**Core Concept**
Infections of red blood cells can be caused by various pathogens, including bacteria, viruses, and parasites. This phenomenon is known as "multiple infection" or "polyinfestation" of red blood cells.

**Why the Correct Answer is Right**
The correct answer is a type of parasite that can infect red blood cells, leading to a condition known as malaria. Plasmodium species, such as Plasmodium falciparum, can invade and multiply within red blood cells, causing the cells to become enlarged and fragile. This can lead to a range of clinical symptoms, including fever, anemia, and organ failure.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a type of bacteria that can cause a different type of infection, such as tuberculosis. Mycobacterium tuberculosis primarily infects the lungs and other tissues, but it does not typically infect red blood cells.

**Option B:** This option is incorrect because it is a type of virus that can cause a range of infections, including mononucleosis and hepatitis. Epstein-Barr virus and hepatitis B virus can infect various cells in the body, but they do not typically infect red blood cells.

**Option C:** This option is incorrect because it is a type of fungus that can cause a range of infections, including candidiasis. Candida species can infect various tissues and organs, but they do not typically infect red blood cells.

**Clinical Pearl / High-Yield Fact**
Malaria caused by Plasmodium falciparum can lead to a severe form of the disease known as cerebral malaria, which can cause seizures, coma, and death if left untreated. This highlights the importance of prompt diagnosis and treatment of malaria to prevent serious complications.

**Correct Answer:** D.
