#9300 Echinococcus multilocularis (Em2-Em18) IgG ELISA
ELISA kit for the diagnosis of human alveolar echinococcosis
(screening)
Parasitology and clinical relevance
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.
Test-Kit
96 determinations of IgG antibodies using standard methodologies.
Wells sensitized with affinity purified and recombinant antigens
(Em2-Em18) from Echinococcus multilocularis.
8-well polystyrene breakable strips : useful and economic format for
laboratories with a small workload.
