Abstract:
This study was aimed to explore the effect of Zingiberis Rhizoma extract on rats with antibiotic-associated diarrhea(AAD), and reveal the modulation of gut microbiota during alleviation of AAD. AAD rat model was successfully established by exposing rats to appropriate antibiotic mixed solution. Peficon(70 mg·kg~(-1)·d~(-1)) was used as positive control, then rats were treated with 200 mg·kg~(-1)·d~(-1) and 400 mg·kg~(-1)·d~(-1) of Zingiberis Rhizoma extract for low and high dosage groups of Zingiberis Rhizoma extract, respectively. The weight changes of the rats were observed, and the degree of diarrhea were evaluated by fecal score, 120 min fecal weight and fecal water content. Colon tissues for histopathological examination were stained with hematoxylin and eosin(HE), and 16 S rRNA sequencing analysis of gut microbiota was performed. The results showed that compared with the model group, the degree of diarrhea, indicated by fecal water content, fecal score, and 120 min fecal weight of positive control group, Zingiberis Rhizoma low-dose group and Zingiberis Rhizoma high-dose group were significantly ameliorated. And the treatment of Zingiberis Rhizoma could significantly improve the pathological condition of colon tissue in AAD rats, especially the high dose of Zingiberis Rhizoma. In addition, 16 S rRNA sequencing analysis of gut microbiota showed that the diversity and abundance of gut microbiota were significantly improved and the reco-very of gut microbiota was accelerated after given high-dose of Zingiberis Rhizoma, while no significant changes of alterations were observed after given Pefikon. Of note, compared with the pefikon group, the abundance and diversity of gut microbiota in Zingi-beris Rhizoma high-dose group were significantly elevated. At the phylum level, the abundance of Firmicutes in AAD rats increased and the abundance of Proteobacteria was decreased after the Zingiberis Rhizoma intervention. At the genus level, the abundance of Bacillus spp., Lachnoclostridium and Escherichia coli-Shigella were decreased, and the abundance of Lactobacillus spp., Trichophyton spp., and Trichophyton spp., etc., were increased. While compared with the AAD model group, there was no significant difference of gut microbiota after given Peficon. The results showed that Zingiberis Rhizoma exerted beneficial health effects against AAD, and positively affected the microbial environment in the gut of rats with AAD.
