What are the symptoms?

I vaguely remember that I used to get a lot of staph infections when I was little. I remember that we put bacitracin on them, but that is all I remember. I am worried that my kids will get a Mercer Staph infection and I won’t realize what it is. What are the symptoms for this kind of infection? Are there different types of staph infections? Maybe I had a different type when I was little. What do you do about staph infections if you get them? How do you treat them? Can anyone tell me where I can find out more about them?
