Abstract

Enterotoxigenic Escherichia coli (ETEC)‑induced diarrhea is a devastating disease and one of the third leading causes of infectious disease‑associated mortalities worldwide. Despite recent advances in the identification of the association between gut microbiota and diarrhea, a lack of understanding exists on the status of gut microbiota in rats treated with ETEC. In the present study, a rat model of Escherichia (E.) coli O101‑induced diarrhea was established. The diarrhea incidence and index, as well as histological changes, were assessed. In addition, Illumina MiSeq sequencing of V3‑V4 hypervariable regions of 16S ribosomal RNA was employed to investigate the changes in the gut microbiota profiles in the feces of the diarrhea rats. The results indicated that E. coli O101 increased the diarrhea index and injury in the intestinal tissues, whereas it decreased the bacterial richness and shifted the distribution pattern of the bacterial communities in the phylum, order and genus levels in the fecal samples. Notably, the proportion of bacteria Prevotella, Enterococcus and Akkermansia was significantly decreased, while the pathogenic bacteria Escherichia/Shigella were significantly increased in diarrhea rats. Taken together, the gut microbiota is closely associated with E. coli O101‑induced diarrhea in lower microbial diversity and dysbiosis of gut microbiota at different taxonomical levels.
