| Outline of Final Research Achievements |
A number of animals harbor diverse microorganisms in their alimentary tract, where intimate interactions occur between the hosts and microbes. However, among these symbioses, diversity and function of gut microbiota of fish are not well-understood because of less studies using model organisms like mouse. Aim of this study is to obtain the fundamental information of gut microbiota of a model fish, medaka. Comparative analysis of community structure of gut microbiota in the domesticated and wild-caught medaka showed quite difference between the both microbiota. This result suggests that unnatural microbiota is developed by artificial domestication. Moreover, comprehensive analysis of whole body in medaka shows the specific microbiota is developed in each part, gill, skin, fin, gut, and egg in medaka, implying that medaka-associated microbiota is varied according to body parts.
