Abstract: Intestinal microflora is a general term for microbial communities that reside in the human intestine. In recent years, the research on diseases related to intestinal microbiota has developed rapidly. It is found that intestinal microbiota is closely related to digestive tract diseases, metabolic diseases, immune diseases, mental diseases, and lung diseases. Intestinal dysbacteriosis, mucosal barrier damaging and local immune dysfunction may be involved in a variety of disease processes. In addition, respiratory diseases such as asthma and pneumonia seriously affect human health. The intestinal microbiota is crucial in regulating immune response of lung to pathological mechanism of diseases including asthma, pneumonia and pulmonary tuberculosis. Therefore, it may be a new direction for the treatment of lung diseases by understanding intestinal microbiota in lung diseases, and identifying, describing and manipulating immunity network of pulmonary disease.
