In a creative stroke inspired by Hollywood wizardry, scientists have designed a simple way to observe how bacteria move as they become impervious to drugs. The experiments are thought to provide the first large-scale glimpse of the maneuvers of bacteria as they encounter increasingly higher doses of antibiotics and adapt to survive—and thrive—in them.
Bacteria (white) grow up to the boundary where they can no longer survive. Mutants, capable of surviving the higher concentration of antibiotic appear and invade the new band. Subsequent steps require further mutations. After about 11 days, resistance to over 1000 times as much antibiotic as was originally toxic evolves.
The MEGA-plate with an exponential trimethoprim gradient (0-3-30-300-3000-300-30-3-0 MIC).
This movie was compiled from time-lapse imagery every 10 minutes for 11.7 days, and played at 30fps (18000X speed). Each second of video is approximately five hours of real time.
Condensation on the lid is visible in the first several frames, and a single contaminating colony appears on the plate.
The MEGA-plate with a CPR gradient as in fig. S1 (0-20-200-2000-20000-2000-200-20-0). Movie was compiled from time-lapse imagery every 10 minutes for 14.2 days, and played at 30fps (18000X speed).
