Experimental studies performing fecal microbiota transplants (FMTs) from human to animals and between animals is providing enlightening information with regards to phenotypical characteristics that can potentially be influenced by the microbiome. A recent study by De Palma (1) has shown that fecal material from humans with irritable bowel syndrome (IBS) with diarrhea (IBS-D) invoked physical changes in the intestinal environment and in behavior. This is an interesting outcome, given the questions that have been raised about the relevance of certain models’ in light of the differences between the rodent gut physiology, the microbiome and the human condition (2,3).
