Echinococcus (the fox tapeworm)

Echinococcus multilocularis is a small tapeworm normally found in the intestinal tract of wild canids (e.g. coyotes, foxes) and sometimes dogs. For these animals, having this worm in the gut doesn’t cause a problem. The main concern is when something (or someone) ingests tapeworm eggs that are passed in feces of these canids.
