Chitosan Modulates Inflammatory Responses in Rats Infected with Enterotoxigenic Escherichia coli.

ABSTRACT: This study aims to investigate the effects of dietary chitosan (COS) on gastrointestinal pathogen resistance in mice model. For two weeks, a control group of ICR mice received a basal diet whilst the intervention group received the basal diet supplemented with 300 mg/kg COS. After two weeks, the mice fed the supplemented diet had a lower body weight. Then enterotoxigenic Escherichia coli (E. coli) was administered to the mice through oral gavage, with each mouse receiving 10⁸ CFU. At day 7 after infection, the bacterial load in the jejunum and faeces was significantly lower in the COS group than that in the control group. Moreover, the mRNA and protein levels of IL-1β, IL-6, IL-17, IL-18, and TNF-α were significantly lower in the group of mice receivi
