Antibiotic-associated diarrhea (AAD) remains a significant clinical challenge, with current treatments often inadequate for fully restoring gut health. This study aimed to evaluate the effectiveness of synbiotics, including chitosan oligosaccharides, Bifidobacterium, Clostridium butyricum, and Lactiplantibacillus plantarum, in mitigating AAD in a canine model. Sixteen Beagle dogs were randomly assigned to an AAD model group or a synbiotic treatment group. Synbiotic supplementation significantly reduced diarrhea severity, improved intestinal morphology, and enhanced gut microbiota diversity. Furthermore, synbiotics upregulated the expression of tight junction proteins (ZO-1, occludin, claudin-1), thereby reducing mucosal permeability. A significant decrease in proinflammatory cytokines (IL-1β, TNF-α) further underscored the anti-inflammatory effects of the treatment. These findings suggest that synbiotics may offer a promising approach to restoring gut barrier integrity and modulating immune responses in cases of AAD. Further research is warranted to investigate the long-term impacts and underlying mechanisms of synbiotics in gut health restoration.

Prebiotic-probiotic synergy is vital to fermented milk's overall performance. This study investigates the effects of complex prebiotics (CPs) on the quality and functional properties of probiotic-fermented milk. Results indicated that CPs improved the physicochemical properties and sensory characteristics of fermented milk.

This study aimed to investigate the effects of infant formula supplements on level in the infant gut through a systematic review and network meta-analysis (NMA) of randomized controlled trials (RCTs).Systematic review included PubMed, EMBASE, MEDLINE, Scopus, Web of Science, and Cochrane CENTRAL to identify RCTs evaluating the effects of formulas supplemented with prebiotics, probiotics, synbiotics, β-palmitic acid, or combinations of β-palmitic acid with prebiotics on infant gut levels. A meta-analysis compared bifidogenic effects to standard formula.

Adolescence is characterized by an increased vulnerability to substance abuse, including alcohol consumption. We investigated the effects of a synbiotic intervention on disruptions of the microbiota-gut-brain axis induced by a drinking in the dark model of intermittent alcohol exposure in adolescent mice. We found that alcohol drinking induced specific shifts in gut microbiota, namely it increased Erysipelotrichaceae and reduced fecal butyric and isovaleric acids.

Background And Aim: Prediabetes is associated with metabolic disturbances that significantly increase the risk of developing cardiovascular disease (CVD). Probiotics and synbiotics may improve metabolic health, but their impact on CVD risk factors in prediabetic adults needs further evaluation. This meta-analysis evaluates the effects of probiotic and synbiotic supplementation on cardiovascular risk factors in individuals with prediabetes.

Background: Modulation of intestinal barrier, which function through zonulin pathway downregulation, represents a promising therapeutic strategy for chronic diseases. This systematic review aimed to evaluate the effects of prebiotic dietary fibers, probiotics, and synbiotics on intestinal permeability and immunity.
Methods: A systematic literature search of the EMBASE, PubMed, Web of Science, and Scopus electronic databases was conducted from database inception up to May 2024, supplemented by manual reference list searches.
