Aim:
To explore an assay method for the early diagnosis of Toxoplasma infection.
Methods:
Serum samples collected from three groups of mice infected experimentally with different doses of Toxoplasma trophozoites were detected for the presence of Toxoplasma circulating antigen by using fast ELISA.
Results:
Toxoplasma circulating antigen was detected on days 4, 4 and 3 after infection in light, moderate and heavy infection groups, respectively.
Conclusion:
The level of circulating antigen was in parallel with the duration of infection. The determination of circulating antigen is useful in the early diagnosis of Toxoplasma infection.
