QUESTION 215

Pneumonia is an infection, and Rickettsia are bacteria that can cause infectious diseases including pneumonia. Climate, genetics, and helminthiasis/ascariasis are not typical causes of pneumonia.

The Schick test is specifically used to detect susceptibility to diphtheria. Tetanus, tuberculosis, and polio have other diagnostic tests.

Adenoids are lymphoid tissues located behind the nasal cavity. Bronchioles are in the lungs, tonsils are in the throat, and paranasal sinuses are air - filled spaces in the skull, not lymphoid tissues behind the nasal cavity.

Answer:

A. Rickettsia
