||Canine distemper virus
Canine distemper is a
affecting animals in the families
possibly Felidae (though
not domestic cats;
panleukopenia is a similar, but different, virus exclusive to cats).
Dogs from four months to four
years old are particularly susceptible. It prevails most in
and autumn. Canine
distemper virus (CDV) spreads
through the air and through contact with infected bodily fluids. The time
between infection and disease is 14 to 18 days.
Canine distemper virus has a tropism for lymphoid, epithelial, and nervous
tissues. Therefore, the typical pathologic features of canine distemper include
lymphoid depletion (causing
immunosuppression and leading to secondary infections), interstitial
of foot pads . Histologic
examination reveals intranuclear and intracytoplasmic
bodies in numerous tissues.
- Dullness and redness of the
- Discharge from nose
- Vomiting and
- Loss of appetite
- Weight loss
- Thickened footpads
The above symptoms, especially fever, respiratory signs, neurological signs,
and thickened footpads found in unvaccinated dogs strongly indicate canine
distemper. Finding the virus by various methods in the dog's
cells gives a definitive diagnosis.
Treatment and prevention
There is no specific treatment for canine distemper. The dog should be
treated by a
veterinarian, usually with
secondary bacterial infections,
intravenous fluids, and nutritional supplements. The prognosis is poor.
There exist a number of
vaccines against canine distemper for
domestic ferrets, which in
many jurisdictions are mandatory for pets. The type of vaccine should be
approved for the type of animal being inoculated, or else the animal could
actually contract the disease from the vaccine. Animals should be
infected. The virus is
destroyed in the environment by routine cleaning with disinfectants.
