TODOROV (1970) Found that although good sensitivity was obtained with the IDT (86. 6%) in studies in Romania, the nonspecific response of 14. 5% reduced the diagnostic value of the test. RAMIREZ, MACAYA, ROJAS, SCOZIA, SCHENONE, RODRIGUEZ, DIAZ, HESS (1971) Using and IDT antigen of 20 g N/ml and a reading of 1, 6 cm^ or greater at 30 minutes as a positive test, found the technique to be useful in a survey made in Chile. WILLIAMS, PEREZ ESANDI (1971) Using passive cutaneous anaphylaxis (PCA), examined the sera of 20 dogs infected with E. granulosus for homocytotropic antibody. Five of 20 sera were positive. JEZEK, RUSINKO, MINGIR, CERENSHIMID (1971) Using an antigen preferred in Germany, conducted a survey in Mongolia. The prevalence of positive reactions was 1.4% in urban areas and 2.2% in rural areas. WILLIAMS (1972) Evaluated diagnostic sensitivity and specificity for antigen of low N content derived from sheep hydatid cyst fluid. Boiling of the hydatid fluid produced an IDT antigen with one immunologically reactive component. An antigen containing 15 g/N/ml gave a sensitivity of 80%. KAHN, SPRUANCE, HARBOTTLE, CANNON, SCHULTZ (1972) Conducted a skin test survey of 399 individuals in Herriman, Utah, which revealed five positive reactors. These individuals had negative serologic tests (IHA and BF). SCHANTZ (1973a) Demonstrated homologous skin-sensitizing antibody in serum of 6 sheep by PRAUSNITZKÜSTNER (PK) and passive cutaneous anaphylaxis (PCA) reactions. SCHANTZ, WILLIAMS, POSSE (19 73) Screened 1 669 persons in Rio Negro Province in Argentina by IDT; 8. 3% were positive. Of the 49 positive, only 13 were positive in IHA, LA, or IEP tests. LASS, LAVER, LENGY (1973) Studied IDT in 28 patients before surgical intervention. The immediate reaction was 89% reactive and 15% nonspecific. The delayed response was 68% reactive and completely specific. Evaluating IHA, IF, LA, and CF tests with a group of patients after surgery, the only test that reverted to negative in 12 months was the CFT. The CFT was, however, quite insensitive. CHENITI, HALFON, GHARBI, JEGUERIM, BEN SALAH, BEN RACHID, MOYROUD (1973) Working in Tunis, studied pulmonary hydatid cysts by ID, IHA, and IEP tests. In 43 cases tested by IDT, 25 (58%) were positive. Twenty-nine (55%) of 52 lung cysts tested by IHAT were positive and 61 (50%) of 121 lung cysts tested by IEP were positive. KAGAN, KLOCK, SPRUANCE (1974) Carried out ID and serologic tests in a small endemic area in Alaska and Utah. In Alaska the IDT was more reactive than serologic tests; the reverse was true in Utah. VARELA-DIAZ, COLTORTI (1974b) Consider the IDT unsuitable for the immunodiagnosis of hydatid disease because of the high rate of nonspecific response. ROMBERT, FRAGA de AZEVEDO (1974) Reported good sensitivity in the diagnosis of hydatid infections with passive cutaneous anaphylaxis (PCA). GARCIA ALVAREZ, REVERTE CEJUDO, HERRUZO, PEREZ PENA (1974) Compared the IDT with the CFT in 60 proven cases. In 57 tested by IDT, 39 (68.4%) were positive, and in 24 tested by CFT, only 2 were positive (8%). LOPEZ-LEMES, GUISANTES, TORRES, JOSEF (1975) Correlated the IDT with the IEP test. The sensitivity of the IEP was 74%; and that of the IDT, 54%. The authors do not recommend the IDT for diagnosis. SCHANTZ, ORTIZ-VALQUI, LUMBRERAS (1975) With a partially purified antigen prepared by boiling hydatid cyst fluid, found a high rate of nonspecific responses in a Peruvian population.
