Ten animals were killed every day from day 1 up to day 7 post infection. Urine and sera of animals were collected and stored at -20 degree C until use. PCR performed by B1 gene amplification. Toxoplasma was detected in sera from 3 days post infection and in urine from 5 days post infection. No parasite was detected in control group.
