Section I

tapeworms
The tapeworms Echinococcus granulosus and Echinococcus multilocularis,
which are sometimes carried by dogs and cats, can cause a rare, but potentially fatal, disease, alveolar hydatid disease (AHD). The tapeworm species
E. multilocularis was originally confined to the Alaska coast, the cold tundras
of Canada, and the Eastern Hemisphere; however, it has now been identified
in the Dakotas, the Central Plains, and as far south as the Carolinas. Possible
illegal shipments of animals have been linked to the spread of the disease.
Fox, coyotes, and mice are the normal intermediate hosts (a host that the
parasitic organism lives on or in during an immature stage) for this species
of tapeworm, but the parasite is now appearing in domestic dogs and cats.
The tapeworm species E. granuosus is found in California, Utah, Arizona,
and New Mexico, where it normally uses sheep as the intermediate host.
Infective E. multilocularis and E. granuosus eggs, accidentally ingested by
humans, hatch in the small intestine, penetrate the intestinal wall, and migrate
to the liver, where they produce parasitic tumors or cysts. See Figures 2-21 and
2-22. Clinical signs may not appear until the growth of the cyst has progressed
for several years. Surgical removal of the cyst is the preferred treatment,
although in many cases the cyst has affected other organs and may not be
removable. AHD has a fatality rate of 50 to 75 percent, with or without surgery.
