So does that mean that using bactericide antibiotics when you're sick is bad for you.

The fact that some bacteria can be good and bad for you at the same time is really interesting. I never thought that this could be possible. My dad is always talking about E. Coli, but I never actually knew what it was. I always thought it was some weird disease, I am so excited to tell him that it's good as well as being bad for you.

It is cool that bacteria can be good and bad for you. There are a lot of things that can be good and bad for you. It is funny because most people think of bacteria as something bad and something that makes you sick. We should think of bacteria as a general name, and only some bacteria can be bad for you. We could think of bacteria as helpful things, but there are some bad ones to watch out for.

This article on bacteria combines the study of bacteria with genetics. It’s interesting that bacteria can affect brain development and behavior. The article is wrong when it says that “bacteria is far too small to see with the naked eye.” Giant bacteria like Thiomargarita namibiensis can be seen with the naked eye. There is a lot to learn about bacteria and how it affects the human body.
