The aim of this study is to increase our alertness and monitoring in case of toxoplasmosis during pregnancy, given that when diagnosed it can be effectively treated.We present a case of a healthy 26 years old adult woman, found with toxoplasmosis during the 13th week of pregnancy. The role of frequent maternal and fetus immunological tests, PCR-tests of the amniotic fluid and ultrasound screening of the fetus throughout pregnancy was of great value. The patient was treated with spiramycin (1 grx3) from the 16th week of pregnancy. The patient was subjected to cesarean delivery at the 36th week of pregnancy due to preterm contractions and history of previous cesarean delivery. The newborn was a healthy girl with a birth weight of 2880 gr. A two-year follow up of the baby revealed no medical condition. Maternal infections are a serious medical condition during pregnancy. Toxoplasmosis when diagnosed on time and treated properly can lead to healthy offspring.
