Alveolar echinococcosis (AE) is a dangerous zoonotic disease caused by the larval forms of Echinococcus multilocularis tapeworm. E. multilocularis is considered the most dangerous parasitic zoonotic agent in the Northern Hemisphere, and AE is usually fatal if left untreated. In the life cycle of this parasite, the red fox (Vulpes vulpes) plays the role of a typical definitive host (in it’ s intestines mature forms of this tapeworm develops). Rodents are a typical intermediate host where E. multilocularis larvae develop. In the life cycle, human acts as a nonspecific intermediate host.
