what is metacercarium
( inf stage of butterflies in sillies flashcards?)
the encysted larval stage of a digenetic trematode (fluke), and it is typically the infective stage for the definitive host.

the germ in the tapeworm egg is called:
a. miracidium
b. oncosphere
c. hexacant stage
oncosphere
what is a cysticercoid
A cysticercoid is a larval stage of certain tapeworms (cestodes), especially those in the family Hymenolepididae and Anoplocephalidae.
Key features of a cysticercoid:
It is a solid-bodied larva (unlike the fluid-filled cysticercus).
Contains a fully developed scolex (tapeworm head) inside.
It is encysted (surrounded by a cyst).
Found in the intermediate host (usually an arthropod, like fleas, beetles, or mites).
the larvacean cysticercus pisiforms develop in
rabbit
name the stages in the development of Pseudophyllidae
unembryonated ovum,
coracidium,
procercoid,
plerocercoid,
adult
IH of Tania saginata is
cattle
characterize and give an example of echinococcus granulosis
Characterization:
Type: Cestode (tapeworm)
Size: Very small adult (3–7 mm), but larval stage causes massive cysts
Definitive host: Dogs and other canids
Intermediate host: Sheep, goats, pigs, cattle, humans (accidental)
Infective stage: Eggs (contain oncosphere)
Larval stage: Hydatid cyst (in liver, lungs, etc.)
what are ovovivipara
female lays embryonated eggs (larva inside egg)
coprological examination of the ruminants revealed the following eggs
