![]() ![]() If you have an invasive infection and the tapeworm forms a cyst or a lump, your doctor may prescribe an anthelmintic drug to shrink the mass. Antiparasitic drugs used to treat intestinal infections may include:Īfter completing treatment, you’ll have a follow-up stool sample to ensure the infection has cleared. If a tapeworm doesn’t leave your body, your doctor will recommend a treatment based on the type of infection.įor an intestinal infection, you’ll need to take an oral medication to get rid of the tapeworm. This is why some people never have symptoms or only have mild symptoms. Sometimes, the tapeworm leaves the body on its own. Useful websites for further information about Echinococcus Tapeworm.It’s important to note that some tapeworm infections don’t require treatment. The presence of hydatid cysts in livestock at slaughter is generally not of concern, and if present, is trimmed from the edible product. In ungulates, the presence of large numbers of hydatid cysts can lead to difficulty breathing. Normally, Echinococcus granulosus is not harmful to canids but heavy infections may be associated with diarrhea or poor body condition. What is the significance of Echinococcus granulosus to wildlife and livestock? Were wolves examined and treated for Echinococcus granulosus before they were released in Wyoming?Īll wolves captured in Canada for relocation to Yellowstone National Park and central Idaho were treated for lice, roundworms and tapeworms before being released. If your dog has had access to ungulate carcasses, consult your veterinarian for proper deworming protocols. Do not feed uncooked meat or organs of deer, elk, moose or sheep to dogs. When outdoors, avoid touching or disturbing scat. Always wash your hands after handling a dog that has access to ungulate carcasses. Regular deworming of domestic dogs and good hygienic practices by humans are the best methods to prevent infection in humans. Those hunting or trapping canids in Wyoming are encouraged to wear latex or rubber gloves when field dressing and skinning their animals and wash their hands thoroughly afterwards. How do I prevent getting infected with this parasite? Throughout the world, most human cases occur in indigenous people with close contact with infected dogs. Treatment may involve administration of drugs and/or surgery to remove the cysts. Cysts can develop over long periods of time before any symptoms are evident. In humans, larval tapeworms usually develop into cysts in the liver or lungs. Where the parasite is found in wild canids and wild ungulates, most public health agencies consider the public health risk to be very low. Humans cannot be infected by ingesting larval tapeworms from ungulates. These can be ingested after handling contaminated soil or contaminated canid scat or fur and then touching the face or eating before washing hands. Yes, humans are not a natural host for the parasite but can be infected by ingesting eggs which are passed with the feces from an infected canine. Only a few cases have been documented in Wyoming elk,moose and one mule deer, but the definitive host origin is unknown.Ĭan humans get infected with Echinococcus granulosus? In the United States, the northern biotype of Echinococcus granulosus has been found in several states including Wyoming. It is endemic in most sheep raising areas of the world. The southern or domestic biotype circulates between dogs and domestic ungulates, especially sheep. This is thought to be the biotype seen in Wyoming wildlife and does not typically infect domestic livestock. The northern biotype above 45˚ latitude circulates between canids (wolf, coyote, dog) and cervids (moose, elk, deer, caribou, reindeer). Where is Echinococcus granulosus found? Is it found in Wyoming?Įchinococcus granulosus has a worldwide distribution with two recognized biotypes. Intermediate hosts ingest the eggs while grazing, where the eggs hatch and develop into larvae. Adult tapeworms, 3-5 mm long, produce eggs which canids pass in their feces. Definitive hosts are exposed to larval tapeworms when ingesting infected ungulates. Canids (dogs, wolves, coyotes, foxes) are definitive hosts where larval tapeworms mature and live in the small intestine. Ungulates (deer, elk, moose, domestic sheep, and domestic cattle) are intermediate hosts for larval tapeworms.
