Stage-specific expression of surface antigens by Toxoplasma gondii as a mechanism to facilitate parasite persistence.

Abstract excerpt

Toxoplasma persists in the face of a functional immune system. This success critically depends on the ability of parasites to activate a strong adaptive immune response during acute infection with tachyzoites that eliminates most of the parasites and to undergo stage conversion to bradyzoites that encyst and persist predominantly in the brain. A dramatic change in antigenic composition occurs during stage...
