Graphic Encouragement to Wash Your Hands
Each batch of agar contained a little bit of cefoxitin, an antibiotic that should prevent any ordinary bacteria from growing on the plates.
After a little bit of incubation, the first plate (left) was covered in bright red colonies. It provided damming evidence that the infection can easily be spread by hand.
The second plate (right) was completely free of bacteria. It showed that disaster can be averted very easily. By taking just a minute to lather up, anyone who works with patients can fight the spread of antibiotic-resistant bugs.
