摘要

Echinococcus multiloculoris is a zoonotic tapeworm that occurs in central Europe, much of northern, central and eastern Eurasia, and parts of North America1. Adult parasites reside within the small intestine of definitive hosts, which are primarily wild canids (e.g. foxes, coyotes, wolves). However, in some areas, domestic dogs, and to a lesser extent cats, may act as definitive hosts. Eggs shed in the feces of these species are morphologically indistinguishable from foen/o-type eggs and are immediately infective for intermediate hosts which include various species of wild rodents2. Subsequent to ingestion, a hexacanth embryo is released from the egg, travels to the liver via the hepatic portal circulation and develops into alveolar hydatid cysts1.This larval stage of the parasite is comprised of numerous small vesicles lined with a germinal epithelium from which multiple protoscolices develop, undergoes exogenous budding, and behaves like an invasive tumour1. The resultant disease, alveolar echinococcosis (AE), is associated with extensive damage to the liver and occasionally spread to other locations within the intermediate host. When an infected intermediate host is ingested by a definitive host the life cycle is completed; development to themature tapeworm takes approximately 4-5 weeks3. Lastly, ingestion of eggs by people may also result in AE, a potentially severe, fatal disease that is currently an emerging issue in parts of central Europe.
