Final answer:
Opportunistic infections associated with AIDS include Pneumocystis pneumonia, Tuberculosis, and Candidiasis. These infections exploit the weakened immune system in AIDS patients. Influenza, while common, is not considered an opportunistic infection of AIDS.
Step-by-step explanation:
Acquired immunodeficiency syndrome (AIDS) is characterized by the occurrence of opportunistic infections due to the significant impairment of the immune system caused by the human immunodeficiency virus (HIV). Among the options provided, Pneumocystis pneumonia (A), Tuberculosis (B), and Candidiasis (D) are associated with AIDS.
- Pneumocystis pneumonia is a fungal infection caused by P. jirovecii and is commonly seen in patients with severely compromised immune systems, such as those with AIDS.
- Tuberculosis, caused by the Mycobacterium tuberculosis bacteria, can be an opportunistic infection in the presence of AIDS due to the weakened state of the immune system.
- Candidiasis is an infection with the yeast Candida spp., which can occur in patients with AIDS as their weakened immune response allows for the unchecked growth of this normally controlled fungus.
Influenza (C) is a common viral infection, but it is not categorized as an opportunistic infection specifically associated with AIDS.
