intestinal microbiota during transplant hospitalization. Blautia abundance is depicted by a solid black line with 95% confidence bands shown in gray constructed using moving average filtering. B) Daily nutritional and microbiota analysis was collected in 5 allo BMT patients during transplant hospitalization, and abundance of Blautia analyzed for stool samples stratified by kCal consumption. C) Stool abundance of Clostridials (the order to which Blautia belongs) was assayed in mice before and after one week of 25% reduction m food consumption.
