Mycobacterium vaccae

Urban Farm DB summary

A Wikipedia article on Mycobacterium vaccae, a non-pathogenic soil bacterium first cultured from cattle dung and also isolated from soil in Lang'o District, Uganda. It cites research in which heat-killed bacteria injected into mice raised serotonin levels and lowered anxiety, and live bacteria led mice to navigate a maze twice as fast with less anxious behavior. It also notes a meta-analysis of 54 clinical trials finding improved sputum conversion and radiological outcomes in tuberculosis treatment, and a 2019 study finding a lipid from the bacterium blocks several pro-inflammatory pathways in immune cells.
