Abstract

Probiotic treatments are thought to increase the levels of commensal bacterial species that populate the human gut, causing no harm to their host and playing an important role in maintaining gut health. This study is an investigation of the effect of a probiotic treatment on the level of a known commensal bacterium in the guts of healthy human subjects, which was significantly increased with probiotic treatment compared with a control. The authors concluded that the probiotic may thus help to promote gut health.
