Quizplus · Accepted Answer

Studies have shown that HDL, commonly known as "good cholesterol," provides protection against nagana in humans. HDL has been found to bind to a protein in the tsetse fly saliva, preventing the transmission of the parasite that causes nagana. Serum, LDL, and iron have not been identified as protective factors against nagana in humans.
