Antibiotic Resistance

When antibiotics fail: Phages as a precise solution

Chronic infections and resistance require a rethink in modern medicine. Bacteriophages are highly specialized viruses that specifically eliminate pathogenic bacteria without attacking your natural protective flora.

  • Maximum safety: Phages are host-specific; according to current research, side effects on human cells or beneficial intestinal bacteria are excluded.

  • High lysis efficiency: Even multi-resistant pathogens (MRE) and stubborn biofilms are actively dissolved by phage enzymes.

  • Legal classification: Legally applicable in Europe as an individual healing attempt or via magistral formulations (individual prescription).

Breaking the antibiotic vicious cycle

Many patients experience a grueling cycle: an infection is treated with broad-spectrum antibiotics. While these kill some of the pathogens, they simultaneously destroy the healthy microflora. The result? The immune system is weakened, and the remaining bacteria retreat into a biofilm – a kind of fortress that is impenetrable to antibiotics. The infection returns chronically.

Phage therapy breaks this vicious cycle. Phages do not act as a broad-spectrum chemical weapon, but as biological precision instruments. They produce specific enzymes (depolymerases) that chemically “crack open” the biofilm. Once they reach the target bacterium, they multiply millions of times until the pathogen is completely dissolved (lysed). As soon as no more pathogenic bacteria are present, the phages also disappear naturally from the body.

Chronic Urinary Tract Infections

Sustainable biofilm eradication in recurrent cystitis. Phages eliminate uropathogenic E. coli and Klebsiella pneumoniae, even if they are already resistant to reserve antibiotics, while simultaneously protecting the vaginal flora.

Respiratory Tract & Cystic Fibrosis

Increasing lysis efficiency in chronic colonization by Pseudomonas aeruginosa. Inhaled phage cocktails penetrate thick mucus and biofilms, stabilizing lung function in CF patients and significantly lowering inflammatory markers.

Skin & Septic Wounds

Precision assistance for abscesses and infected wounds. Phages act specifically against Staphylococcus aureus (MRSA). They promote wound healing by breaking down bacterial barriers that block conventional antibiotic ointments.

Post-OP & Osteomyelitis

Effective control of germs on surgical implant material. Where antibiotics fail due to lack of blood circulation in the bone, phages actively advance to the site of infection and neutralize multi-resistant pathogens (MRE) directly on site.

The Path to Therapy: In 3 Steps

  1. Diagnostics & Phagogram: Your specific bacterial strain is isolated using a sputum, urine, or wound swab. In the laboratory, it is tested exactly which phage cocktail shows the highest effectiveness against your germ.

  2. Individual Procurement: The therapy is prepared based on the phagogram. This is often done through specialized centers such as the Eliava Institute or via magistral formulation following the Belgian model (individual prescription).

  3. Targeted Application: Application is local, oral, or by inhalation. Since it is an individual healing attempt, the therapy is closely monitored by experienced medical professionals.

1. What is phage therapy?

Bacteriophages (phages) are natural viruses that exclusively infect bacteria. In therapy, they are used as a highly specific precision weapon to dissolve pathogenic bacteria (lysis). Since they do not attack human cells, the therapy is considered extremely safe and preserves the patient’s beneficial microbiome.

2. Is phage therapy legal in Germany?

In Germany, phage therapy is legally possible as an “individual healing attempt” (according to the Declaration of Helsinki). Since bacteriophages do not yet have general approval as finished medicinal products, they are usually provided via magistral formulations from specialized pharmacies, often incorporating European quality standards.

3. Why does it help when antibiotics fail?

Phages act mechanically-biologically rather than chemically. They possess special enzymes to break open bacterial biofilms (protective layers) where antibiotics fail. Furthermore, they act strictly host-specifically: they combat exactly the germ that is resistant to antibiotics without provoking new resistance in the rest of the body.
