Nasal microbiota

The nasal microbiota refers to the diverse community of microorganisms—primarily bacteria—that inhabit the human nasal cavity. This ecosystem plays an essential role in modulating local immune responses, protecting against pathogenic colonization, and influencing susceptibility to both acute respiratory infections and chronic inflammatory diseases like chronic rhinosinusitis. The dominant genera in healthy adults typically include Staphylococcus, Streptococcus, Veillonella, and Cutibacterium[4]. Alterations in the composition or diversity of this microbial community have been linked to increased risk for respiratory tract infections during infancy, development or exacerbation of chronic rhinosinusitis, antimicrobial resistance carriage, and even potential neurological effects through impacts on olfactory health[1][2][3][4]. While not itself a molecular target like a receptor or enzyme, recent research has explored therapeutic strategies aimed at restoring healthy nasal microbial communities—such as nasal microbiota transplantation—to treat disease states associated with dysbiosis. These approaches are still experimental; safety concerns regarding donor screening and long-term effects remain under investigation[2]. Note: "Nasal microbiota" is not a single molecule/receptor/therapeutic target but rather an ecological term describing an entire microbial population. It does not fit standard drug-target classification schemes used for receptors/enzymes/transporters/etc., so it should be flagged as "is_incorrect: true" if strict molecular targeting is required.
