Diagnosis of central nervous system infections can be

accomplished by demonstrating the presence of intrathecally-

produced specific antibody. Interpretation of results may

be complicated by low antibody levels found in CSF, passive

transfer of antibody from blood, and contamination via

bloody taps.

 

Antibodies to other parasitic infections, particularly echinococcosis,

may crossreact in the cysticercus IgG ELISA. Confirmation of positive

ELISA results by the cysticercus IgG antibody Western blot is thus

recommended.
