# Microbiome disruption enables pathogen invasion through competitive displacement
|
|
|
|
The Human Microbiome Project demonstrated that broad-spectrum antibiotic use severely disrupts the microbiome through indiscriminate killing of non-pathogenic members. Dorit explains: "The indiscriminate killing of nonpathogenic members of the microbiome makes it easier for pathogens to invade otherwise stable, occupied environments. As a result, pathogens that would not have a real chance of establishing themselves, most notably the aptly named Clostridium difficile, can run the table."
|
|
|
|
This reveals a critical vulnerability: community stability depends on maintaining functional membership, not merely on the absence of pathogens. A stable microbiome resists pathogen invasion through competitive exclusion—occupied niches are unavailable. Removing non-pathogenic members creates ecological space that pathogens exploit.
|
|
|
|
Long-term consequences are severe: "Over the longer term, repeated antibiotic use may prevent the microbiome from ever recovering its original composition. Instead, such perturbed ecosystems may settle on a new composition that includes different species, many of them resistant to antibiotic treatment." The system can reach a new stable state that is functionally equivalent but compositionally different—and potentially more pathogenic.
|
|
|
|
Implication for superorganism robustness: systems that appear robust to targeted removal of individual components may be fragile to removal of functional categories. Stability depends on maintaining diversity within functional roles, not just maintaining the system's overall function.
