Apple Polyphenol Extract Suppresses Clostridioides difficile Infection in a Mouse Model.

ABSTRACT: Fruits such as apples are a dietary source of polyphenols and have health benefits. We studied the benefits of apple polyphenols in reducing intestinal infections. We explored the potential roles of apple polyphenols in combating Clostridioides difficile-induced intestinal infections by modulating the intestinal microbiota and metabolism in our study. Mice fed with apple polyphenols exhibited higher survival rates and improved diarrhea symptoms in a C. difficile infection mouse model given once-daily apple polyphenol extract (200 or 400 mg/kg bw) or phosphate-buffered saline. Feeding polyphenols enhanced anti-inflammatory effects and colon barrier integrity. In addition, apple polyphenols mitigated intestinal microbiota disorders in C. difficile infection, modulating the intestinal microbiota and increasing the abundance of beneficial microbiota. Apple polyphenols also improved fecal metabolic alterations in C. difficile-infected mice and modulated the expression of pathways related to intestinal inflammation. Our results suggest that apple polyphenol extract is a potential prebiotic agent that affects the intestinal microbiota and metabolism, thereby positively influencing intestinal infections.

Project description:Clostridioides difficile infection (CDI) is a common healthcare-associated infection and the leading cause of gastroenteritis-related deaths worldwide. To investigate the effects of peptide composition of different protein products on CDI, we analyzed and compared the peptide sequences and compositions from Engraulis japonicus and Glycine max using Ultra High Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS/MS). An animal model of CDI was also established to investigate the potential therapeutic effects of these peptides in vivo. The peptide compositions of E. japonicus and G. max differed, with only 11% of the peptide sequences being identical. Oral administration of the tested peptides could reduce intestinal inflammation, repair the intestinal barrier, increase the proportion of beneficial bacteria, and reduce the proportion of harmful bacteria, providing a therapeutic effect against CDI. However, the peptides may differ considerably in some aspects. E. japonicus peptides were superior to G. max peptides in promoting colon epithelial cell proliferation and repairing tight intestinal cell junctions. Interestingly, the two sources of peptides have different effects on the cecal microbiome. E. japonicus peptides can effectively restore the diversity and richness of intestinal microbiota, while G. max peptides have poor regulatory effects on the intestinal microbiota structure. Overall, E. japonicus peptides showed better results than G. max peptides in treating CDI. This study supports the potential treatment of CDI with natural peptides and promotes the development of specialty foods for CDI enteritis.
