Not only did microbes diversify within early modern human hosts as they traveled and settled in different geographical locations, they also followed human evolution by limiting themselves to the gut.
Researchers reveal significant differences in gut bacteria in patients with multiple sclerosis compared to those without the autoimmune disease. The study also uncovered novel mechanisms by which the bacteria may influence the disease.
Early life exposure to antibiotics has a long-lasting effect on the enteric nervous system, microbiome, and gut function.
Stool samples taken from Viking latrines allowed researchers to map the genome of the Whipworm parasite. The study maps the parasite's global spread and relationship with human beings.
Exposure to air pollution within the first 6 months of life alters a child's microbiome, increasing the risk for allergies, diabetes, obesity, and influencing brain development.
Western diets high in sugars reduce the number of Th17 inflammatory cells in the guts of mice, setting off a chain of events that lead to metabolic diseases, prediabetes, and obesity.
Students who reported recent suicidal thoughts had different bacterial compositions in their saliva compared to those who did not report suicidal thoughts. Significantly, suicidal students presented with lower levels of Alloprevotella rava, a bacteria associated with positive brain health, in their saliva samples.
Researchers developed polymeric micelles of butyrate, a bacterial compound made by healthy a microbiome, that is effective against peanut allergies in mice.
Researchers identified a pathway that begins in the gut and ends with a pro-inflammatory protein in the brain that appears to contribute to the development and progression of Alzheimer's disease.
Opioids impact the gut microbiome of developing fetuses, altering metabolic pathways and increasing the risks of both neurological and behavioral differences later in life.
