Old Y*utube drama. Coffee Break vs Kurzgesagt

Antibiotic resistance is certainly a major health issue. Id point out their Phage Therapy video as an example of what I am talking about. On the surface bacteriophages makes a lot of sense as an alternative to antibiotics. They pose basically no harm to humans, they are highly specific so they wont harm the human micro biome, and they naturally evolve with bacteria so we wont have to worry about engineering our way out of immunity. The issue is Phages are so highly specific one phage can often only infect one strain of one species of bacteria, so we would need far more specific diagnosis cowtools and we would need to have thousands if not hundreds of thousands of phages on hand to treat any possible strain. We would also need to be constantly collecting and identifying new phages to keep up with bacterial evolution. Imagine the regulatory nightmare of needing to test so many treatments.

This is the reason why despite phage therapy being as old as the ussr and it being successfully used on multiple patients it is no where close to wide medical adoption and likely wont be barring the incredible discovery of one unspecified phage or the creation of genetically engineered phages.
