Conventional Rationale
Long COVID patients experiencing secondary bacterial infections are treated with broad-spectrum antibiotics as standard of care.
Why It's Counterproductive
The Long COVID microbiome is already characterized by critical depletion of SCFA-producing anaerobes — Faecalibacterium, Roseburia, and Bifidobacterium. Bernard-Raichon et al. demonstrated that COVID-associated dysbiosis drives bacterial translocation and bacteremia, creating a self-perpetuating inflammation loop Bernard Raichon2022 dysbiosis translocation bacteremia covid.
Broad-spectrum antibiotics destroy the residual protective anaerobes that remain, further collapsing the barrier against translocation. This worsens the very loop driving Long COVID persistence: dysbiosis → barrier breakdown → translocation → systemic inflammation → further dysbiosis.
Alternative Approach
- Narrowest-spectrum antibiotic targeting the specific pathogen when antibiotics are truly necessary
- Co-administer targeted probiotics to preserve and restore SCFA-producing communities
- Evaluate necessity — determine if the infection truly requires systemic antibiotics vs. supportive care
