Abstract
Strains of human-derived bacteria have been obtained from complex fecal samples and shown to induce accumulation of Th17 cells in the intestine and promote immune functions. Pharmaceutical compositions containing these bacteria can be used as anti-infectives and as adjuvants in mucosal vaccines.
