Effects of Microbial Transfer during Food-Gut-Feces Circulation on the Health of Bombyx mori

The body often appears unwell after habitual dietary changes. The domestic silkworm (Bombyx mori) raised on artificial diets is a good model to explore the relationship between dietary changes and the balance of intestinal microbes. In this study, the food-gut-feces microbial model was established, and some potential key genera that could regulate the balance of intestinal microbiota were screened out. Our findings will provide a reference for future research to further our understanding of healthy silkworm development and may even be useful for similar research on other animals.
