The key facts

  • More than 60 recommendations for personalized bacteriophage therapy have been developed and published in Nature Medicine
  • The work was led by the German Society for Infectious Diseases; 20 professional organizations and two patient organizations took part in the consensus process
  • The approach is intended for cases where antibiotics are ineffective, unavailable, or inapplicable

A consensus standard for treating bacteria with viruses

An international group of experts has developed consensus recommendations for personalized bacteriophage therapy — a method in which infections are treated with viruses capable of infecting and destroying bacteria. The document contains more than 60 recommendations and has been published in the journal Nature Medicine. The work was led by the German Society for Infectious Diseases, and the consensus process involved representatives of 20 professional organizations, international experts, and two patient organizations, reports Gazeta.Ru.

Why therapy must be tailored individually

A key feature of phages is their selectivity: a virus effective against one bacterial strain may fail against another. Therefore, for personalized therapy, the pathogen must first be identified and its susceptibility to specific viruses tested. It is precisely this laboratory stage that distinguishes the personalized approach from the use of ready-made preparations.

What the recommendations cover

The document describes the full cycle of treatment: selection and laboratory testing of phages, production of preparations, quality control, methods of administration, and patient monitoring. Particular attention is given to documenting treatment and collecting data for subsequent research. The delivery method depends on the type of infection — topical application, inhalation, or intravenous administration are all possible.

Who this is intended for

This approach is considered for difficult situations where standard treatments have proven ineffective, unavailable, or inapplicable — that is, primarily for patients with antibiotic-resistant infections. Earlier, as Gazeta.Ru notes, a biologist had already called phage therapy a possible replacement for antibiotics; the new document moves this field from scattered clinical cases into the framework of agreed rules, bringing order both to the selection of preparations and to the collection of data on treatment outcomes.
