Pregnant women, also without symptoms, may transmit the infection to the foetus, which can result in abortion, still-birth, perinatal death (due to disseminated toxoplasmosis), or congenital infection with severe malformation affecting the eyes and the brain.
Nosečnice, ki so prav tako brez simptomov, lahko prenesejo okužbo na plod, kar ima lahko za posledico splav, mrtvorojenost, perinatalno smrt (zaradi razsejane toksoplazmoze) ali kongenitalno okužbo s hudo deformacijo, ki prizadene oči in možgane.
