Many diseases related to bacteria, such as inflammatory bowel disease or colorectal cancer, are associated with an overgrowth of gut bacteria considered 'bad'. However, a study published in the journal Cell suggests that changes in microbial load, rather than the disease itself, could be the driving factor behind the presence of these harmful species associated with pathologies.

Two studies published in the journal Nature Communications have found specific characteristics in the microbiota of people with depression, including populations of different ethnicities and habits.
