CHRONIC NASAL IN CATS: DIAGNOSIS TREATMENT

摘要

Chronic rhinosinusitis is an extremely significant disease, representing one of the two most common causes of sneezin nasal discharge in cats. Chronic rhinosinusitis may follow severe acute upper respiratory tract infection, particularly in kittens oradults cats exposed to an infected cat. Acute upper respiratory tract disease is presumed to be caused by infection with feline herpesvirus type 1, feline calicivirus, Chlamydia felis, or some combination of these agents. Although viral (especially feline herpesvirus type 1) or Chlamydia infection is often implicated as the initiating cause of acute rhinitis, the pathogenesis of idiopathi chronic rhinitis is unknown and it is uncertain whether acute rhinitis is related to the chronic syndrome. Even though cats with idiopathic chronic rhinosinusitis have similar clinical signs, the disease syndrome appears heterogenous among the population perhaps due to individual susceptibility to microbial pathogens, genetic characteristics of the inflammatory response, and environmental factors (e.g., stress) having a role in the development of clinical signs. The complex interrelationship of viral or bacterial organism-involved in the acute disease process combined with individual uniqueness of the inherent inflammatory response may be important factors in genesis of the chronic rhinitis. A thorough understanding of these characteristics would likely facilitate treatment recommendations for patients so affected.
