Cysticerci of Taenia solium cause cysticercosis, with neurocysticercosis (NCC) as the major pathology. Sensible and specific recombinant antigens would be an source of antigen for immunodiagnosis. The objective of this work was the molecular characterization and evaluation, of three news recombinant antigens (TsF78, TsP43 and TsC28), obtained by screening of a Taenia solium cDNA library. The three cDNA were analysed by bioinformatic programs, subcloned and expresed. The purified proteins were evaluated in ELISA using cyst fluid as control. TsF78 is filamina, TsP43 a peroxidase and TsC28 collagen XV. The sensitivity and specificity of the recombinant proteins were; TsF78 93.8 % and 95.0 %, TsP62 91.7 % and 93.3 %, TsC28 85.4 % and 93.3 %, respectively, while the cyst fluid showed a sensitivity of 87.5 % and a specificity of 76.7 %. Given its high sensitivity and specificity, the recombinant proteins TsF78 and TsP62 could be used in the diagnosis of cysticercosis.

D003551 Cysticercosis Infection with CYSTICERCUS, the larval form of the various tapeworms of the genus Taenia (usually T. solium in man). In humans they penetrate the intestinal wall and invade subcutaneous tissue, brain, eye, muscle, heart, liver, lung, and peritoneum. Brain involvement results in NEUROCYSTICERCOSIS.
