9300 Echinococcus multilocularis

#9300 Echinococcus multilocularis (Em2-Em18) IgG ELISA
ELISA kit for the diagnosis of human alveolar echinococcosis (screening)

Alveolar echinococcosis is caused by an infection with the cestode Echinococcus multilocularis and is a very dangerous disease for humans. Adult worms mature in the intestine of the definitive host (usually fox, occasionally dog or cat) and the eggs are released in the feces. Accidental ingestion of soil, berries or vegetables contaminated with eggs iniate the infection in humans. Oncospheres hatch in the duodenum, penetrate the intestine and are carried via the bloodstream to organs. Although alveolar hydatid cysts have been found in other tissues, the most common site of development is the liver. The cysts are not limited by a membrane but penetrate the tissues and may resemble a slow growing carcinoma. Surgical removing is difficult but drugs have been found that stop the development of the metacestode. Medical imaging and serology give both useful and complementary information on the nature of the cyst and on the outcome of treatment.
