The genus Echinococcus includes nine types of tapeworms called echinococci . The genetic variation within Echinococcus granulosus is relatively high, which means that new genotypes are often described. The fox tapeworm ( E. multilocularis ) shows only slight genetic variation. They are heteroxic and therefore need two hosts for their development ; a predator host ( dog , cat ) and a prey host ( sheep , camels , mice ). The dog tapeworm ( E. granulosus ) also has a corresponding host change.
Illnesses triggered by this, such as lung infestation, are known as echinococcosis . Four of the previously known species can occur as false intermediate hosts in humans, with great differences in pathogenicity between the species and individual genotypes.
In Germany, the direct or indirect detection of Echinococcus sp. Not notifiable by name according to § 7 paragraph 3 of the Infection Protection Act (IfSG).
