RESUMEN
Cysticercus cellulosae extract (CS), cyst fluid (CF), and an extract of Taenia saginata adult worm (TS) were evaluated for use in an enzyme-linked immunosorbent assay (ELISA) for serodiagnosis of human neurocysticercosis in Thai patients. ELISA sensitivity was found to be 78.13%, 81.25% and 62.50%, respectively. False positivity was 6.66% with CS and 0% with other antigens. CF gave positivity with a pooled visceral gnathostomiasis serum and 3 of 10 (30%) of angiostrongyliasis sera. CS produced weakly positive ELISA with pooled opisthorchiasis and visceral gnathostomiasis sera. TS gave weak positive ELISA with a pooled opisthorchiasis serum. It was concluded that CF was the best antigen for use in ELISA for serodiagnosis of human neurocysticercosis.
