Toxoplasmosis is the term for infection and disease in man and animal caused by a parasite called Toxoplasma gondii. The more susceptible to infect with toxoplasmosis is the Diabetic patients, due to low level of immunity response. The aim of current study is to investigate the immune status of diabetes mellitus type 2. One hundred and seventy five samples of both diabetes mellitus type 2patients and controls which had been tested by ELISA technique to detect anti-Toxoplasma Abs (IgG and IgM). The positive toxoplasmosis samples were tested to detect the level of TNF alpha and MIG. Results for all samples clarified that seronegative for IgM antibodies while 53 (53%) diabetic patients were seropositive for IgG antibodies and for toxoplasmosis only patients were 30 (40%) and 45 healthy as a (controls) were seronegative for IgG antibodies and diabetic with highly significant differences (P. value 0.0001). Serum level of TNF alpha was recorded an increase in a group of diabetic with toxoplasmosis patients (84.93 ±18.33 pg/ml) with highly differences of significant (P < 0.004) also MIG level was increased in a group of Toxoplasma gondii only (14.439 ±18.930 pg/ml) with no significant differences.
