On driving factor is the (over)use of antibiotics in animal agriculture. It's weird the article touches this issue in just one sentence...

"Over 70 percent of antibiotics sold in the United States are given to livestock, including cattle, which translates to significant human health impacts."

"Unlike with human medicine, however, antibiotics are often fed to cattle as a preventative measure, rather than as a treatment."

"Antibiotic resistance in cattle does not only affect the health of the cattle, it impacts people as well because many of the antibiotics given to cattle are also used in human medicine. Eating meat or consuming milk from an animal with antibiotic-resistant bacteria may infect a human with that same resistant bacteria"

"I see the disinfectant, where it knocks it out in one minute. And is there a way we can do something like that by injection inside or almost a cleaning, because you see it gets in the lungs and it does a tremendous number on the lungs."

"I said supposing you brought the light inside the body, which you can do either through the skin or in some other way. And I think you said you're going to test that too... So, we'll see, but the whole concept of the light, the way it kills it in one minute - that's pretty powerful."

Wasn't there a whole thing about bacteriophage treatment and supplement to antibiotics?

Like, "if bacteria develop resistance to one it reduces resistance to the other!" kinda deal?
