Aleutian disease is a parvovirus that ferrets contract from other ferrets and mink. As the virus spreads through a ferret’s body, the ferret’s antibodies -- the protective immune system -- attack the virus, forming complexes which collect in the kidneys, liver, spleen, and other organs causing them to fail.
The disease is incurable and if you have a multi-ferret household, you should consider testing your other ferrets for Aleutian disease and having them euthanized should they be positive.
Ferrets which contract this disease may appear healthy and act as carriers (persistent nonprogressive form), lose weight over time (progressive form) or become very ill and die (another progressive form).
It is also possible for a ferret to have caught the disease and to have fully recovered, not being a carrier (nonprogressive form). However, the vast majority of infected ferrets will become very ill and die (progressive form). Fortunately, this disease is not terribly common.
As stated earlier, Aleutian disease is contracted from other other ferrets or mink, specifically from the animal's bodily fluids (i.e., urine, blood, etc.). The virus was first recognized in mink and was later spread to the ferret species.
Your veterinarian will perform a complete physical exam on the ferret. He/she will take a thorough history from the owner and order a blood chemical profile, a complete blood count, an electrolyte panel, and a urinalysis.
Your veterinarian will also want to do more specific tests, such as a counter electrophoresis to check for high antibody levels. If the ferret is not showing signs of illness because it has a persistent nonprogressive form or a nonprogressive form, it can be tested with immunofluorescent antibody testing to see if it is a source of the parvovirus. Laboratory testing of samples using polymerase chain reaction can also identify the virus.
An in-depth examination of the properties of urine; used to determine the presence or absence of illness
a condition in which an animal must be controlled in some manner in order to prevent a disease from spreading
A protein in the body that is designed to fight disease; antibodies are brought on by the presence of certain antigens in the system.
