Objective: The current research study was completed in some areas of Kirkuk Governorate, where samples were collected randomly from pregnant women who had miscarriages arriving at government hospitals and some private medical clinics, whose ages ranged between 18-35 years for a period from 25/3/2024 to 1/10/2024. Methode: 150 samples were collected from pregnant women who had miscarriages (first miscarriage). It was suspected that they were infected with Toxoplasma, and a rapid test was performed to detect IgM and IgG, as 60 samples were confirmed to be infected with the Toxoplasma parasite through the appearance of a positive IgG result, and 30 uninfected samples were IgM negative. After that, blood was taken from patients and healthy and separated using a centrifuge. Then the intrelukin-17-IL-17, Chemerin, and some biochemical variables such as thyroid hormones (T3, T4, TSH), and antioxidants including glutathione peroxidase -GPX, Superoxide dismutase -SOD and Copper-Cu were measuring. Result: The results of this study showed a significant rise in each parameter (IL-17, chemerin, T3, T4, TSH, and Cu) and a significant low in concentration of (GPX, SOD) in the sera of women infected with T.gondii compared to healthy women, with a probability of P ≤ 0.05.
