Microbiota from alginate oligosaccharide-dosed mice successfully mitigated small intestinal mucositis [PDF]

Microbiome, 2020
AbstractBackgroundThe increasing incidence of cancer and intestinal mucositis induced by chemotherapeutics are causing worldwide concern. Many approaches such as fecal microbiota transplantation (FMT) have been used to minimize mucositis. However, it is still unknown whether FMT from a donor with beneficial gut microbiota results in more effective ...
