Evolution Of Bacteria Against Antibiotic Drugs

A research team from Harvard Medical School created a time-lapse video that shows how bacteria is growing and evolving resistance to drugs. The researcher set up a giant 2-by-4 foot petri dish called MEGA (microbial evolution growth arena plate). On the right side of the plate where antibiotic levels were zero grew Escherichia coli (better known as E.coli) bacteria. The bacteria is shown in milky white on the black background. Over two weeks, a camera took periodic snapshots of the bacteria mutating. Through the process of successive mutations shows how bacteria that are normally …
