Pregnant women who later got preeclampsia had more of several specific bacteria types (Methanosaeta, Desulfomicrobium, Enterococcus, Mycobacterium, Thiobacillus, and Ochrobactrum) in their mouths compared to women who stayed healthy.

Scientific Claim

Women who developed preeclampsia had higher abundances of Methanosaeta, Desulfomicrobium, Enterococcus, Mycobacterium, Thiobacillus, and Ochrobactrum in their oral microbiota compared to normotensive pregnant women.

Original Statement

“The women who developed preeclampsia had higher abundances of Methanosaeta, Desulfomicrobium, Enterococcus, Mycobacterium, Thiobacillus, and Ochrobactrum. Normotensive pregnant women had higher abundances of Roseomonas, Johnsonella, Caulobacter and the nitrate-reducing genera Prevotella and Veillonella.”
