A cat is infested with mites that you identify as Dermanyssus species. You ask
the client:
A) Whether or not the cat has access to birds
B) Whether or not the cat is a mouse hunter
C) Whether or not the cat spends a lot of time near rabbit dens
D) Whether or not the family dog has been pruritic
Whether or not the cat has access to birds
The term "measly beef" refers to the presence of:
A) Eggs of Taenia saginata in muscle tissue
B) Cysticerci of Taenia saginata in musle tissue
C) Sarcocysts (tissue cysts) of Sarcocystis in muscle tissue
D) Tissue cysts of Toxoplasma gondii in muscle tissue
E) Tissue cysts of Neospora caninum in muscle tissue
Cysticerci of Taenia saginata in musle tissue
Neospora caninum infection in cattle causes:
A) Weight loss
B) Bloat
C) Sterility in bulls
D) Abortion
E) Chorioretinitis in aged (>10 years) animals
Abortion
Infection with which of the following parasites has been associated with head

D) Passalurus ambiguous

A 2-year-old indoor/outdoor neutered male cat presents with lethargy,
depression, and anorexia of two days duration. Physical examination reveals a
profoundly icteric, moribund cat with pale mucous membranes and severe
dehydration. These organisms were found on blood smear. As you explain
your treatment plan and prognosis to the client, she asks if there is anything
she can do to protect her four other cats at home from becoming infected.
What do you recommend?
Prevent ingestion of rodents and rabbits
Flea control, including keeping cats indoors and on highly effective flea
control products
Tick control, including keeping cats indoors and on highly effective tick
control products
Prevent ingestion of birds
Administer a monthly heartworm preventative with intestinal parasite control
Tick control, including keeping cats indoors and on highly effective tick control
products
Anaplasma marginale
A five-year-old horse presents with tail rubbing and anal pruritus. You suspect
infection with the equine pinworm, Oxyuris equi. What diagnostic test is
preferred to recover the eggs of this parasite?
A) Direct smear
B) Passive fecal flotation with sodium nitrate
C) Centrifugal fecal flotation with sugar solution
D) Fecal sedimentation
E) Scotch tape test
Scotch tape test
Treatment of dogs with severe, generalized demodectic mange should always
include:
A) Antibiotics
, Page 4 of 78
B) Anti-mite agents
C) Anti-fungal agents
D) Antibiotics and anti-mite agents
E) Anti-fungal agents and anti-mite agents
Antibiotics and anti-mite agents
A litter of 2-week-old puppies presents with acute lethargy. On physical
examination the puppies are moribund, cold, and have markedly pale mucous
membranes. You suspect acute anemia due to hookworm infection. The next
step in managing these puppies is:
Prophylactically deworm with pyrantel pamoate
Perform a fecal flotation and only deworm if eggs are detected
Perform CBC, serum chemsitry, U/A, and abdominal radiographs on each pup
Hold for quiet observation for 48 hours to monitor progression of disease
Bathe each puppy to insure ectoparasites are eliminated
Prophylactically deworm with pyrantel pamoate
These eggs were found on fecal flotation from a 10-year-old spayed female
indoor/outdoor cat. Is this an unusual diagnosis?
No, this parasite is commonly seen in both kittens and adult cats
Yes, this parasite is extremely rare in cats in the United States
Yes, this cat is likely immunocompromised and thus the immunity that would
prevent the infection has lapsed
Yes, this parasite is generally only found in kittens
No, this parasite is commonly seen in the feces of coprophagic cats that
ingest the eggs in the feces of another animal
No, this parasite is commonly seen in both kittens and adult cats
What aspect of the life cycle of Habronema and Draschia spp. accounts for the
seasonal pattern seen in cutaneous habronemiasis, or summer sores, in
affected horses?
The bacterial organisms which cause the secondary infections responsible for
the lesions only flourish in the humid summer months
