Cadmium exposure induces changes in gut microbial composition and metabolic function in long-tailed dwarf hamsters, .

Numerous studies have demonstrated that exposure to cadmium disrupts the diversity and composition of the gut microbiota, resulting in damage to organ tissue. However, there remains a lack of comprehensive understanding regarding the broader ecological reality associated with this phenomenon. In this study, we conducted a thorough evaluation of the effects of different concentrations of Cd (6, 12, 24, and 48 mg/L) over a period of 35 consecutive days on the organ viscera and the gut microbiota of long-tailed dwarf hamsters, (Rodentia: Cricetidae), using histopathological analysis, 16S rDNA, and metagenome sequencing.

Effects of dietary nutrients of the gut microbiota in the long-tailed dwarf hamster ().

Gut microbiota is a key factor in maintaining the dietary and metabolic homeostasis of small mammals. To explore the effect of diet on the gut microbiota of the long-tailed dwarf hamster (), 16S rDNA high-throughput sequencing combined with bioinformatics analysis was used to investigate the succession process of the gut microbiota and effects of different nutrients on the composition and function of the gut microbiota. The results showed that diet structure can significantly influence the composition and function of the gut microbiota, as well as the health of animals.
