A tray is divided into 9 sections. the end 2 sections are normal nutrient jelly. The next 2 inner sections are nutrient jelly with a normal dose of antibiotic. The next two inner sections have ten times that amount. The next two sections have 100 times the normal amount, and the final inner section has 1000 times the normal dose. (This final section has reached the solubility level of the antibiotic - they cannot dissolve any more into the jelly).
Then a drop of E.Coli is added to the end sections.
A time lapse camera shows the bacteria growing, and stopping at the barriers, and then overcoming the barriers.
After just two weeks bacteria is able to survive on the middle section; the section with 1000x the normal dose of antibiotic.
The first claim in the article about the mortality rate (<= 50%) is sensationalist and deceptive. The mention towards the end, that the mortality rate approaches half in patients with CRE bloodstream infections is more in line with the CDC press release the Wikipedia Article links to http://www.cdc.gov/media/releases/2013/p0305_deadly_bacteria... (I edited the Wikipedia page to reflect this same point.. journalists, crosscheck your sources)
Here's a short segment from a recent BBC TV programme ('Defeating the Superbugs') showing bacteria evolving antibiotic resistance.
