Immunoelectrophoresis (IEP), double diffusion (DD5), indirect hemagglutination (IHA), and intradermal (ID) tests were evaluated to determine their ability to detect echinococcosis in sheep. Four sheep were infected per os with approximately 4,00, 1-wk-old eggs of Echinococcus gradulosus; four more sheep were similarly infected with approximately 3,000 1-wk-old eggs of Taenia hydatigena, and two additional sheep were used as uninfected controls. Blood samples were collected from each sheep prior to infection, at 2 and 4 wk postinoculation, and monthly thereafter for 1 yr. Serum from each blood sample was tested by IEP and DD5 for antiantigen "5" activity and by IHA for Echinococcus-specific hemagglutination activity. Following the last blood collection, an ID test for echinococcosis was performed on each sheep, after which all sheep were necropsied, and the type, location, and size of all larval tapeworms recorded. The DD5 test was found to be more sensitive and at least as specific as IEP in detecting echinococcosis in sheep. The IHA test approached the specificity and sensitivity pattern of DD5 and IEP if a titer of greater than or equal to 1:1,024 was considered positive. The ID test supported DD5 and IEP results but demonstrated a lack of specifiity. Necropsy data verified that all sheep were infected according to the experimental design. We conclude that DD5 reliably detects echinococcosis in experimentally infected sheep, and that further research is warranted to evaluate this test for detecting echinococcosis in naturally infected sheep.
