[Evaluation of helminth intradermal tests in comparison to coproovoscopic surveys].
1600 subjects connected with mining were divided into 6 groups and examined because of intestinal parasites. There were: surface miners underground miners, retired miners and two groups of school-children up to 14 years old and from 14-17 years old, and persons not connected with the miners' work. The one control group consisted of 150 persons with negative coproscopical investigations, the other consisted of 112 persons, who were clinically healthy. The coproscopical investigations, morphological (eosinophil) and intradermal tests were made with the antigens Ascaris lumbricoides, Echinococcus granulosus, Cysticercus cellulosae, Taeniarhynchus saginatus and Trichinella spiralis. 214 persons (13.37%) were infected. The infestation with Enterobius vermicularis and Ascaris lumbricoides (about 96%) was prevailing. Eosinophily varied between 5-7% and was found in 111 persons (6.3%). Most positive intradermal tests with Ascaris lumbricoides antigen were confirmed in the group of patients infected with Ascaris lumbricoides (97%). Some cross-reactions were confirmed. The heaviest infestation with parasites was found out with the underground workers. The results of the coproscopical investigations were mostly similar to the results of the intradermal tests.
