*Infects and replicates in the oropharynx
 
*Viremia as the virus reaches endothelial cells
 
*Attacks the endothelial lining of '''gall bladder''', '''liver sinusoids''', and '''Kuppfer cells'''
 
*Resulting '''heptatitis''' is followed by severe abdominal pain and often death
 
*Post Mortem: swollen, hemorrhagic liver, ascites, and oedema of the gall bladder
 
*In older dogs, may present more mildly with lymph node enlargement and chronic interstitial nephritis
 
*In foxes: virus replicates in the endothelia of the brain resulting in neuronal damage, fits, and paralysis

====Diagnosis====
 
*Intranuclear inclusion bodies in hepatocytes can be seen under H&E staining
 
*Vascular endothelium can be stained for viral '''antigen''' by '''immunofluorescence'''
 
 
====Control====
 
In an outbreak
 
*Isolate infected dogs
 
*Disinfect premises
 
To prevent
 
*'''Vaccination''': tissue culture adaptation that may be live or inactivated
 
*Cross protection with CAV2
 
*Live vaccines are known to cause keratitis in Afghans, Red Setters and Saluki

Causes Infectious Canine Hepatitis

Hosts

  • Dogs
  • Foxes are very susceptible (Fox Encephalitis)

Epidemiology

  • Transfers easily via ingesting infected urine, feces or respiratory secretions
  • Can be transferred by handlers, infected surfaces, etc.
