More to the point though, any time antibiotics are used the bacterium with antibiotic resistance takes over. There is a reason that it is often spread in hospitals, where sick people on antibiotics are, and in pig farms where ridiculous loads of antibiotics are used to increase growth rates.

What is necessary is breaking the chain of spread from antibiotic-treated niche to antibiotic-treated niche, and making sure there aren't places like said pig farms where the selective pressure is constantly applied.
