Question

Which of these is an example of an opportunistic disease-causing protozoan in AIDS patients?
A)Plasmodium vivax
B)Trypanosoma brucei
C)Giardia lamblia
D)Entamoeba histolytica
E)Toxoplasma gondii

Accepted Answer

Toxoplasma gondii is an opportunistic protozoan that can cause disease in AIDS patients. It can cause toxoplasmosis, which primarily affects the brain and can lead to seizures, confusion, and other neurological symptoms. Plasmodium vivax and Trypanosoma brucei are parasites that cause malaria and African sleeping sickness, respectively, but they are not typically opportunistic in HIV patients. Giardia lamblia and Entamoeba histolytica can cause gastrointestinal infections but are not commonly associated with opportunistic disease in AIDS patients.
