| Outline of Final Research Achievements |
The intestinal tract is one of the first organs acquired by multicellular organisms in the course of evolution. Because of its essential role in the digestion and absorption of food, its nutritive environment provides an ideal niche for commensal microbes, the effects of which are considered tremendous on hosts. Drosophila melanogaster, an invertebrate model organism, certainly possesses a gut, and its microbes could be used for investigating host-microbe interactions. However, generating and maintaining “germ-free” Drosophila is rather challenging. In this study, we established a solid and perhaps the first method for establishing germ-free flies, using a vinyl isolator and fly food with a specific composition. This germ-free fly technique could provide a pivotal basis for analyzing gnotobiotic Drosophila, which will improve our understanding of evolutionarily conserved host-microbe interactions in the intestine.
