I have found a simple explanation of what phage therapy is and how it works.
The phage virus attaches itself to the surface of the bacteria cell. It injects its DNA into the cell itself. The virus is alive, and this is how it reproduces. Within a just few minutes, the DNA becomes a phage factory, hijacking the bacteria’s own reproductive mechanism and turning out new copies of the virus, until they explode through the cell wall, killing the bacteria (such as MRSA) and releasing phages that rampage in search of other identical cells, and only those cells, until all the bacteria are gone.
Western medicine hasn’t paid much attention to phage therapy since the discovery of antibiotics but more and more interest is being generated about phage therapy as we begin to do battle with the superbugs that antibiotics have created.
Phage therapy is truly the way of the future if only the pharmaceutical companies will allow it into mainstream medicine but they will resist its induction because they cannot make the money marketing viruses that they do making the thousands of antibiotics that have created MRSA and other superbugs. Public education and demand will be what forces phage therapy back into western mainstream medicine.
