Serological Survey of Antibodies to Toxoplasma Gondii in Sheep in NorthWest of Iran

Objective: Sera from 186 sheep (93 rams and 93ewes) from Tabriz, NorthWest of Iran were evaluated for antibodies to Toxoplasma gondii using a commercial ELISA kit. Methods: The animals were divided into two age groups ( lt; 2 years, and gt; 2 years). Results: Antibodies to T. gondii were found in 13 of 186 sheep (6.98%). Infection rate in ewes was higher than rams but this difference was not significant. The seroprevalence of Toxoplasma in sheep gt;2 years old was significantly higher than in other age groups. Conclusions: Results of this study indicate a low prevalence of T. gondii in sheep tested in Tabriz by ELISA.
