What is Phage Therapy? What role does it play in the face of antibiotic resistance?

Phage Therapy

Phage therapy is a medical procedure that can have very important implications in our relationship with bacteria. Below we delve a little deeper into this medical therapy and its impact on our health.

What is Phage Therapy?

According to doctors Jordi and Nuria Reina in their article for the NCBI, phage therapy is an alternative treatment that consists of phage use to solve the inconvenience of the bacterial resistance that some bacteria have developed against drugs that should kill them.

The phages are viruses that infect bacteria by injecting your genetic material into them. The phage expands within the bacterium, ultimately causing it to explode, thus allowing the phages to expand to infect more bacteria.

Given the phages can destroy bacteria, its use has been proposed to destroy bacteria dangerous to the human body because despite the fact that phages cannot destroy all possible species of bacteria they can eradicate those that have become resistant to antibiotics.

Problems around phage therapy

As promising as phage therapy is, there are some drawbacks that still prevent it from being a commercial and mass-use treatment in medicine.

The pharmaceutical industry has made no further effort to prepare phages for human use through medical treatment, so this therapy is not fully developed, and Not all the implications it may have on us are known.

On the other hand, world health authorities have not regulated the medical use of phages because it was not expected that they could be used for the benefit of patients, so there are no production, quality, or safety guidelines.

Many studies are still required to determine the feasibility of phage therapy as a completely controllable and safe therapeutic procedure for the patient’s health, it cannot yet be used on a large scale.
