Final answer:
The Schick Skin Test is used to detect susceptibility to diphtheria, a respiratory infection caused by the bacterium Corynebacterium diphtheriae.
Step-by-step explanation:
The Schick Skin Test is used to detect diphtheria, which is caused by the Corynebacterium diphtheriae. Diphtheria is a severe respiratory infection that can lead to the formation of a pseudomembrane in the throat, which is a classic sign of the disease. The causative agent, Corynebacterium diphtheriae, is a gram-positive bacterium that releases a toxin causing the symptoms of the disease.
The Schick Test assesses an individual's susceptibility to diphtheria by introducing a small amount of the toxin and observing the skin's reaction. A positive Schick Test indicates a lack of immunity to diphtheria, and further immunization may be required.
