Infectious canine hepatitis is an Acute liver infection in dogs caused by canine Adenovirus type-1 (CAV-1). The Virus is spread in the feces, urine, blood, saliva, and nasal discharge of infected dogs. It is contracted through the mouth or nose, where it replicates in the Tonsil s. The virus then infects the Liver and Kidney s. The Incubation Period is 4 to 7 days. Symptoms include Fever , depression, loss of appetite, coughing, and a tender abdomen. Cornea l Edema and signs of liver disease, such as Jaundice , vomiting, and Hepatic Encephalopathy , may also occur. Severe cases will develop Bleeding disorders. Death can occur secondary to this or the liver disease. However, most dogs recover after a brief illness. Diagnosis is made by recognizing the combination of symptoms and abnormal blood tests that occur in infectious canine hepatitis. A rising Antibody Titer to CAV-1 is also seen. The disease can be confused with Canine Parvovirus because both will cause a low White Blood Cell count and bloody diarrhea in young, unvaccinated dogs. Treatment is for the symptoms. Most dogs recover spontaneously without treatment. Prevention is through Vaccination . Most combination Vaccine s for dogs contain a modified canine adenovirus type-2. CAV-2 is one of the causes of respiratory infections in dogs, but it is similar enough to CAV-1 that vaccine for one creates Immunity for both. CAV-2 vaccine is much less likely to cause side effects than CAV-1 vaccine. CAV-1 is destroyed in the environment by steam cleaning and Quaternary Ammonium Compound s. Otherwise, the virus can survive in the environment for months in the right conditions. It can also be released in the urine of a recovered dog for up to a year. REFERENCE |
