Toxoplasma-SPECIFIC IgG SUBCLASS ANTIBODY RESPONSE IN CEREBROSPINAL FLUID SAMPLES FROM PATIENTS WITH CEREBRAL TOXOPLASMOSIS

Cerebral toxoplasmosis can be highly debilitating and occasionally fatal in persons with immune system deficiencies.

Sumario:Cerebral toxoplasmosis can be highly debilitating and occasionally fatal in persons with immune system deficiencies. In this study, we evaluated the Toxoplasma gondii-specific IgG subclass antibody response in 19 cerebrospinal fluid (CSF) samples from patients with cerebral toxoplasmosis who had a positive IgG anti-T. gondiiELISA standardized with a cyst antigen preparation. There were no significant differences between the rates of positivity and the antibody concentrations (arithmetic means of the ELISA absorbances, MEA) for IgG(1) and IgG(2), but the rates of positivity and MEA values for these two IgG subclasses were significantly higher than those for IgG(3) and IgG(4). The marked IgG(2) response in CSF from patients with cerebral toxoplasmosis merits further investigation.
