In rats prone to high blood pressure, the types and amounts of bacteria in the mouth are affected by the rat's genetic makeup.
The amount of sodium stored in the skin is linked to blood pressure levels in both humans and animals.
Cyanobacteria on the skin might help regulate sodium levels and blood pressure through special transporters that move sodium and chloride.
Bacteria in the mouth that convert nitrate to nitric oxide (like Actinobacteria) might help lower blood pressure by relaxing blood vessels.
In rats with different genetic modifications that affect blood pressure, the connection between gut bacteria and blood pressure isn't consistent - sometimes more of certain bacteria is linked to lower blood pressure, sometimes not.
In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria in the gut differ between these strains.
In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria on the skin differ between these strains.
In rats with different genetic modifications that affect blood pressure, the types and amounts of bacteria in the mouth differ between these strains.
In female rats, a specific part of the genome (RNO5) is linked to the amount of Cyanobacteria bacteria on the skin, and this is connected to blood pressure levels.
In rats, a specific part of the genome (RNO10) controls the amount of Actinobacteria bacteria in the mouth, and this is linked to blood pressure levels.
In rats, the bacteria in the gut are different from those in the mouth and on the skin, with Bacteroidetes and Firmicutes being the most common types in the gut.
In rats, the bacteria on the skin are different from those in the mouth and gut, with Cyanobacteria being the most common type on the skin.
In rats, the bacteria in the mouth are different from those on the skin and in the gut, with Actinobacteria and Proteobacteria being the most common types in the mouth.
In rats, the types and amounts of bacteria on the skin differ between males and females, but this difference isn't seen in the mouth or gut bacteria.
In rats prone to high blood pressure, the amount of Cyanobacteria bacteria on the skin is linked to blood pressure levels, but this connection is different for male and female rats.
In rats that are prone to high blood pressure, having more of a certain type of bacteria (Actinobacteria) in the mouth is linked to lower blood pressure.
In pregnant women, the amount of Veillonella dispar bacteria in the mouth wasn't linked to systolic blood pressure, but showed a similar pattern to diastolic blood pressure that wasn't quite statistically significant.
In pregnant women, the amount of Prevotella bacteria in the mouth wasn't linked to blood pressure levels.
The types and amounts of bacteria in the mouths of pregnant women who later got preeclampsia were more varied between individuals compared to women who stayed healthy.
Pregnant women who later got preeclampsia ate about the same amount of nitrate-rich vegetables (like spinach and beets) as women who stayed healthy during pregnancy.
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.
In pregnant women, higher levels of Veillonella bacteria in the mouth were linked to higher levels of Prevotella bacteria.
The amount of a specific gene involved in nitrate reduction (narH) was similar in the mouths of pregnant women who later got preeclampsia and those who stayed healthy.
In pregnant women, higher levels of Veillonella parvula bacteria in the mouth were linked to lower diastolic blood pressure, and showed a similar but less strong pattern for systolic blood pressure.
