This page provides all possible meanings and translations of the word echinococcus granulosus
Echinococcus granulosus, also called the Hydatid worm or Hyper Tape-worm or Dog Tapeworm, is a cyclophyllid cestode that parasitizes the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease. The adult tapeworm ranges in length from 2 mm to 7 mm and has three proglottids when intact — an immature proglottid, mature proglottid and a gravid proglottid. Like all cyclophyllideans, E. granulosus has four suckers on its scolex, and E. granulosus also has a rostellum with hooks. In canids, E. granulosus causes a typical tapeworm infection, and produces eggs that are passed with the dog's feces. Intermediate hosts include herbivores such as sheep, deer, moose, kangaroos, and wallabies, and any other organism that ingests dog feces. In the intermediate host, eggs hatch into oncosphere larvae that travel through the blood and form hydatid cysts in the host's tissues. These cysts can grow to be the size of a softball or basketball, and may contain several smaller "balloons" inside the main cyst. In the related worm Echinococcus multilocularis, the outer cyst is not present. If the outer cyst ruptures, new cysts can form at a different location in the body. Each smaller section contains several juvenile worms, and dogs may eat millions of them, resulting in very heavy infections. Hydatid cysts occur in organs like the liver, brain and lungs, not in subcutaneous tissue. It has been assumed that infected animals make easier prey for canids. In fact, it has been shown that infected moose are more susceptible to predation by wolves.
U.S. National Library of Medicine
A species of hydatid tapeworm (class CESTODA) in the family Taeniidae, whose adult form infects the DIGESTIVE TRACT of DOGS, other canines, and CATS. The larval form infects SHEEP; PIGS; HORSES; and may infect humans, where it migrates to various organs and forms permanent HYDATID CYSTS.
