Unexpected diversity of the cestode Echinococcus multilocularis in wildlife Canada. International Journal for Parasitology: Parasites and Wildlife 3:81-87
Echinococcus multilocularis is a zoonotic cestode with a distribution encompassing the northern hemisphere that causes alveolar hydatid disease in people and other aberrant hosts. E. multilocularis is not genetically uniform across its distribution, which may have implications for zoonotic transmiss...
