  Echinococcus Granulosus, The Dog Tapeworm   (Site not responding. Last check: 2007-11-05)
Echinococcus granulosus is the Human tapeworm that comes from dogs, as well as, other members of the canidae family (foxes, coyotes, wolves, etc.) and cats.
The dog is the definitive host and passes the eggs of the adult Echinococcus granulosus tapeworm through its stool.
Infestation of the Echinococcus granulosus in humans is rare, but the numbers are increasing due to the trapping and transporting of wild coyotes, foxes, and wolves into the United States.

 Reemergence of canine Echinococcus granulosus infection
As a consequence of large-scale outdoor slaughter of sheep during the 2001 foot and mouth disease (FMD) outbreak in the United Kingdom and the possibility of increased risk for transmission of Echinococcus granulosus between sheep and dogs, a large survey of canine echinococcosis was undertaken in mid-Wales in 2002.
An Echinococcus coproantigen-positive rate of 8.1% (94/1,164) was recorded on 22% of farms surveyed, which compares to a rate of 3.4% obtained in the same region in 1993.
Echinococcus granulosus infection in sheep and dogs has been known to be endemic in parts of Wales and the English borders for many decades.

In this study, the prevalence and distribution of Echinococcus granulosus was evaluated in 911 dogs and 1231 sheep within the country of Kazakhstan.
A preliminary evaluation was made for overall prevalence of Echinococcus granulosus, age vs. prevalence relationships, type of distribution, frequency of infection, and overall mean worm burden and variance.
The main objective of this study is to attempt to evaluate the extent of Echinococcus granulosus infection in both the definitive and intermediate hosts in the hope of eventually arriving at a plan which will enable the spread of this dangerous parasite to be kept in check.

Echinococcosis/hydatidosis is a zoonotic parasitic disease caused by the dog tapeworm Echinococcus and its larval stage, the hydatid cyst.
Echinococcus granulosus is primarily maintained through domestic (Figure 6) and sylvatic life cycles.
The adult echinococcus is considered to be rather harmless to the definitive host, except when it occurs in large numbers, which may cause severe enteritis.

Echinococcus granulosus infection in sheep and dogs has been known to be endemic in parts of Wales and the English borders for many decades (1-3).
Ovine hydatidosis rates in the intervention area dropped from 23.5% to 10.5% after that period, and experimental use of sentinel lambs confirmed that transmission of E. granulosus was significantly reduced by this regime (8).
Fecal supernatants were tested for Echinococcus coproantigens by using a standard ELISA that used a capture antibody against E. granulosus adult somatic antigens (12) as had been used in the previous survey of canine echinococcosis in the Powys area (7).

Echinococcus granulosus is a tapeworm parasite that in its larval form can cause hydatid disease, which is characterized by cysts forming within the victim's body.
The adult form of Echinococcus granulosus exists benignly in carnivores, which are primarily infected by eating the raw or undercooked internal organs of other animals that contain hydatid cysts.

The large cystic lesion of the liver is a hydatid cyst of Echinococcus granulosus, a cestode (tapeworm) infection in which man becomes the intermediate host.
The laminated wall of the cyst seen here is lined by a germinal epithelium from which daughter larvae develop by the thousands and float into the clear fluid filling the unilocular cyst of Echinococcus granulosus.
These larvae (several of which are seen here microscopically with characteristic hooklets of the scolex) settle out and form the so-called "hydatid sand".
