Aggression shapes the gut microbiome; a study in rats.

ABSTRACT: The gut-brain axis is regarded as a bidirectional communication system that integrates signals from the gut microbiome into behavioral aspects and vice versa. The aim of the present study was to investigate the gut microbiome-behavior interaction in relation to aggression. For that, male rats from a group-housed colony were individually housed with a female to become territorial. Next, a coping strategy was assigned to them, by evaluating their aggression levels against an intruder, during the Resident-Intruder test (RI). To investigate if their microbiome would change as a consequence of the developed coping strategy, fecal samples were collected before and after the RI test. We found that the relative abundances of Ruminococcaceae UCG-5 and Gram-negative bacterium cTPY-13 in rats sampled
