Detection of toxoplasmal antigen and antibody in ocular fluids in experimental ocular toxoplasmosis.
Enzyme-linked immunosorbent assays were used to detect intraocular toxoplasmal antigen and antitoxoplasmal IgG antibodies in a rabbit model of experimental ocular toxoplasmosis. Toxoplasmal antigen could be detected in the vitreous humor of the infected eye at the height of clinical activity of the lesion. Antitoxoplasmal IgG antibodies were detected in the aqueous and vitreous humors of the infected eyes five weeks following the onset of toxoplasmic retinochoroiditis.
