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 the nature of tuberculosis (TB) as a bacterial infection caused by Mycobacterium tuberculosis, which primarily affects the lungs.

Recognize that a granuloma is a structure formed during inflammation, typically as a response to infection, where immune cells aggregate to contain the pathogen.

Identify the key characteristic of a TB granuloma: it is a large mass of immune cells, including macrophages, T cells, and other immune components, surrounding the Mycobacterium tuberculosis to prevent its spread.

Consider the role of scar tissue in TB granulomas, which forms as part of the body's attempt to isolate and contain the infection, leading to a fibrotic response.

Evaluate the healing process in TB granulomas, where tissue growth may occur as the body attempts to repair damage caused by the infection, but the primary function of the granuloma is containment of the bacteria.
