| echinococcus | <dermatology, microbiology> A tissue infection by the larval stage of the Echinococcus granulosus worm. This disease is common in South America, the Middle East, Asia and Africa. Sporadic cases have been reported in the us. Infection occurs after ingestion of eggs in infected dog faeces. The infection is carried to the liver where cysts form. Cysts may also form in the lungs, bone, brain, kidney, muscles and spleen. Symptoms include abdominal pain, itching, cough, haemoptysis, chest pain and fever. Treatment includes the surgical removal of cysts from the tissue. (19 Jan 1998) |
| echinococcus cyst | A cyst formed in the liver, or, less frequently, elsewhere, by the larval stage of Echinococcus, chiefly in ruminants; two morphological forms caused by Echinococcus granulosus are found in humans: the unilocular hydatid cyst and the osseous hydatid cyst; a third form in humans is the alveolar hydatid cyst, caused by Echinococcus multilocularis. Synonym: echinococcus cyst, hydatid. (05 Mar 2000) |
| echinococcus disease | Infection caused by tapeworms of the genus echinococcus. The larval stage is called hydatid or hydatid cyst and develops in almost all mammals, especially domestic and farm animals, and in man under certain epidemiological conditions. The liver, lungs, and kidney are particularly common sites of development and infestation. . Echinococcosis, hepatic and echinococcosis, pulmonary are also available. (12 Dec 1998) |
