Bodewes, R; Egberink, H F

In this review, recent developments in the field of viral diseases of the dog and the cat are discussed. In the dog, infection with the coronavirus type 2 is associated with respiratory signs, while infection of a highly pathogenic strain of the coronavirus type 1 has been identified as the cause of mortality in puppies. A new strain of the canine parvovirus is identified, from which the pathogenicity is not yet completely clarified. Infection with West Nile virus is associated with progressive neurological disease and subclinical infections in dogs. Infection with equine influenza A (H3N8) or a highly related influenza virus can cause severe respiratory disease and mortality in greyhounds and other dogs. Infection with avian influenza A (H5N1) can cause disease and mortality in cats and is mostly subclinical in dogs. A number of outbreaks of highly virulent strains of the calicivirus in cats have been described.
