Microbiome and disease in the upper airway

Purpose of review Microbiome refers to the genetic potential of resident microorganisms that inhabit a given niche. The exact role of the microbiome and its relation to chronic disease processes remains largely unknown, although various associations have been observed. We reviewed current literature investigating the microbiome of the upper airway by subsite (nasal cavity, sinus cavities, nasopharynx, and larynx) and its relation to chronic inflammatory disease processes. Recent findings The disruption of indigenous microbiota at a specific subsite may lead to pathogen overgrowth and increased susceptibility to infection. This has previously been demonstrated in the gastrointestinal tract and lower airways. The role of the microbiome and its relation to pathogenesis of disease in the ...
