Summary

The investigators have two hypotheses: (1) The probiotic L. rhamnosus HN001, when compared to placebo, will reduce S. aureus nasal colonization when taken for four weeks. (2) The probiotic L. rhamnosus HN001, when compared to placebo, will reduce S. aureus gastrointestinal colonization when taken for four weeks.
