Multiple Choice

The disease tuberculosis (TB) is a serious bacterial infection characterized by granulomas typically found in the lungs. What characteristics would a TB granuloma have?

A large mass of immune cells surrounding the Mycobacterium tuberculosis thus stopping the spread of bacteria.

A region of scar tissue created by Mycobacterium tuberculosis.

A region of tissue growth to heal the damage caused by Mycobacterium tuberculosis.

Verified step by step guidance

Understand that tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis, which primarily affects the lungs.

Recognize that a granuloma is a collection of immune cells that forms in response to chronic infection or inflammation, serving to contain the pathogen.

Identify that in TB, the granuloma is primarily composed of macrophages, T cells, and other immune cells that surround and attempt to isolate the Mycobacterium tuberculosis.

Note that the purpose of the granuloma is to prevent the spread of the bacteria by creating a barrier, although the bacteria can remain dormant within the granuloma.

Consider that over time, the center of the granuloma may undergo necrosis, leading to the formation of scar tissue, which is a characteristic feature of TB granulomas.
