Diarrhea-predominant irritable bowel syndrome (IBS-D) is common among the captive South China tigers in zoos. 16S rRNA gene sequencing was performed to demonstrate the compositions and structures of the gastrointestinal microbiota of this species with IBS-D. Their healthy (F1) and mushy (F2) feces were allocated into two groups. A total of 21 and 31 fecal bacterial communities of major phyla and genera were detected, respectively. The F1 and F2 groups had five common microbiotas at the phylum level (Firmicutes, Proteobacteria, Fusobacteria, Actinobacteria, and Bacteroidetes). Among the five phyla, the abundance of Bacteroidetes in the F2 group was significantly lower than that in the F1 group. The diversity level of fecal microbiota within the mild-diarrhea stool was also significantly lower than that of the healthy counterpart. Thirty-two metabolites were correlated to four genus-level bacteria (Bacteroides, Pseudoclavibacter, Streptococcus, and Ruminococcaceae-UCG-005). Due to its normal role in protein degradation and metabolism, we hypothesized that the lower abundance of Bacteroides within the F2 group could be associated with the IBS-D symptoms. Therefore, this work implied that ameliorating the daily diet with a supplement of probiotics, such as Bacteroides, could improve the gut health of this species.
