Abstract
The capacity of Toxoplasma gondii surface protein SAG2 to induce protective immunity against the parasite in mice was studied using recombinant SAG2 expressed as a glutathione-S-transferase (GST) fusion protein incorporated into immune stimulating complexes (iscoms). Immunization with the iscoms resulted in the production of antibodies recognizing SAG2 as well as GST. After oral challenge infection with T. gondii oocysts or tissue cysts, no protective effect was observed. On the contrary, mice immunized with fusion SAG2 or with GST iscoms died earlier than non-immunized control mice.
