INTRODUCTION Echinococcosis or hydatidosis is a zoonosis caused by cestodes from the genus Echinococcus; its habitat is the small intestine of the definitive host, represented by dogs/carnivorous animals, where it produces eggs which are eliminated in the environment. Cystic echinococcosis represents more than 95% of the hydatidosis cases registered annually. The most frequent localization is t...

A 6-year retrospective study based on abattoir records was carried out to determine the prevalence of hydatidosis in dromedaries in Khorasan province in north-eastern Iran. Between 20 March 2004 and 19 March 2010, 25,255 dromedaries were slaughtered in the study area and the livers of 2791 (11.1%) and the lungs of 3289 dromedaries (13.2%) were discarded due to hydatidosis. The annual prevalence...

To further assess the double diffusion arc 5 (DD5) test for human hydatidosis, the test was performed on sera from 45 patients with surgically confirmed hydatidosis and 54 with other pathologies in Santiago, Chile. Combined with tests reported previously, this brought the total number of study subjects with confirmed hydatidosis to 98 and the total with other pathologies to 128. Overall, the te...

Secondary peritoneal hydatidosis is caused by spontaneous or iatrogenic rupture of hepatic echinococcal cysts. We describe the case of a 65-year-old Tunisian male patient with previous history of liver hydatidosis who presented to our attention with subocclusive status. Imaging revealed a retrovesical hydatid cyst, adherent to the sigmoid colon. The treatment of choice was surgical removal of t...
