The researchers, who published their findings in the journal Nature Microbiology, collected feces samples from just over 1,000 people in a special project called the Flemish Gut Flora Project.

The analyzes show that many of the intestinal bacteria are positively or negatively linked to mental health.

For example, two of the bacteria Coprococcus and Dialists were consistently very rare in individuals with severe depression – whether or not they were treated with antidepressants.

Bacteria and Depression

Researchers point out that research circles have long debated a possible connection between intestinal bacteria and depression.

The subject is controversial – but most point to the fact that the connection is real. Many bacteria produce substances that are neuroactive, that is, substances that affect our nervous system and therefore our mental state.

Some microbes may, among other things, produce dopac, a chemical that is included in the neurotransmitter dopamine, which is linked to our reward system and thus to our well-being.

Catalog of intestinal bacteria

The researchers behind the study, led by microbiologist Jeroen Raes of the University of Leuven in Belgium, have analyzed the genome of more than 500 bacteria in the human gastrointestinal tract.

They have now made a catalog of the various microbes and the neuroactive substances they produce.

Some of the bacteria are apparently capable of producing a whole battery of substances with different neurological effects.
