title: Detection of antibodies to Angiostrongylus cantonensis in serum and cerebrospinal fluid of patients with eosinophilic meningitis.
abstract: Adult and young adult antigens of Angiostrongylus cantonensis were purified by immuno-affinity chromatography and used to detect antibody in serum and cerebrospinal fluid (CSF), by enzyme-linked immunosorbent assay (ELISA), in cases of human eosinophilic meningitis or meningoencephalitis. The levels of IgG, IgA, IgM and IgE antibodies to A. cantonensis in these patients were higher than levels in control subjects. Antibodies in patients detected against adult and young adult worm antigens of A. cantonensis did not differ significantly. Significantly higher IgM and IgE antibody levels were observed in serum compared with CSF from infected patients (Student's t-test, P less than 0.05). Both adult and young adult A. cantonensis antigens proved to be highly sensitive in ELISA for serum antibodies; however, the sensitivity was significantly lower in tests on CSF.
