This study was conducted to determine seroprevalence of Toxoplasma gondii in sheep in Malatya and its vicinity. Blood samples were collected from a total of 220 sheep at various ages and breeds. Among these sheep, 71 were 0-12 months old and 149 were older than one year. Sera obtained from these blood samples were examined by Sabin-Feldman (SF) test to detect Toxoplasma gondii antibodies.

Toxoplasma gondii infection was determined in 73 (33.2%) of 220 sheep at the titers ranging from 1/16 to 1/1024. In this test, 2.8% of 0-12 months old lambs and 47.7% of sheep older than one year were found to be positive.
