 Vaginal microflora dysbiosis in various pregnancy complications.

Pregnancy complicationsVaginal microflora dysbiosisReferences
MiscarriageLow abundance of Lactobacillus but elevation in L. iners, high levels of B. plebeius, G. vaginalis, M. girerdii, and increased diversity of CST-IV[5457]
Recurrent miscarriageDecreased abundance of Lactobacillus, high abundance of Prevotella, Gardnerella, Pseudomonas, family Ruminococcaceae, Anaerococcus[5860]
Preterm birthLow abundance of Lactobacillus, high abundance of G. vaginalis, increased diversity of CST-IV with L. iners dominance, high levels of S. amnii, Prevotella, Atopobium vaginane, Megasphaera[6164]
Gestational diabetesHigher abundance of Bacteroidetes, Veillonella, Klebsiella, Escherichia-Shigella, Enterobacter, Enterococcus, high levels of fungal flora like Candida and Saccharomyces[65, 66]
Preterm premature rupture of membraneL. iners, U. parvum, P. bivia, P. timonensis, G. vaginalis positively associated[67]
PreeclampsiaHigh abundance of Prevotella bivia[68]
