Microbiome in the primary prevention of allergic diseases and bronchial asthma

Tremendous progress in the ability to identify and test the function of microorganisms in recent years has led to a much better understanding of the role of environmental and host microbiome in the development of immune function, allergic sensitization and asthma. In this review, the most recent findings on the relationships between environmental microbiota, respiratory, intestinal microbiome, the consequences of early-life microbial exposure type and gut-lung microbial axis and the development of asthma and atopy are summarized. The current perspective on gut and airway microbiome manipulation for the primary prevention of allergic diseases and asthma is also discussed. (C) 2018 SEICAP. Published by Elsevier Espana, S.L.U.
