Deception on a molecular level

Deception on a molecular level
When magnified, it looks like a bunch of grapes (Greek "staphyle") or berries (Greek "kokkos") which gives it its name – Staphylococcus.

I was about to eat lunch at a local magic convention when I mentioned some examples of deception that occur in nature, and the magicians at my table were surprised. They thought that most trickery only occured between humans. It turns out that deception occurs at many levels.

Here’s an example of how chemists have deceived bacteria.

Scientists have fooled the Staphylococcus aureus bacteria into accepting small molecules into its cell wall.

"We sort of tricked the bacteria into incorporating something into its cell wall that it didn’t actually make," said David Spiegel, a Yale chemist who led a study. "It’s as if the cell thought the molecules were its own proteins rather than recognizing them as something foreign."

Since the staph bacteria uses the cell wall to relate to its environment, this might be the first step in figuring out how to disturb the bacteria’s ability to interact with human cells.

The type of bacteria that were tricked are responsible for staph infections, pneumonia, strep throat and other diseases. About 30% of us carry this staph bacteria in our noses or on our skin, and in most cases, it’s not a problem. But if it gets into our bloodstream or other organs, it can kill us. You might have heard of the staph  called MSRA, which is a "superbug" that has become resistant to antibiotics. In the U.S., as many as 19,000 people each year die from MRSA.
