Résumé
The effect of dietary intervention on intestinal flora and health has become a research focus in the medi-cal and health field. In terms of development, intestinal flora may become an important target for the study of the influence of dietary styl, health food and traditional Chinese medicine on human health. However, due to the complexity of intestinal flora,high standard for animal models that is applied to researches on the relationship between intestinal flora and dietary in?terference is required. It has been claimed that there is no living microorganisms and parasites inside germ?free animals, thus they are the most widely used basic animal models in the study of intestinal flora. Therefore, it is a common way to ap?ply germ?free animal for generating human flora animal model to study the relationship between diet, flora and health. In this paper we will review the researches and applications of human source flora animal models established by germ?free ani?mals and the influence of dietary intervention on gut microbiota.
