, and primigravida childbirth are associated with this condition. At term mothers who experience a combination of pre-labor membrane ruptures and multiple invasive vaginal examinations, prolonged labor, or have meconium appear in the amniotic fluid are at higher risk than at term mothers experiencing just one of those events. In other studies, smoking, alcohol use and drug use are noted as risk factors. Those of African American ethnicity are noted to be at higher risk.
