[Clinical course of congenital toxoplasmosis in dicygotic twins (author's transl)].

The presented case report deals with the clinical course of a congenital toxoplasmosis in dicygotic twins. The variability of the clinical course was proofed, because one of the twins remained unaffected with clinical signs and was detected only by the conversion of the seroreactions. On the other hand the second twin showed the picture of an acute meningoencephalitis resulting in a neurological defect syndrome. The reasons for the different clinical course, which is more pronounced in dicygotic twins than monocygotic, remain unknown.
