Who gets pinworms? Equines and Canines
Explain why most anthelmintics (de-wormers) that can clear up nematode infestations can't get
tapeworms. Because anthelmintics do not respond the same to anthelmintics (de-
wormers). Tapeworms need to be paralyzed with another de-wormer.
Identify problems associated with external parasites. Incessant scratching; scabs and skin
abrasions; abrasions cause skin damage and disease; secondary bacterial infections; blood loss -
-> anemia --> death in young animals; carriers of internal parasites (fleas)
What is flea dirt? What is commonly found? Pepper-like specks on animal = flea feces
composed of blood. Found on skin.
What is pediculosis? Conditions of lice infestation
, What is a nit? Eggs = lice
What is acariasis? Condition of tick infestation
What are the two primary types of lice? What morphological features help to distinguish
between the two types? Biting lice = live on mammals and birds. Chewing/sucking lice =
mammals only. Biting lice have mouth parts designed for chewing not sucking.
More than _________ are called lice. Louse
Which species are most commonly affected by lice? Are they a big problem in dogs/cats?
Livestock. No not a problem in dogs/cats.
Which external parasite can live for long periods of time off the host? Ticks
What is an immature tick called? How do you distinguish between a mature and immature tick
(based on morphology)? Seed tick. Immature ticks have 6 legs while adult ticks have 8.
