Bacteria: Good or Bad?

When you hear about bacteria, isn’t your first reaction to think “Yuck!  Bacteria bad, anti-bacterials good!”

Well, one of the newest fields in biological research today (only 10 years old) is focused on the importance of good bacteria that we are exposed to throughout our lives.  Recent research has shown that the more we try to avoid bacteria, the worse off we are in regards to our immune systems.  It turns out that the more bacteria we are exposed to early childhood, the stronger our immune systems will be as we grow older.

Here are two articles that I think you might find interesting.  The first is how bacteria and allergies are related.  The second is an episode from NPR’s Science Friday about the interaction of the bacteria in your body and its affect on your brain and your behavior.  Download the podcast and have fun learning!
