Experimental toxoplasmic retinochoroiditis.

The technique of suprachoroidal space injection was utilized to produce experimental toxoplasmic retinochoroiditic lesions in rabbits. The lesion produced by the injection of the Beverley strain of Toxoplasma gondii closely resembled the naturally occurring disease in man, but it was less exudative and regressed spontaneously after only two to three weeks of activity. This experimental model may prove to be of use in studying pathogenetic mechanisms and therapy in this disease.
