One hundred and seven cases, 35 males and 72 females aging from 3 months to 32 years old were divided into 4 groups: ocular, neurological, cases with abortion and cases having Down's syndrome. 47 apparently healthy individuals were taken as control. All were serologically tested for Toxoplasma antibodies using IFAT and ELSA for detection of IgG. The positive cases as well as cases below one year old were tested by ELISA IgM for the detection of acute or congenital toxoplasmosis. Toxoplasma antibodies (IgG) were found in 28 (26%) and 43 cases (40%) by IFAT and ELISA respectively. ELISA IgM was positive in 12 (20%) out of 60 serum samples. Two cases (11%) among 27 patients below one year old positive. Statistical significance was reported concerning the positive cases in the ocular group as well as patients with abortions. Results revealed that ELISA is more sensitive and specific than IFAT.
