Some people think it would be great if scientists could wipe out all the microbial bugs! Should we do it, and why or why not?
We get a lot of requests to track down the nasty bugs that are making people sick. It's true that some microbes cause health problems such as strep throat, chickenpox and the common cold. Unfortunately, because a small number of microbes cause disease, all microbes have got a bad rap.
It seems only a few bad microbes get almost all the press. You just don't hear as much about all the many GOOD things microbes do every day.
