Dietinduced extinction in the gut microbiota compounds over. Changes in hostmicrobiota interactions over evolutionary time. First, 58 of the 208 highconfidence otus that exhibit dietinduced decline in abundance recovered were no longer at least twofold less abundant with the reintroduction of macs illustrating microbiota resilience over short time scales. The ancestral and industrialized gut microbiota and implications for. This breeding strategy was repeated for four generations. Mice from the previous experiment consuming the lowmac diet or the high. In mice on a low microbiotaaccessible carbohydrate mac diet, the diversity of the gut microbiota is depleted, and the effect is transferred and compounded over generations. Dietinduced extinctions in the gut microbiota compound over generations. Sepsis, infectioninduced organ dysfunction, affects approximately 1.
The gut is home to trillions of microorganisms that have fundamental roles in many aspects of human biology, including immune function and metabolism1,2. We hypothesized that dietinduced microbiota diversity loss would be magnified over generations. While diet can induce a shift in the gut microbiota, these changes. Diet can also influence infection via the gut microbiota beyond sepsis. Dietinduced extinctions in the gut microbiota compound over. Over the past decade of studying the gut microbiome. However, over several generations, a lowmac diet results in a progressive loss of diversity, which is not recoverable after the reintroduction of dietary macs. Mice from the previous experiment consuming the lowmac diet or the highmac diet were used to generate a litter of pups. Dietinduced extinction in the gut microbiota compounds over generations. Dietmicrobiota interactions and personalized nutrition weizmann. Here we show that changes in the microbiota of mice consuming a lowmac diet and harbouring a human microbiota are largely reversible within a single generation. Macs over multiple generations caused the apparent extinction of some members of the gut microbiota 5.
