p35 (GRA8), a 35 kDa protein, has been described as a marker of acute infection able to differentiate acute from chronic infection. There are three secretory organs present in Toxoplasma gondii cytoplasm, as the dense granules. Dense granule antigens (GRA), secreted in abundance are highly immunodominant and induce strong antibody response.
