Paige has cultured staph before, and a lot of the times, the Dr's will let it grow. Staph has a capability to fight off some of the "badder bugs" naturally, and Dr's also want to see HOW it will grow. There are some people who culture staph regularly, it's just part of their natural growth. So, it's totally common for Dr's to forgo treatment. I wouldn't worry, as long as your DD isn't showing any unusual symptoms.
