To be fair, they probably said the same about penicillin when it was discovered.

And in a way penicillin is too good to be true, now that bacteria are widely resistant to it and many other antibiotics.

[eliben]

Penicillin probably saved at least tens of millions of lives, and other antibiotics even more. Yes, some strains of bacteria are developing resistance, but even today antibiotics are saving many many lives every day.

Can we crispr resistant bacteria to be susceptible to penicillin/antibiotics again?

[ccozan]

Interesting idea. So you would first infect voluntarily with a custom virus that targets the bacteria by using CRISPR to remove the DNA strand of the resistance, then simply use the usual antibiotics to kill it.

[mathw]

At that point couldn't you just make a custom virus which kills the bacteria, so it happens in one step?

[omarchowdhury]

Doesn't erase the benefit it has had up to this point.

The millions saved haven't been eroded if some bacteria now are developing resistance.
