Echinococcus

 [e-ki″no-kok´us]
a genus of small tapeworms.
Echinococcus granulo´sus a species parasitic in dogs and wolves and occasionally in cats; its larvae may develop in nearly all mammals, forming hydatid cysts in the liver, lungs, kidneys, and other organs. It reverses the usual process of development in human and animal hosts: the adult is found in the intestine of dogs, whereas the larva develops in the human intestine, penetrates the intestinal wall, and settles in various organs, most often the liver, where it forms a cyst (hydatid cyst) that grows slowly. Treatment is by surgical removal of the cyst. This type of worm infection is fortunately not common in the United States.
Echinococcus multilocula´ris a species whose adult forms usually parasitize the fox and wild rodents, although humans are sporadically infected. It resembles E. granulosus, but the larvae form alveolar or multilocular rather than unilocular cysts.

Echinococcus

(e-kī'nō-kok'ŭs),
A genus of small taeniid tapeworms, two to five segments in adult worms; adults are found in various carnivores but not in humans; larvae, in the form of hydatid cysts, are found in the liver and other organs of ruminants, pigs, horses, rodents, and humans (for example, sheep herders living closely with their infected dogs, contact with infected feces).

Echinococcus

/Echi·no·coc·cus/ (e-ki″no-kok´us) a genus of small tapeworms, including E. granulo´sus, usually parasitic in dogs and wolves, whose larvae (hydatids) may develop in mammals, forming hydatid tumors or cysts chiefly in the liver; and E. multilocula´ris, whose larvae form alveolar or multilocular cysts and whose adult forms usually parasitize the fox and wild rodents, although humans are sporadically infected.

echinococcus

/echi·no·coc·cus/ pl. echinococ´ci   an individual organism of the genus Echinococcus.

echinococcus

(ĭ-kī′nə-kŏk′əs)
n. pl. echino·cocci (-kŏk′sī′, -kŏk′ī′)
Any of several parasitic tapeworms of the genus Echinococcus, the larvae of which infect mammals and form large, spherical cysts in the liver or lungs, causing serious or fatal disease.

Echinococcus

[ekī′nōkok′əs]
Etymology: Gk, echinos, prickly husk, kokkos, berry
a genus of small tapeworms that primarily infect canines. See also echinococcosis.

E·chi·no·coc·cus

(ĕ-kī'nō-kok'ŭs)
A genus of very small tapeworms; adults are found in various carnivores but not in humans; larvae, in the form of hydatid cysts, are found in the liver and other organs of ruminants, pigs, horses, rodents, and, under specific epidemiologic circumstances, humans (in whom disease is called hydatid disease). Worm has been studied in offensive biowarfare programs.

(e-ki?no-kok'us) [L. echinus, fr Gr echinos, hedgehog, sea urchin + coccus]
A genus of very short tapeworms.

ECHINOCOCCUS GRANULOSUS CYSTS

Echinococcus granulosus

A species that infests dogs and other carnivores. Its hydatid (larva) develops in other mammals, including humans, and causes the formation of hydatid cysts in the liver or lungs. Synonym: dog tapeworm
See: illustration; hydatid

Echinococcus hydatidosus

A species characterized by development of daughter cysts from the mother cyst.
See: hydatid

Echinococcus multilocularis

A species that primarily infests foxes and moles. It is the cause of alveolar hydatid disease in humans, one of the deadliest helminthic infections.

Echinococcus oligarthrus

A species found primarily in the tropics, where it colonizes wild cats. It may cause echinococcal cysts in humans.

Echinococcus vogeli

A species that causes polycystic hydatid disease (a neotropical parasitic infection).

echinococcus

(ĕ-kī″nŏ-kok′ŭs) (ĕ-kī″nŏ-kok′sī″) plural.echinococci
A tapeworm of the genus Echinococcus.

echinococcus

One of several tapeworms of the genus Echinococcus , the larvae of which form large, spherical cysts in the tissues, including the brain, causing serious or fatal disease.

echinococcus

a larval tapeworm (metacestode) which develops several daughter cysts each of which has several scoleces (pl. of SCOLEX).

Echinococcus

a genus of small tapeworms of the family Taeniidae.

Echinococcus granulosus
a species parasitic in dogs and wolves and occasionally in cats; its larvae may develop in ungulates and macropods, forming hydatid cysts in the liver, lungs, kidneys and/or other organs.
Echinococcus multilocularis
a species whose adult stage usually parasitizes the fox, dog and cat. It resembles E. granulosus, but the larvae form alveolar or multilocular rather than unilocular cysts and occur principally in rodents but can infect humans.
Echinococcus oligarthus
occurs in wild cats with larval stages in rodents.
Echinococcus vogeli
occurs in domestic and wild dogs with intermediate stages in rodents and humans.
