Making Doorknobs Brass Could Stop The Spread Of Superbugs
Brass door knobs, handles and handrails should be brought back into common use in public places to help combat superbugs, according to scientists.
Researchers have discovered that copper and alloys made from the metal, including brass, can prevent antibiotic resistance in bacteria from spreading.
Plastic and stainless steel surfaces, which are now widely used in hospitals and public settings, allow bacteria to survive and spread when people touch them.
Even if the bacteria die, DNA that gives them resistance to antibiotics can survive and be passed on to other bacteria on these surfaces. Copper and brass, however, can kill the bacteria and also destroy this DNA.

14. I wonder of that is why door knobs were originally brass in the first place.
Of course they didn't know about pathogens back then, but somebody must have realized that disease was less common when door handles were made of brass.
