Oral Route
Habitat
Small Intestine
Spoon-like (Almond) part of the cestode body; Anterior Attachment Organ
Scolex
Protrusible structure, either armed (with hooks) or Unarmed (withoud hooks)
Rostellum
Majority. with 4 Cuplike sucker; Diphyllobothrium latum with 2 Slidike Suckers
Suckers “Grooves” “Acetabula”
Region of growth; Point of proliferation for the next set of segments
Neck
Chain of Segments/Strobila; Stained with India Ink
Proglottids
Proglottids found nearest to the neck
Immature
Proglottids filled with eggs, presence of egg in the uterus, farthest from the head; can be detached (apolysis)
Ripe/Gravid
Part of cestode body that is found at the Medial Surface and in Diphyllobothrium lafum. Where the Egg Exits
Uterine Pore
Site at where Male and Female Organs Meet
Genital Pore
Eggs: All eggs are unoperculated and mature (embryonated) except for …
Diphyllobothrium latum
Protects the Embryo, contains 6 hooklets
Oncosphere
WELL-developed Reproductive organs of cestodes:
Testes, Ovary, Uterus
TRUE OR FALSE: Nonrecovery of scolex would mean successful treatment
FALSE. *UNSUCCESSFUL treatment
Imitates the tapeworm, Proglottid Activates and
become Infectious
Alcohol Ingestion
known as False Tapeworm
Pseudophilidian
known as True Tapeworm
Cyclophilidian eg. T.solium and saginata
Species which require vertebrate intermediate host:
D. caninum
Species which require invertebrate intermediate hosts:
H. nana
Has a life span of 25 years
D. latum, T. saginata, and T. solium
Usually has a life span of <1year
D. caninum and H. diminuta
Perhaps has a lifespan of many years as a result of autoinfection:
H. nana
