Popis: Abstract Introduction Gut microbiota manipulation may be a potential therapeutic target to reduce host energy storage. There is limited information about the effects of probiotics/synbiotics on intestinal microbiota composition in children and adolescents with obesity. The objective of this randomized double-blind placebo-controlled trial was to test the effects of a multispecies synbiotic on intestinal microbiota composition in children and adolescents with exogenous obesity. Method Children with exogenous obesity were managed with a standard diet and increased physical activity and were randomly allocated into two groups at a ratio of 1:1; the 1st group received synbiotic supplementation (probiotic mixture including Lactobacillus acidophilus, Lacticaseibacillus. rhamnosus, Bifidobacterium bifidum, Bifidobacterium longum, Enterococcus faecium (total 2.5 × 109 CFU/sachet) and fructo-oligosaccharides (FOS; 625 mg/sachet) for 12 weeks; the 2nd group received placebo once daily for 12 weeks. Fecal samples were obtained before and at the end of the 12-week intervention to characterize the changes in the gut microbiota composition. Detailed metagenomic and bioinformatics analyses were performed. Results Before the intervention, there were no significant differences in alpha diversity indicators between the synbiotic and placebo groups. After 12 weeks of intervention, the observed taxonomic units and Chao 1 were lower in the synbiotic group than at baseline (p
