Official title
Bismuth Subsalicylate's Role in the Prevention of Travelers' Diarrhea and Impact on Acquisition of Gut Antimicrobial Resistance Genes
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine if the use of prophylactic bismuth subsalicylate (BSS) has an effect on the acquisition of travelers' diarrhea (TD) or antimicrobial resistance (AMR) genes in fecal samples among international travelers who departed from the United States to South East Asia, South Central Asia, or Africa. Our hypotheses will be tested using a double-blinded, placebo controlled randomized clinical trial with participants from a pre-travel health clinic in the United States.
