Genes encoding _____ rearrange in trypanosomes permitting replication and survival of the pathogen until the host produces an antibody response against the altered gene product.

Question

Quizplus · Accepted Answer

The genes encoding variable surface glycoproteins (VSGs) rearrange in trypanosomes allowing for the pathogen to evade the host's immune response. As the host begins to produce antibodies against a specific VSG, the parasite switches to a different VSG, allowing for continued replication and survival. Pilin and flagellin are proteins involved in bacterial motility and not present in trypanosomes. Hemagglutinin is a protein found in some viruses and not present in trypanosomes.
