**6. Parasite classification**

The classification of Echinococcus genus has been controversial for a long time, and 16 species and 13 subspecies of this genus have been described, based on the difference in the structural and phenotypic properties of the parasite and the characteristics of the host and its type, but only 4 of them are taxonomically adopted: *E. granulosus*, *E. multilocularis*, *E. oligarthrus*, and *E. vogeli* [13]. According to [14], the classification system of granulocytic parasitic parasite is as follows:

Kingdom: Animalia Phylum: Platyhelminthes Superclass: Eucestoda Class: Cestoda Subclass: Cestoda Order: Cyclophyllidea (Ben; Braun, 1900) Family: Taeniidae (Ludwig, 1886)

Genus: Echinococcus (Rud, 1801) Species: granulosus (Batsch, 1786)
