Answer

Inoculation of tellurite or Loeffler media with swabs taken from the nose, pseudomembrane, tonsillar crypts, any ulcerations, or discolorations. Identification is accomplished through observation of colony morphology, microscopic appearance, and fermentation reactions. Any diphtheria bacilli isolated must be tested for toxin production.

Obtain throat and pharyngeal swabs from all close contacts. [10]
