Gut Microbiota - GoKawiil

Study ties gut bacterium B. uniformis and an odd-chain fatty acid to reduced atherosclerosis in mice

Researchers compared gut microbiota from people with and without disease and found several bacterial genera, including Bacteroides uniformis, enriched in healthy individuals. In mouse experiments, oral dosing with B. uniformis colonized the gut, reduced aortic plaque buildup measured by Oil Red O staining, and affected metabolic markers such as glucose tolerance tests and liver mass compared with controls.

Study finds gut microbes shared by Hadza and Tsimane trace ancient human migrations

Researchers led by Carter et al., writing in Nature, compared gut microbiota of Tanzania's Hadza people with Bolivia's Tsimane people, whose ancestors diverged tens of thousands of years ago. They found hundreds of microbial species common to both groups, with genetic differences between strains aligning with the timing of prehistoric human migrations. Many of these shared microbes are now rare or absent in people living in industrialized regions.
