33
What disease is commonly called "green slime disease," and why?
Epizootic catarrhal enteritis. One of the clinical signs is a green, mucoid diarrhea.

True or false: Ferrets are highly susceptible to influenza.
True.
37
What is the major distinction between distemper and influenza in ferrets?
Influenza is self-limiting, while distemper is fatal.
38
What characterizes the clinical signs of Aleutian mink disease?
Nonspecific- "nebulopathy" | Usually mild, chronic signs- wasting, anemia, neurological signs in young ferrets
39
How is Aleutian mink disease diagnosed?
Decreased albumin Gamma globulins >20% of total protein Counterimmunoelectrophoresis (CEP)
40
What more common diseases should be considered and ruled out before a diagnosis of Aleutian mink disease is made?
1. GI foreign body 2. Gastroenteritis 3. Lymphosarcoma 4. Insulinoma 5. Lead toxicity 6. Multiple myeloma
41
What are the two different forms of lymphosarcoma in ferrets?
Lymphoblastic or "juvenile" (<1 year old) Lymphocytic or "adult" (>2 years old)
42
True or false: A lymphocyte count of >3,500/uL on CBC is considered diagnostic for lymphosarcoma.
False. It raises suspicion for the disease, but diagnosis should be made by ultrasound, biopsy, etc.
43
How is lymphosarcoma treated in ferrets?
Vincristine, cyclophosphamide, and prednisone
44
Are mast cell tumors in ferrets generally benign or malignant in their biological behavior?
Benign
