title: Bovine cysticercosis: demonstration in experimentally infected calves of serum IgG antibodies reactive with neutral glycolipids of Taenia saginata and T. crassiceps metacestodes.
abstract: The immunoreactivity of Taenia saginata and T. crassiceps metacestode neutral glyco(sphingo)lipids towards IgG antibodies derived from the sera of calves with experimental cysticercosis has been established. The glyco(sphingo)lipids are separable by normal-phase HPTLC (high-performance thin-layer chromatography) into groups of increasing sugar-chain length (lipid/ceramide mono-, di-, tri-, tetra- and > tetrasaccharides), with those corresponding to three and four hexoses being the main immunoreactive components (HPTLC immunostaining). In ELISA (enzyme-linked immunosorbent assay), reverse-phase HPTLC-isolated T. crassiceps metacestode glyco(sphingo)lipids equivalent to tri- and tetrahexoside allowed a discrimination between non-infected and infected calves (at least 80 metacestodes recovered). The formation of IgG antibodies was correlated with the infection, not with other non-specific inducing factors, as seen by the differential humoral response detected in experimentally infected (T. saginata) calves before and after Praziquantel treatment (HPTLC immunostaining and ELISA).
