Scientists found that bacteria in rats' mouths and skin help control blood pressure. Mouth bacteria make chemicals that relax blood vessels, while skin bacteria help manage salt levels.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.
Systematic Reviews & Meta-Analyses
Max 100Randomized Controlled Trials
Max 90Cohort Studies
Max 72Case-Control Studies
Max 58Cross-Sectional Studies
Max 44Case Reports & Case Series

Evidence Score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Bacteria in the mouth help regulate blood pressure by converting nitrate to nitrite, which is part of the body's natural blood pressure control system.
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, 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 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 gut are different from those in the mouth and on the skin, with Bacteroidetes and Firmicutes being the most common types in the gut.
