The terminal segment is the longest and broadest.Eggs are spherical in shape and resemble the egg of Taenia solium and Teania saginata. Echinococcus granulosus; Morphology, Life Cycle and Pathogenesis.

An itermidiate host such as Sheep, cattle, pig, etc swallow the eggs while grazing in the  field and human particularly children swallow the eggs due to intimate handling of infected dogs or other definitive hosts.In the duodenum, hexacanth embryos are hatched out.

In many cases, it requires extensive surgery and need prolonged drug therapy. E granulosus is discussed separately from the other 3 species, notably Echinococcus multilocularis, which causes alveolar echinococcosis, because of marked differences in epidemiology, clinical features, diagnosis, … It is found all over the world.

Alveolar echinococcus in older indiduals(>50 yrs) Seen in people who are in contact with dogs It is the scolex of the future adult worm.The eggs are discharged with the feces of the definitive hosts such as Dog, wolf, fox and jackel. Echinococcus granulosus (sensu lato) causes cystic echinococcosis and is the form most frequently encountered. Two exclusively New World species, E. vogeli and E. oligarthrus, are associated with “Neotropical echinococcosis”; E. vogeli causes … Cyst contains thousands of individual protoscolices as well as many daughter cysts. Echinococcus granulosus is a parasitic worm which belongs to the family Taeniidae under order Cyclophyllidea of class Cestoda. A definitive host such as dog becomes infected by ingestion of the larva with the infected viscera of an intermediate host such as cattle.

Some embryos may pass the liver, enter the pulmonary circulation and filter out lungs (the second filter). The antigen is used for immunological tests.Clear, colorless with specific gravity of 1005-1010 and pH of 6.7. About eight hours after infestation, the embryo penetrates through the mucous of the intestine and enters the tributaries of portal vein. Another species, E. multilocularis, causes alveolar echinococcosis, and is becoming increasingly more common.

Ultrasonography imaging is the best technique to diagnose of both cystic and alveolar echinococcosis.Different serological tests are also effective to detect specific antibodies.The best available technique is the ELISA which is suitable for the detection of antigens in feces.PCR (polymerase chain reaction) is also employed to detect the parasite from X-rays, CAT scans etc. The egg is infective to human, cattle, sheep and other herbivorous animals.Larval forms are found within the hydatid cyst.
