Detection of Toxoplasmosis gondii seropositivity in sheep in Yalova by Sabin Feldman Dye Test and Latex Agglutination Test.

Abstract

Sera collected from 63 sheep older than one year of age in two regions of Yalova were tested for anti- Toxoplasma gondii antibodies using the Sabin-Feldman Dye Test (SFDT) and Latex Agglutination Test (LAT). Of the 63 samples tested, 42 (66.66%) and 41 (65.08 %) were determined to be seropositive by SFDT and by LAT, respectively. Of the positive sheep serum samples, 23 were positive at a dilution of 1/16; 13, at a dilution of 1/64; and 6, at a dilution of 1/256. SFDT was accepted as a reference test. The sensitivity and specificity of LAT were 78.57% and 61.90 %, respectively. The correlation between these two tests was determined to be 73.01%.
