Research groups from Instituto Gulbenkian de Ciência (IGC) that study evolution, immunity and microbiology unveiled two new mechanisms in the microbiota: in older populations, the bacterium E. coli evolves in a way that can become potentially pathogenic and increase the risk of disease and, according to data obtained in another study, the metabolism of the same bacterium present in the microbiota differs if it is alone or accompanied by other bacteria. The discoveries are available in the latest edition of Current Biology.
