CRISPR already exists. This can easily be used to target antibiotic resistance genes and there are many examples in literature of this. Plasmid and phage as vector. Easy stuff. However, cane toads and wabbits and intentional release of GMOs leaves something to be desired for gene technology regulators.
Antibiotics are the way, but require targeted combination therapy, not a doctor’s gut feeling.
Taking the time to learn gimp is worthwhile. Its really powerful once you know how to use it IMO
