Background: The complement system consists of more than 30 proteins that are either present as soluble proteins in the blood or present as membrane-associated proteins. Inappropriate complement activation and complement deficiencies are the underlying cause of the pathophysiology of many diseases. Methods: A case-control study was conducted to asses role of complement system during toxoplasmosis in Najaf province. Thirty five sera of infected women with toxoplasmosis by investigation antibody against toxoplasmosis for IgG and IgM by ELISA technique were tested to determine the levels of C3 and C4 by using single radial immunodiffusion technique and compared with the ten of control sera of non infected subjects and non-aborted. Results: The high C3 in significant differences(P<0.05) and C4 with no significant differences(P>0.05) levels were found in aborted toxo-positive women in compared with control. Likewise, it was found that association between concentration of C3,C4 and number of abortion. Conclusion: complement were play role in immune response of pregnant women especially against toxoplasmosis that cause abortion to these women.
