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.

Scientific Claim

Skin microbiota shows sex-specific differences in diversity that are not observed in oral or gut microbiota in rats.

Original Statement

“Sex-specific differences in β-diversity were observed only in skin microbiota.”

From study:Beyond the Gastrointestinal Tract: Oral and Sex-Specific Skin Microbiota Are Associated with Hypertension in Rats with Genetic Disparities.

Assessment Explanation

The study describes observed differences in microbial diversity between sexes for different body sites. The phrase 'sex-specific differences...observed only in skin microbiota' accurately reflects the descriptive nature of the finding.

Similar Assertions

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 prone to high blood pressure, the types and amounts of bacteria on the skin are affected by the rat's genetic makeup, but this effect is different for male and female rats.
