title: [Seroepidemiological investigation of various tissue helminthiasis, by means of indirect hemagglutination test, in Lonquimay County, Chile].
abstract: In order to have a present perspective on the prevalence on the epidemiology of some tissue helminthiasis in Lonquimay County, southern Chile, in 1993 a seroepidemiological survey, by means of an indirect hemagglutination test (IHAT) for hydatidosis, cysticercosis and trichinosis was undertaken. In 11 (1.2%), 10 (1.1%) and 6 (0.6%) out of 945 examined persons, most of them from rural areas, the corresponding IHAT resulted positive. Additionally, radiographic and ecotomographical studies for thorax and abdomen respectively were performed to the 11 individuals with serology positive for hydatidosis: whereas all the thoracic radiographies resulted negative, liver hydatic cysts were detected in five persons, who latter on were submitted to surgery. Prevalence rates of hydatidosis in Lonquimay are among the highest regional and national values.
