| Abstract: | Twelve Taenia solium cysticerci, obtained from several human organs, were examined by immunofluorescence for IgG, IgM, IgA, IgE and C3b on their surfaces. Anti-cysticercus antibodies of the 4 classes of immunoglobulins were looked for in the cerebrospinal fluid of most neurologic patients, in the intraocular humors of a patient with eye cysticercosis, and in the serum of some other patients. The morphological appearance of the parasites as well as the clinical features of the patients were recorded. The distribution of components was heterogeneous among the different parasite surfaces. IgG was the most frequent, followed by IgA, IgM, C3b and IgE. No correlation was found between the presence of these molecules and signs of damage in the cysticerci, or with the classes of immunoglobulins found as anti-cysticercus antibodies. Possible explanations of these findings as well as the implications of heterogeneity in cysticercosis are discussed. |
