Rabies Flashcards
How long can domestic dogs, cats, and ferrets shed rabies virus before showing clinical signs?
Up to 10 days
How does rabies virus travel from the inoculation site to the brain?
Peripheral nerves
What is the typical range for the incubation period of rabies in dogs after exposure?
21-80 days
Which form of rabies is characterized by pronounced aggression and irritability?
Furious form
What is a common clinical sign in the paralytic form of rabies in dogs?
Dropping of the lower jaw
Which diagnostic test is the current test of choice for rabies diagnosis?
Immunofluorescence microscopy on fresh brain tissue
Which brain regions are essential for rabies diagnosis using immunofluorescence microscopy?
Medulla oblongata and cerebellum
According to the NASPHV, what is the recommended action for an unvaccinated dog exposed to rabies?
Immediate euthanasia
What is the recommended quarantine period for an unvaccinated dog, cat, or ferret exposed to rabies if the owner refuses euthanasia?
4-6 months
What is the recommended action for a currently vaccinated domestic animal exposed to rabies?
Revaccination and observation for 45 days
What is the recommended course of action for a healthy domestic dog, cat, or ferret that bites a person?
Confinement for 10 days
Which of the following is NOT a reliable clinical sign of rabies in animals?
a) Acute behavioral changes
b) Progressive paralysis
c) Sudden anorexia
d) Chronic dermatitis
Chronic dermatitis
What is the prodromal period in rabies characterized by?
Vague nonspecific signs
Why is clinical diagnosis of rabies unreliable for public health decisions?
Clinical signs are highly variable and nonspecific.
What is the role of oral vaccination in rabies control?
To reduce rabies in wildlife reservoir populations.
What is the significance of the term “canine rabies” from an epidemiologic perspective?
It specifies rabies maintained by dog-to-dog transmission.
Why are cats considered effective rabies vectors but not reservoirs?
There is no documented cat-to-cat transmission perpetuating rabies.
What is the significance of priapism in rabid animals?
It is a neurological sign of hyperexcitability.
What is the primary mode of rabies transmission?
Introduction of virus-laden saliva into tissues
Aerosol transmission of rabies virus occurs in a very specialized conditions, and it may occur via direct attachment of the virus to which nerve endings?
Olfactory nerve endings
What are the most reliable signs, regardless of species, of rabies infection?
Acute behavioral changes
Progressive paralysis
What are the three general phases of rabies?
Prodromal
Acute excitative
Paralytic/Endstage
How long does the prodromal period typically last in rabies-infected animals?
1-3 days
What type of clinical signs are observed during the prodromal period of rabies?
Vague nonspecific signs
