[Anti-toxoplasma antibody titers and immunoglobulins]

285 sera from parturient patients have been tested for the presence of anti-toxoplasma antibodies by the direct Agglutination test and for Immunoglobulins by the immunochemical turbidimetric determination. 17 sera showed a significant increase in the titre of anti-toxoplasma antibodies; 5 of these 17 presented a simultaneous IgM level increase, subsequently confirmed by a 2 Mercaptoethanol pretreatment, this fact suggesting the presence of active infectious disease. The authors think it can be useful in the diagnostic assessment of active toxoplasmic infectious disease the simultaneous screening of sera by the two described methods: the direct Agglutination test and the immunochemical turbidimetric determination.
