Cestodes Flashcards
- DH canids; IH rabbits
- Metacestode:cysticercus (liver/mesentery)

Taenia pisiformis
- DH canids; IH ruminants, swine
2. Metacestode:cysticercus (peritoneal membranes)
Taenia hydatigena
- DH felids; IH rodents
- Metacestode:strobilocercus (liver/peritoneum)
- Only tape of cats
Taenia taeniaeformis
- DH canids; IH sheep
- Metacestode: coenurus
- Important internationally in sheep production
Taenia multiceps
- DH canids; IH rabbits and cats
- Metacestode: coenurus
- Important in cats: Coenurus in brain
Taenia serialis
- DH human; IH swine
- Humans can become IH; pathology from cysticercus
- Metacestode:cysticercus (muscle)
- Pork tape, “measly pork”
Taenia solium
- DH human; IH cattle
- Metacestode:cysticercus (muscle)
- Beef tape, “measly beef”
Taenia saginata
- DH canids; primarily ungulates
- Metacestode: unilocular hydatid cyst (liver/lung/other)
- Slyvatic cycle in wildlife; Domestic cycle in domestic species
- Zoonotic risk: humans as IH
Echinococcus granulosus
- DH canids; IH rodents
- Metacestode:multilocular hydatid cyst (abdominal cavity)
- Slyvatic cycle in wildlife; Domestic cycle in domestic species
- Zoonotic risk: humans rarely IH
Echinococcus multilocularis
i. DH felids and canids; IH C. felis (flea)
ii. Metacestode:cysticercoid
iii. Double pored (each side)
iv. PPP 2-3 weeks, shorter than usual 1.5-2 months
Dipylidium caninum
i. DH ruminants; IH oribatid mites
ii. Metacestode:cysticercoid
iii. Square egg
Moniesia sp
- DH equids; IH oribatid (free living mites)
- Metacestode:cysticercoid
- Can be found outside SI unlike all other tapes
- Proglottids and eggs sheg; proglottids unable to be seen with eye
- Eggs have “pyriform apparatus”
- Adults small and square shaped
Anoplocephala perfoliata
- Very similar to A. perfoliata; larger and no lappets, relatively harmless
Anoplocephala magna
- Similar to A. perfoliata; smaller and no lappets, relatively harmless
Paranoplocephala mamillana
i. DH small ruminants (rarely cattle/deer); IH booklice/bark lice
ii. Metacestode:cysticercoid
iii. Proglottids shed in feces; egg packets similar to D. caninum
