Toxoplasma gondii'li koyunlarda Oksidatif Stresin Glutatyon, Malondialdehit Düzeyi, Oksidatif Stres İndeksi, Toplam Oksidan Durumu ve Toplam Antioksidan Kapasitesi Kullanılarak Değerlendirilmesi

This study was conducted to evaluate oxidative stress using markers such as malondialdehyde (MDA), glu- tathione (GSH), total oxidant status (TOS), total antioxidant capacity (TAC) and oxidative stress index (OSI) in sheep naturally infected with Toxoplasma gondii (T. gondii). A total of 30 Morkaraman breed sheep were used in this study. Blood samples were obtained from 10 healthy control sheep and 20 sheep naturally infected with T. gondii. malondial- dehyde, GSH, TOS and TAC levels were determined in serum samples. The ratio of serum TOS to TAC levels was assessed as OSI. While the serum MDA level increased significantly (P
