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), antioxidant capacity (TAC) and index (OSI) in sheep naturally infected with Toxoplasma gondii (T. gondii). A of 30 Morkaraman breed were used this study. Blood samples obtained from 10 healthy control 20 T. gondii. malondial- dehyde, GSH, TOS TAC levels determined serum samples. The ratio assessed OSI. While the MDA level increased significantly (P<0.01), de- creased (P<0.01) sheep. There no different for GSH OSI between groups (P˃0.05). Negative correlation a positive In conclusion, results suggested that OSI, could be indicator
