Canine Herpesvirus Infection Flashcards
Is due to an enveloped DNA canine herpesvirus(CHV) that is relatively unstable outside the host, so close contact is required for transmission.
Infectious canine herpesvirus
Is best known as a severe viral infection of puppies.
Canine herpesvirus infection
It persists in the ganglionic and lymphoid tissues of the oronasal and genital mucosae.
Infectious canine herpesvirus
Canine herpesvirus infection transmission occurs through?
Direct contact with mucosal secretions from the respiratory or genital tracts of infected animals
CHV has an incubation period of
3 to 7 days
Canine Herpesvirus infection replicate in older dogs is restricted to the
Nasopharynx
Genital tracts
Tonsils
Retropharyngeal lymph nodes
Bronchial lymph nodes
Conjunctival tissues
Occasionally lungs
CHV can be harbored in the lymphoid tissues such as:
Tonsils
Parotid salivary gland
Sensory ganglia
Most pups develop systemic herpesvirus infection within
9 days of birth
After oronasal exposure, CHV is first detected in the
Nasal epithelium
Pharyngeal tonsils
Intracellular viremia results in viral spread throughout the body within
3 to 4 days after inoculation
CHV transplacental infections may occur at mid to late gestation and can result in
Abortion of mummified or dead fetuses
Premature or stillborn pups
Weak or runt newborn puppies
CHV infection in postnatally infected puppies is associated with an acute and fatal illness, primarily occurring between
1 to 3 weeks of age
CHV Infected puppies appear:
Dull and depressed
Lose interest in nursing
Lose body weight and pass soft
Yellow-green feces
Frequently manifest by serous to mucopurulent or rare hemorrhagic nasal discharges
Rhinitis
