The classical diagnosis of toxoplasmosis relies on serological methods. Detection of parasite or its components could be useful tool for early diag­nosis of the infection. Methods: Fifty mice were infected by the intraperitoneal route with 5000 tachyzoites of T. gondii RH strain. Five of them sacrificed every day from day 1 up to day 7 post infection. Sera and urine of mice were tested by capture ELISA. Results: T.gondii antigens were detected from 3rd and 2nd day in serum and urine, respectively, after infection until their death on day 7. Conclusion: Antigenemia detection of antigens of parasite was possible in a short period of acute infection with T. gondii by capture ELISA. https://ijpa.tums.ac.ir/index.php/ijpa/article/view/44 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/44/43
