Phage therapy uses bacteriophages—viruses that infect and lyse specific bacteria—as precision antimicrobials. Unlike broad-spectrum antibiotics, phages target specific bacterial species or strains, sparing the commensal microbiome.

In the WikiBiome framework, phage therapy represents a targeted ecological intervention (Karen's Brain Primitive 5)—suppressing specific pathobionts without collateral Dysbiosis.

Advantages Over Antibiotics#

Species-specific: Each phage infects a narrow host range, preserving the broader microbiome. Biofilm penetration: Phages encode depolymerases that degrade biofilm extracellular matrix—addressing the biofilm resistance problem that defeats antibiotics. Self-amplifying: Phages replicate at the site of infection, increasing in number where the target pathogen is most abundant.

cobalt (Co)-evolution capacity: Phage-resistant bacterial mutants often lose virulence factors, creating a fitness trade-off.

Phage Cocktails#

Phage cocktails combine multiple phages targeting the same species (different receptors) or different species in a polymicrobial infection. The cocktail approach. Reduces emergence of phage-resistant mutants.

Broadens the host range within a target species. Can address polymicrobial biofilms when combined with Functional Shielding-disrupting antifungals.

Metal Connection#

Phage therapy intersects with metallomics in two ways. Some phage endolysins are zinc-dependent metalloenzymes—zinc availability affects lytic activity. Phage therapy can replace antibiotics in scenarios where metal-antibiotic co-selection (Co-Selection) drives AMR—phages exert no metal-resistance selection pressure.
