Watch Bacteria Become Drug-Resistant Like It's No Big Deal
Bacteria march across a giant petri dish and learn to resist antibiotics in this chilling video from Harvard University Medical School.By Steven Sparkman | September 8, 2016
Just in case you need a startling reminder of how quickly bacteria become superbacteria, scientists working at Harvard University and an Israeli university built a giant petri dish that makes it easy to see the problem.
The 8-square-foot dish is coated with different levels of antibiotic, ranging from no drugs at all on the edges, to a dose that should be lethal for E. coli, to a very lethal dose, to a ridiculously lethal dose in the center.
This time-lapse shows how the E. coli spread to the next level, then different mutations evolve and each strain races to the center. The race lasts about 11 days.
