Comparative evaluation of fermented ginseng on alleviating antibiotic-associated diarrhea in mice

Antibiotic associated diarrhea (AAD) was a common side effect of antibiotics, and fermented ginseng exhibited potential in treating AAD. In this study, the effects of fermented red, white, and black ginseng on AAD were investigated, with a focus on intestinal flora and inflammation. Clindamycin was used to induce AAD in mice, which caused severe diarrhea and weight loss. However, treatment with fermented ginseng effectively alleviated diarrhea, and reduced inflammation in colonic serosal tissue, thereby mitigating antibiotic-induced intestinal tissue damage. 16S rRNA sequencing revealed that clindamycin disrupted the Bacteroides/Firmicutes ratio (P < 0.001), which was reversed by fermented ginseng treatment. Furthermore, inflammatory cytokines like IL-1β, IL-6, and TNF-α significantly decreased (P < 0.05) after clindamycin treatment but returned to normal levels following fermented ginseng treatment. In conclusion, fermented red, white, or black ginseng (at a dosage of 0.5 g/kg) exhibited efficacy against AAD in mice, reinstating gut flora balance and easing inflammation.
