Phage therapy subjects from Sellano town : Why Mycobacteriophage DS6A?

From Wikipedia

If the target host* of a phage therapy treatment is not an animal the term "biocontrol" (as in phage-mediated biocontrol of bacteria) is usually employed, rather than "phage therapy".

"In silico"
From:"Genomics,Proteomics and Clinical Bacteriology", N.Woodford and Alan P.Johnson

Phrase that emphasizes the fact that many molecular biologists spend increasing amounts of their time in front of a computer screen, generating hypotheses that can subsequently be tested and (hopefully) confirmed in the laboratory.

Why Mycobacteriophage DS6A?

About eighteen years ago I was working on Mycobacterium tuberculosis and I was studying a specific Mycobacteriophage: DS6A. Before picking out this phage I had spent a lot of time for reading documents and scientific journals.
I selected this phage for its lytic power expressed on Mycobacterium tuberculosis complex (M.tuberculosis, M.bovis, M.africanum, M.microti).
The lytic activity of phage DS6A is always expressed on all strains collected from any part of the world. In the meanwhile C.R.Merril and colleagues wrote a scientific paper:
“ Long-circulating bacteriophage as antibacterial agents” Proc. Natl. Acad. Sci. USA, published in 1996.
After this reading I thought a potential application of phage DS6A for a peculiar pathological situation in the Man:Multidrug-resistant (MDR) tuberculous meningitis and AIDS.
This crazy idea was originated by one of features of Mycobacteria : the intracellular location. Mycobacteria reside in monocytes, reticuloendothelial cells and giant cells but when cause Meningitis they remain out off the cells and are available for a phage attack by intrathecal administration.
On that occasion I wrote a letter to C.R. Merril and intentionally I did not write to him my idea.
Today Antimicrobial (Drug) Resistance is a big problem and Phage Therapy if properly works might be a valid and cheap solution to the antibiotics.

Monitoring

Year 2010 (2011,2012,2013,2014,2015,2016,2017,2018..)

- At present there are Strict rules about Drugs.

Positive and continuous trend in the request of new anti-bacterial drugs.

Year 2025?- Drug regulations changes by a swing in public Opinion and Phage Therapy Units starting inside the Hospitals.

I have read a lot of scientific studies concerning different topics about Phage Therapy and many opinions from the academic world. These comments about the use of Phages in therapy are often sceptical and also sarcastic.
I share some their opinion but the trend of antibiotic resistance is characterising by a relentless advance. In the absence of new antibiotics we are obliged to act with fairness and to weigh the pros and cons of Phage therapy.

Phage Therapy is better than nothing.

Potential application of Mycobacterium phages in Buruli disease

I have been studying since January 2009 if Phage Therapy could be considered in Buruli ulcer. Patients shed large numbers of bacilli from their wounds.
"In the first stage of disease Mycobacterium ulcerans bacilli are typically found extracellularly, where it might be immediately accessible by phages."
Children under the age of 15 years ( range 2-14 years) are predominantly affected.
After my trip in Ivory Coast it is my personal project and I am exploring if this working hypothesis is possible.

Theory and Practical Applications of Phage Therapy in Human Field.

I must remember that Phage Therapy is not equivalent to the Antibiotic Therapy but in some pathological situations, with well definite circustances and when we have a bacterial infection caused by bacteria resistant to all antibiotics, in that case Phage Therapy would remain the unique and possible treatment with a tangible chance of succes.

A complete and schematized process for working with Phages by Phage Cocktails. Phage Therapy is praticable both in Veterinary Science and in Agricultural and Food Industry. Phage Therapy in Human field is, on the contrary, a demanding job.

I'd like to explain several key points of Phage Therapy, for example:

How to prepare Phages
How to select Phages
How to purify Phages
How to administer Phages

Patenting Issues and Defense of Intellectual Property
One relevant factor in the development of all bacteriophage-based therapies is their intellectual property status, because the idea of using bacteriophages as therapeutic tools is almost a hundred years old, and as such , unpatentable.

Main Obstacles to Phages Therapy

• Pervasive fixation on chemical antibiotics within the clinical establishment.

• Resistance of the pharmaceutical sector, which is heavily invested in chemical antibiotics.

• Physicians' reluctance to forego wide-spectrum antibiotics in favor of the highly specific phages.

• Structural and functional reorganization required for a coordinated and responsive diagnosis-production-administration chain.

• Pervasive aversion within the biotech research establishment to revert to "archaic" microbiology.

• Need to constantly adapt and refresh phage preparations in response to pathogen evolution.

• Delay between clinical presentation and antibacterial administration.

• General disregard for Russian research and clinical practices.

• Concerns with bacterial evolution of resistance to phages.

• Lack of a regulatory reference basis.
