FTA: The misuse of antibiotics was a big reason for the rise — unfinished or unnecessary prescriptions that didn’t kill the germs made them stronger.

Not my field, but IIRC this is misleading: When an unfinished or unnecessary antibiotic doesn't kill all the germs, an unintended consequence is that the antibiotic "clears the field" for the surviving (and, ipso facto, more-survivable) germs to reproduce and spread — thus strengthening the remaining germ population.
