Evaluation of whole and purified hydatid fluid antigens in the diagnosis of human hydatidosis by the immunoelectrophoresis test. 1975

Whole sheep hydatid cyst fluid (WHF) and purified hydatid fluid antigens (PHF) were evaluated in the immunoelectrophoresis (IEP) test for the diagnosis of human hydatid disease. A higher sensitivity was obtained using the PHF than with the WHF antigen but false positive results were observed with the former in 22.4% of the 102 non-hydatid sera examined. Using the presence of arc 5 as the criterion of positivity however, no false positives were observed in non-hydatid sera with the WHF antigen. It is postulated that the number of bands other than arc 5 may be of value in the diagnosis of hydatid disease by the IEP test, in cases where this diagnostic arc is absent.

UI MeSH Term Description Entries
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D010272 Parasitic Diseases Infections or infestations with PARASITES. They are often contracted through contact with an intermediate vector, but may occur as the result of direct exposure.

D004443 Echinococcosis An infection caused by the infestation of the larval form of tapeworms of the genus Echinococcus. The liver, lungs, and kidney are the most common areas of infestation.

D004446 Echinococcus A genus of very small TAPEWORMS, in the family Taeniidae. The adult form is found in various CARNIVORA but not humans. The larval form is seen in humans under certain epidemiologic circumstances.
