Jos Bosch, an associate professor of psychology at the University of Amsterdam and Robert Kraaij, an assistant professor at Erasmus University Medical Center in Rotterdam conducted studies of over 3,000 adults and their gut microbiome.

Their study found higher levels of two strains of gut bacteria, Lachnospiraceae and the genus Eggerthella, which were associated with more depressive symptoms, according to a December 06 2022 Wall Street Journal report. On the other hand, Ruminococcaceae were significantly reduced in depressive participants (1).

This confirms Oxford Health Group Dr. Najaf Amin’s research who found that Eggerthella, Hungatella, Sellimonas, and Lachnoclostridium are more abundant among people suffering from depression. He also found that Coprococcus, Lachnospiraceae, Ruminococcusgauvreauii, Eubacterium ventriosum, Subdoligranulum, Ruminococcaceae, we’re deficient among those suffering from depression, according to Amin as reported by Dr. Paul Ian Cross, December 12 2022 in Medical News Today (2).

These results point toward the possibility of developing gut bacterial based remedies for treating depression, though further research is required.
