23 Cestodes are unable to synthesize de novo most of their own membrane lipids, including 24 cholesterol, and have to take them up from the host during an infection. The underlying 25 molecular mechanisms are so far unknown. Here we report the identification and characterization 26 of a novel gene, Emabp, which is expressed by larval stages and adults of the fox-tapeworm 27 Echinococcus multilo...

There is little information on the humoral response of sheep experimentally infected with Echinococcus granulosus. Thus, the objective of this study was to evaluate this response and measure its evolution. Doses of 10, 100, 1000 and 10000 E. granulosus eggs were prepared and inoculated via intraruminal puncture. Blood samples were obtained before inoculation and every 48 h after inoculation, un...

Pulmonary hydatid disease is a particular radiological diagnostic problem when the hydatid is small, single, and symptomless, so that distinction must be made from the numerous other causes of isolated, peripheral pulmonary lesions. The technique of delivery of a pulmonary hydatid cyst, different from the management of other single peripheral lesions, makes preoperative recognition of hydatid d...

Hydatid disease is a parasitic tapeworm infestation that usually involves liver and lungs. Primary retroperitoneal hydatid without liver and lung involvement is very rare. Surgery is the principle method of treatment for large retroperitoneal hydatid, whenever feasible. We report a case of primary retroperitoneal hydatid cyst in 29-year-old male patient.

Collapsed membranes and daughter cysts are pathognomonic for hydatid cysts on imaging. The comma-shaped lesions, visible within the hydatid cyst in sagittal view of MRI, are collapsed membranes. Although primary hydatid cyst of pelvic cavity is rare, clinicians should remember to include hydatid cysts in differential diagnosis of pelvic cysts.

A hydatid cyst is an endemic disease in our country. Clinical manifestation includes cyst formation, most commonly in the liver and lungs. Renal, brain, and subcuteneous localizations are rare. Here we report four cases: two cases of primary renal hydatid disease, one of intracranial hydatid cyst, and one of subcutaneous hydatid cyst. We discuss the prevalence, diagnostic workup, and management...

Spleen is an unusual location for hydatid cyst. Here we report a case of primary splenic hydatid cyst in a 41-yr-old Iranian woman from Yasuj, southwest of Iran. The patient had been admitted to Shahid Beheshti Hospital because of abdominal pain. Abdominal sonography revealed a hypoechoic lesion of 150 X 130 mm in the spleen, suggestive of hydatid cyst. Splenectomy was performed for the patient...

BACKGROUND One of the most common problems faced in laparoscopic treatment of hydatid cysts is the difficulty in evacuating the particulate contents (daughter cysts and laminated membrane). Although various instruments and laparoscopic techniques have been described to evacuate the contents of hydatid cysts, most are not available at many surgical centers. METHODS By assembling disposable, ch...

From 1989-1992, 35 cases comprising of 20 hepatic and 15 pulmonary hydatid cysts were seen. Four patients with pulmonary hydatid disease had previous or concomitant hepatic hydatidosis compared to no concomitant pulmonary hydatid disease in the hepatic group. Hepatic hydatid disease had a greater tendency to be right sides, infected and calcified. Anaphylactic reactions occurred in 3 of 20 pati...
