Evaluation of Immunohistochemistry and PCR in Diagnosis of Toxoplasma Infection in Tissues of Human Aborted Fetuses

T oxoplasma gondii is one of the most common protozoa that infect humans and a wide range of mammalians and birds [1]. The infection is particularly important in women when they acquire the infection for the first time during their pregnancy where an intrauterine transmission of the parasite may occur. Effective prenatal diagnosis of congenital toxoplasmosis can permit a decision to terminate the pregnancy at the early stage or initiate the treatment of late-term fetus in uterus. Prenatal diagnosis is commonly performed based on biological and serological tests on fetal blood and amniotic fluid, and ultrasonographic examination of fetus [2].
