Hepatitis in dogs what is?

  • As the disease spread very quickly due to virus Canine Adenovirus-1 ( CAV-1 ). The species of wild dog, and the dog has not been vaccinated CVA-1 can all get sick, especially with dogs under one year of age. Hepatitis in dogs do not infect humans.
  • Diseases infectious hepatitis in dogs caused by canine adenovirus (CAV-1). Have serum homogeneous on the whole world, similar immunity to adenovirus on people. CAV-1 has antigenic differences compared with CAV-2 (type is produced vaccines for respiratory diseases on dogs). Antigens of CAV-2 was isolated from the intestine puppies hemorrhagic diarrhea. From the dog is kennel cough dogs with signs of diarrhea.
  • Like the adenovirus another, CAV-1 has the ability to resistance in the environment inactivated. High survivability with the type of disinfectant and some types of chemicals. Stable when exposed to a certain frequency of ultraviolet radiation

The method of spread of hepatitis in dogs

  • After exposure, mouth-nose virus positioning in lymph nodes and tonsils. Then it spread to the lymph nodes and the lymphatic system before entering the bloodstream through the thoracic duct. Sepsis lasts 4-8 days after infection. Then the virus infection quickly into the tissues and are present in secretions of the body.
  • Cells in the parenchyma of the liver, endothelial cells of blood vessels of various tissues including the nervous system central is the position in virus geolocation and cause infections and diseases work on these bodies.
  • Complications are often related to the pathogenesis of ICH. Dogs debilitating easily lead to inflammation of the renal pelvis due to virus attack. Internal bleeding tissue (Disseminated intravascular coagulation – DIC) is a frequent complication of ICH and may cause the damage on endothelial cells. Leads to activation of the clotting mechanism, or poor liver function leads to decreased synthesis of clotting factors in the liver.

Pathology of hepatitis in dogs

  • Dogs die in the acute stage of the disease: often the carcass were good, edema and hemorrhagic lymph nodes on the surface and the subcutaneous tissue of the neck. Sinus abdomen may contain liquid color change from in to bright red. Haemorrhage and haemorrhagic on all the surface membrane of the translation bar. Liver swelling, discolouration, stains speckled on the surface and can translate. Fibrin is usually present on the liver surface and in the cracks of time lobes. Typical is the gallbladder thickened and edematous and opaque, translucent blue-white. Fibrin can be deposited on the membrane surface translation bar sinus abdomen. Gastrointestinal bleeding , spleen swollen and bulging out on the cut surface.

  • ICH cause disease on other organs such as hemorrhage and stuffed blood on the renal cortex, lymph nodes, bronchial hemorrhage and edema. Hemorrhage scattered on the brain in the midbrain and caudal brain stem. Lesions on the eye is characterized by clouding of the cornea and causes analysis services.

The histological changes

  • Change histopathology in the liver of the dogs died because of acute hepatitis including necrosis spread throughout the lobules of the liver. On the dog liver necrosis mild degree of necrosis of the liver tissue was determined in the lobules of the liver.
  • Histological changes on the wide-area occur in other organs as the result of injury to the endothelium caused by the virus. Inclusions originally found in the kidney glomeruli, but then is found in vascular endothelium-shaped tubes of the kidneys. The concentration of neutrophils and mononuclear cells in the cortex and medulla of kidney. The slight change often progresses to fibrosis interstitial tissue. Agency, lymphocytes including the lymph nodes, tonsils and spleen congested with the infiltration of neutrophils and cells of the mononuclear. The lymphoid follicles scattered around the area of necrosis. inclusions in the nucleus can be found in the endothelial cells of blood vessels and the tissue cells, the septum alveoli and around the bronchi of the lungs thicken with the accumulation of lymphocytes, alveolar filled with secretions, including erythrocytes, fibrin and liquids.
  • Change on the eye is characterized by inflammation of the iris and the eyelids are u nuts with disruption of endothelial cornea, corneal edema. Iris and eyelids congested with inflammatory cells.
  • Inclusions are seen in ICH was classified as Cowdry type A and both tissues, the epidermis and mômesodermal (we have many in the liver). This makes them become model reasonable for viewing glasses. They are obtained by biopsy or necropsy. Initial hypertrophy of the cells followed by the system chromatin deposited the edge (form center). Nuclear rest is surrounded by a halo of chromosomes. The inclusions original is preferred acid but become preferred alkali such as cling the edge of the chromosome. Attention should be paid inclusions in the liver cells due to ICH and due to the viral disease to another
