Staphylococci: novobiocin test to distinguish coagulase negative staphylococci [ID 848]
Staph epidermidis stays away from the novobiocin disc like an epidemic.
 Therefore, epidermidis is sensitive to novobiocin.
Staph saprophyticus, much friendlier, comes up to the disc and says, "'sap?'" [short for "whassup?", ie "what's up"].
 Therefore, saprophyticus is novobiocin resistant.
