Reoviruses are found in a great variety of animal species, including humans and almost every species of mammal. A reovirus infection is caused by a group of viruses with double-stranded RNA. This infection limits the absorption of nutrients into the intestinal wall and causes diarrhea and dehydration.
Animals get infected by a direct contact with the infected feces or airborne virus particles. Reovirus infection is common, but it does not cause specific disease, the virus has immunosuppressive value, which can promote other viral and bacterial infections.
Symptoms and diagnosis:
Reovirus infection usually has mild symptoms. Conjunctivitis, rhinitis, diarrhea, pneumonia may be present. More serious and rare complications are: encephalitis, respiratory tract irritation and tracheobronchitis. The virus has to be differentiated from other infectious agents causing canine viral enteritis and canine infectious tracheobronchitis. Diagnostic procedures include physical examination and complete blood profile, virus isolation, histopathology.
