>>12533584>>12533596The use of bacteriophages to treat infections is almost (if not older) than that of modren antibiotics but fell out of favour in the west sometime in the 60s/70s if I recall correctly. Former soviet countries practiced it far longer and in some still do but there are limitation to phage therapy too.
One interesting modern example of phage therapy making a comeback in the West was the use of a phage cocktail applied to Cf patients dressings of a wound infected with a very drug resistant mycobacterial strain.

>>12536650>Why do we not just always use three+ different antibiotics operating under different mechanisms at once?Side effects, route of administration (not all can be taken orally or have optimum efficacy if done so, costs of taking a cocktail of drugs instead of one targeted one. These are just a few I can think of.
