Abstract: 　Objective] To understand the concurrent in Toxoplasma infection among women with cervical cancer. [Methods] The anti Toxoplasma IgG, IgM antibodies (Abs) and circulating antigens (CAg) in 247 sera ( from 50 cases with cervical cancer in group 1, 59 cases with gynaecological benign tumors in group 2 and 138 cases with other diseases in group 3 ) were detected by ELISA. [Results] The total positive rates of the CAg and the Abs in the three groups were 44 0% (22/50), 25 4% (15/59) and 20 3% (28/138), respectively. The positive rates were 20 0%, 11 9% and 10 9%, respectively for IgG 20 0%, 13 6% and 8 7%, respectively fot IgM and 14 0%, 5 1% and 1 4% respectively for CAg. [Conclusion] The Toxoplasma infection rate of the cervical cancer group was higher than those of the other two groups, particularly the positive rates of CAg and IgM.

Key words: Toxoplasma infection, cervical neoplasms, ELISA, circulating antigen, IgM, IgG.
