Research progress on the effect of symbiotic bacteria in Drosophila gut on its host

Abstract:

It is believed that symbiotic bacteria in the gut form an important part of animals, which play a significant role in the growth, development and health of the host. In recent years, it has attracted more attention on a national and international level. Drosophila melanogaster is an excellent model for studying the function of intestinal flora and has made important progress in the relationship between symbiotic gut bacteria and their host. In this paper, we first summarized the composition and characteristics of intestinal microbes in Drosophila, we then reviewed the roles of symbiotic fly gut bacteria on the host growth and development, nutrition and metabolism, behavioral response, longevity, immunity and disease. This will provide some theoretical rationales and new ideas for the study of the function of the gut symbiotic bacteria and the gut health in human.
