Global study finds gut bacteria swap genes at different rates, depending on living situation A new study that examined the microbiomes of people living around the world has found that gut bacteria continuously acquire new functionality—depending on host lifestyle and industrialization. The research centers around horizontal gene transfer (HGT), a process in which individual cells mix their genomes and acquire new functions from other microbes, which happens without having to reproduce or be inherited. According to Mathilde Poyet, PhD, co-author of the study, HGT ...

Thousands of different bacterial species live within the human gut. Most are beneficial, while others can be harmful. A new study from an MIT-led team has

International Study Reveals Higher Rates of Gene Transfer in the Industrialized Human Microbiome April 1, 2021 Global Microbiome Conservancy Co-founder Mathilde Poyet, PhD, collects lifestyle data from Bedik villagers in Senegal. [Global Microbiome Conservancy; Photo by F. Rondon] Share The composition of the gut microbiome is altered by many factors including, but not limited to, diet, exercise, and antibiotic use. Now, the first major paper from the Global Microbiome Conservancy (GMbC), a consortium that is collecting microbiome samples from underrepresented human populations around the wor...
