Suspect colonies should be checked for the characteristic coryneform morphology on Gram's stain. Albert's stain should not be used for colonies isolated on tellurite-containing medium as this medium inhibits the formation of volutin granules. Toxigenicity can be tested by Elek's method. A rich, ...

As these agents are frequent contaminants of clinical specimens or commensals of skin or nasopharynx, it is often difficult to determine if busy clinical laboratories should spend time and resources identifying these bacteria beyond reporting morphology or Gram stain characteristics (Weinstein, 2008). ...
