<FlashCard questions="13">
 
|q1=Fill in the missing words about cestodes:<p>
 
A cestode (tapeworm) is a chain (???) of progressively maturing reproductive units called ??? anchored at one end to the intestinal wall by a hold-fast organ called the ???.

|a1=
 
*strobila
 
*proglottids
 
*scolex
 
|l1=Cyclophyllidea#Introduction
 
|q2=What species of Taenia occur in dogs?
 
|a2=
 
*Taenia ovis
 
*Taenia hydatigena
 
*Taenia pisiformis
 
*Taenia multiceps
 
*Taenia serialis
 
|l2=Taenia#Introduction
 
|q3=Describe the features of a cysticercus
 
|a3=Fluid filled bladder, containing a single invaginated head (protoscolex) - seen as a white blob on the wall of the cyst
 
|l3=Cyclophyllidea#Life-Cycle
 
|q4=In which host(s) would you expect to find the cysticercus of ''T. hydatigena'' and where in the host might it be found?
 
|a4=
 
*Sheep (mostly)'
 
*Cattle
 
*Pigs
 
*Found in the peritoneal cavity
 
|l4=Taenia#Structure and Function
 
|q5=What is the difference between a coenurus and a cysticercus?
 
|a5=
 
*A coenurus is a fluid filled bladder with multiples (dozens) of inverted scolices attached to the wall
 
*Whereas the cysticercus  has only a single inverted scolex.
 
|l5=Cyclophyllidea#Life-Cycle
 
|q6=How does the distribution of hydatid cysts differ in sheep, horses and humans?
 
|a6=
 
*Sheep = most are in the lungs with smaller numbers in the liver
 
*Horses = nearly all are in the liver
 
*Humans = most are in the liver, with some in the lungs and a few elsewhere
 
|l6=Echinococcus#Life-Cycle
 
|q7=What tapeworms occur in the cat?
 
|a7=
 
*Taenia taeniaeformis
 
*Dipylidium
 
|l7=Taenia#Introduction
 
|q8=Why is it so difficult to prevent many cats from becoming re-infected with ''T.  taeniaeformis''?
 
|a8=The intermediate hosts are mice and other small mammals that are hunted
 
|l8=Taenia#Taenia spp of the Cat
 
|q9=Where in the host (horse) would you expect to find ''Anoplocephala''?
 
|a9=Ileo-caecal junction
 
|l9=Anoplocephala#Life-Cycle
 
|q10=Why are ''Anoplocephala'' eggs rarely seen on routine faecal examination?
 
|a10=They are dense structures and do not always float in the flotation media used in routine diagnosis
 
|l10=Anoplocephala#Life-Cycle
 
|q11=Why is it so difficult to prevent grazing horses from becoming re-infected with ''Anoplocephala''?
 
|a11=The intermediate hosts are ubiquitous free-living pasture mites
 
|l11=Anoplocephala#Life-Cycle
 
|q12=Describe the appearance of ''Moniezia
 
|a12=
 
*Long tapeworm (up to 2m)
 
*Segments much wider than they are long
 
|l12=Moniezia#Introduction
 
|q13=Why is ''T. solium'' more dangerous to human health than ''T. saginata''?
 
|a13=If T. solium eggs get into the human small intestine, they will hatch and cysticerci can establish in the musculature and CNS. This does not happen with T. saginata.
 
|l13=Taenia#T. solium, the Pork Tapeworm of Humans
