Reoviruses are found in many animal species. Feline reoviruses are generally found in the cat's intestinal walls, an infection limits the absorption of nutrients into the intestinal wall and results in diarrhea and dehydration. Reoviruses have been isolated from the faeces and oropharyngeal secretions of cats without any clinical symptoms (clinically healthy), and from cats showing various clinical signs.
The virus is transmitted through contact with infected feces, or by inhalation of airborne virus particles.
Symptoms and diagnosis:
These viruses can be divided into three serotypes regardless of species of origin. They suppress the immune system, and the affected animals may develop various infections. A cat with a reovirus infection will have mild symptoms, diarrhea and gingivitis. In some cases it may lead to more serious complications, like respiratory illnesses (cat flu), conjunctivitis, muscle tremors and ataxia, and some other disorders.
To diagnose roevirus induced diseases full physical examination and complete blood profile is needed. Diagnostic procedures are aimed to differentiate reoviral infection from other infectious agents causing upper respiratory infections for cats.
