Unraveling the Interconnection Patterns Across Lung Microbiome, Respiratory Diseases, and COVID-19

Albeit the lungs were thought to be sterile, recent scientific data reported a microbial microbiota in the lungs of healthy individuals. Apparently, new developments in technological approachesincluding genome sequencing methodologies contributed in the identification of the microbiota and shed light on the role of the gut and lung microbiomes in the development of respiratory diseases. Moreover, knowledge of the human microbiome in health may act as a tool for evaluating characteristic shifts in the case of disease. This review paper discusses the development of respiratory disease linked to the intestinal dysbiosis which influences the lung immunity and microbiome. The gastrointestinal-lung dialogue provides interesting aspects in the pathogenesis of the respiratory diseases. Lastly, we were further interested on the role of this interconnection in the progression and physiopathology of newly emergedCOVID-19.

Automated summary

Recent scientific data has shown the presence of a microbial microbiota in the lungs of healthy individuals, and advancements in technology, including genome sequencing methodologies, have helped identify the role of gut and lung microbiomes in respiratory disease development. Imbalances in gut microbiota can influence lung immunity and microbiome, impacting the pathogenesis of respiratory diseases. This interconnection may also play a role in the progression and physiopathology of newly emerged COVID-19.
