Canine Distemper Flashcards
What is the major mode of CDV transmission?
Aerosolization of respiratory exudate
The incubation period of CDV:
1 week to 1 month
Canine distemper is highly contagious, and viral shedding may follow infection for how many days:
60-90 days
How many hours can CDV stay at 25ºc?
48 hours
How many days can CDV stay at 5ºc?
14 days
How long does it take for (CDV) to replicate after an animal is infected?
2-4 days
How long does it typically take for dogs with a good immune response (both humoral and cellular) to clear canine distemper virus (CDV) from their system, even if they initially show symptoms?
3 weeks
Dogs with adequate humoral and cellular immunity might show clinical signs but will clear the CDV from most tissues within 3 weeks.
Identify the tissues
with possible exceptions where CDV can be shed for several months:
CNS, lungs, skin
If a dog’s immune system doesn’t respond effectively to canine distemper virus (CDV), 1. how quickly will severe illness develop, and 2. what is the typical timeframe for death?
- 2-3 weeks
- 3-4 weeks
Dogs with inadequate immune response but survive CDV can shed the virus for:
2-3 months
What are the major organ systems affected by CDV?
Respiratory
Gastrointestinal
Integumentary
CNS
What symptoms are commonly observed during the viremic stage of canine distemper virus infection?
Diphasic fever and general malaise
How long after apparent recovery from the initial, widespread canine distemper infection can neurological signs develop?
1-3 weeks
the involuntary twitching of muscles in a forceful simultaneous contraction highly suggestive of CD
Myoclonus
Increased anti-CDV antibody in the CSF is definitive evidence of:
Neurologic CDV infection
In uncomplicated CDV infection, what is the only consistent pathologic finding:
Thymic atrophy
