Microbial dysbiosis

Microbial dysbiosis refers to a disruption or imbalance of the normal microbial communities (microbiota) that inhabit body sites such as the gut, skin, or mucosa. In healthy individuals, these communities perform essential roles in digestion, immune regulation, and protection against pathogens. When this balance is disturbed—due to factors like antibiotics, poor diet, stress, infection, or environmental exposures—the resulting dysbiosis is associated with a wide range of diseases, including inflammatory, metabolic, neurodegenerative, and malignant conditions. Therapeutic strategies aim to restore a healthy microbiome through dietary changes, targeted antibiotics, probiotics, prebiotics, or fecal microbiota transplantation. However, as a community-level state rather than a discrete molecular entity, "microbial dysbiosis" is not a canonical molecular target or receptor, but rather a disease process or condition to be managed or corrected. In summary: "Microbial dysbiosis" describes an abnormal community state, not a molecular target or receptor. It is critical in health and disease, but not a druggable entity itself; instead, interventions act to shift the overall community composition or function.
