Question
Tularemia is caused by an organism that typically enters the skin and spreads to the
A) lung.
B) heart.
C) kidney.
D) lymph nodes.
Solution
Tularemia is caused by the bacterium Francisella tularensis. This bacterium typically enters the body through the skin, often through a tick or deer fly bite, or through handling an infected animal. Once inside the body, the bacterium can spread to various parts of the body.
The most common place it spreads to is the lymph nodes, causing them to become enlarged and painful. This is known as glandular or ulceroglandular tularemia, which are the most common forms of the disease. Therefore, the correct answer is:
D) Lymph nodes.
