When you all get to the point where you're reading culture reports, please be aware that Staph. epidermidis is usually included in the grouping reported as "coagulase negative Staphylococcus" nowadays.
An emerging pathogen in the CNS group is Staphylococcus lugdunensis. You can read more about this group on this very informative page:

CNS is becoming recognized as a pathogen in many scenarios where it used to be considered skin flora. If you plan on going into infectious disease you may want to check out this page.
