Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. One of the most common indications for probiotic treatment is the prevention of antibiotic-associated diarrhea (AAD). Unfortunately, many probiotic products used for AAD are not supported by rigorous independent research, and often results in non-evidence-based usage. Our research group has worked closely with the Federal Drug Administration (FDA) to move research forward for the most well studied Bifidobacterium strain. To explore possible mechanisms, we will also study the gut microbiota composition and function by collecting five fecal samples at multiple time points from all participants. The microbiota includes hundreds of species, and its disruption is hypothesized to be an important factor in the development of AAD.
