I don't understand this bit: ". . . resistant bugs have grown more numerous and by sharing DNA with each other, have become even tougher to treat . . . "

In short, one thing that happens is that they exchange small fragments of DNA (called plasmids). Those fragments can contain the information necessary for the resistance.
