Do you have even the basic knowledge of the mechanism of drug resistance in bacteria?

Please explain it in detail for us ignorant masses.

While you are at it, also explain how some tumors become resistant to chemo.

I see that you're to pound your chest in self agrandisement.

"explain how some tumors become resistant to chemo"

First prove that it is the tumor's resistance, rather than the destruction of the body's immune system due to the massive toxic attack that chemo obviously is.

Come on back in 20 or 30 years to let us know, ok?
