Abstract

Allergic diseases are becoming a major healthcare issue in many developed nations, where living environment and lifestyle are most predominantly distinct. Such differences include urbanized, industrialized living environments, overused hygiene products, antibiotics, stationary lifestyle, and fast-food based diets tend to reduce microbial diversity and lead to impared immune protection, which further increase the development of allergic diseases. In the same time, studies also showed that modulating microbiomes can ameliorate allergic symptoms. Therefore, in this paper, we aimed to review recent findings on the potential role of the human microbiome in the gastrointestinal tract, surface of skin and respiratory tract for the development of allergic diseases. Furthermore, we addressed a potential therapeutic or even preventive strategy for such allergic diseases by modulating the human microbial composition.
