A bacterial signaling molecule can alter the composition of the gut microbiome in mice, according to the results of a study published today (March 19) in Cell Reports. Researchers from the Instituto Gulbenkian de Ciencia (IGC) in Oeiras, Portugal, have shown that boosting the levels of a quorum-sensing molecule in the intestines of mice treated with a gut microbe-depleting antibiotic results in the repopulation of beneficial bacterial species.
