The humoral response to the cruzipain antigen, the largest antigen of Trypanosoma cruzi, is implicated in the pathogenesis of experimental Chagas disease.

D. Borrelia burgdorferi changes its surface antigens to avoid immune recognition

Borrelia burgdorferi is a bacterium that produces Lyme disease, once infected, the bacterium recombines by altering the antigens of its membrane, preventing immune recognition.
