The Effect of Bifidobacterium Probiotics on Gut Microbiota Changes in Healthy Adults During Short-term Travel Along the Silk Road
Sponsor: Universiti Sains Malaysia
Summary
Journeying along the historic Silk Road exposes travelers to dramatic dietary shifts, unfamiliar microbial environments, and the physical stresses of long-distance travel-all known to disrupt gut health and cause gastrointestinal complaints, including traveler's diarrhea and sleep disturbances. Such disruptions may also elevate the risk of acquiring antibiotic-resistant organisms. This randomized, double-blind, placebo-controlled trial evaluated whether probiotic supplementation can help maintain gut microbial balance and support traveler well-being during trips to Silk Road regions. In addition to monitoring changes in gut microbiota composition, the study assessed gastrointestinal symptoms, sleep quality, anxiety levels, overall well-being, gut immune markers, functional profiles of the microbiome, and the presence of antibiotic resistance genes.
