‘gut–brain axis’

Gut microbes linked to depression

Two species of gut bacteria — Dialister and Coprococcus — are reduced in people with depression, finds a large study of Belgian and Dutch people. Meanwhile, Faecalibacterium and Coprococcus bacteria were consistently associated with higher quality of life. The finding doesn’t prove cause and effect, but it does contribute to mounting evidence that there is a ‘gut–brain axis’ at work.
