Summary This Study was conducted to compare efficacy of latex agglutination test (LAT) and indirect enzyme linked immunosorbent assay (iELISA) in determination of Toxoplasma gondii seroprevalence in dairy cattle in Khartoum and Gezira States. Blood samples were collected from 181 dairy cattle in the two states and serologically examined to determine the two tests concordance. Seroprevalence of T. gondii at the herd level was 44.8% (13/29) using both LAT and iELISA. The infection rates at the herd level in Khartoum State was 50% whereas 33.3% in Gezira State. The overall seroprevalence of T. gondii at the individual level in both states attained 13.30% (24/181) and 21.5% (39/181) using iELISA and LAT, respectively. However, analysis of the obtained results revealed that the two serological tests had 93% (27/29; Kappa 0.86) and 70% (126/181; Kappa -0.048) concordance at the herd and individual levels, respectively. In conclusion, the results herein reported suggest that LAT is a simple and reliable test for quick screening of toxoplasmosis in dairy cattle at the herd level but not at the individual level.
