title: Determination of diagnostic value of Toxoplasma gondii recombinant ROP2 and ROP4 antigens in mouse experimental model.
abstract: The aim of this study was to test the potential diagnostic usefulness of recombinant Toxoplasma gondii rhoptry antigens, ROP2 and ROP4, with respect to toxoplasmosis detection and infection phase distinction in laboratory mouce by determining specific serum IgM and IgG antibodies with the use of indirect ELISA technique. The mice antibody response to ROP antigens was significantly higher in the IgM than in the IgG class with the peak on the turn of acute and latent infection, whereas the response to recombinant SAG1 antigen, used as control, revealed preferential synthesis of IgG antibodies with the highest absorbance values measured during latent toxoplasmosis.
