Bacteriophages are a long-standing candidate to replace antibiotics These are viruses that can kill those that are pathogenic to our body. Their advantage over antibiotics is that bacteria simply cannot "get used to them" by developing resistance. Of course, pharmaceutics "tunes up" bacteriophages in the right way to make targeting more successful. These special viruses are already used in medicine, but only rarely - more often antibiotics are preferred. Why, since bacteriophages are more effective? On the one hand, yes. But their effect is too "exclusive" - many viruses eliminate only a few or even only one variant of bacteria. This complicates their prescription, because the causative agent of infectious disease is not always known🙌🏻
