Which parasitic protist evades the host immune system by altering its surface proteins with each generation?
paramecium caudatum
trypanosoma brucei
plasmodium falciparum
phytophthora infestans

Trypanosoma brucei

Explanation:

T. brucei is a unicellular eukaryotic parasite that causes sleeping sickness. This organism has an elongated body, central nucleus, only an elongated mitochondria housing the kinetoplast, where the mitochondrial DNA is located; It has a scourge that gives it motility. Its undulating cell membrane, as a result of flagellar movements, is covered with glycoproteins that elicit little immune reaction, allowing this parasite to go unnoticed.

This organism infects the host by evading the host's immune system by altering its surface proteins with each generation.
