Blautia abundance

1. Multidomain lifestyle intervention increases Blautia abundance in humans (p = 0.0132).

   “Microbiota profiling revealed a significant increase of the Blautia genus in the intervention group (IV6, intervention after 6 months) when compared to the control group (C6, control after 6 months) ( p = 0.0132)”

1. Blautia abundance is associated with depression in humans (r = -0.4120, p = 0.0022).

   “The Blautia genus abundance was negatively correlated with depression ( r = ‐0.4120, p = 0.0022) and loneliness scores ( r = ‐0.3328, p = 0.0184)”
