Determination of seropositivity for Toxoplasma gondii in sheep in Sanliurfa province

The aim of this study was to detect the seropositivity for Toxoplasma gondii in sheep in Sanliurfa province using the Sabin-Feldman dye test. Serum samples collected from 300 sheep were tested for T. gondii. Serological examination revealed 167 (55.66%) sheep to be seropositive. Among these sera the numbers of seropositive samples at certain dilution steps were as follows: 65 at 1/16. 63 at 1/64, 27 at 1/256 and 12 at 1/1024. There was no significant correlation between seropositivity and the factors age, sex and breed. In conclusion, detection of a 34% seropositivity rate in 1/64 and higher dilutions indicates the clinical course of toxoplasmosis in the region.
