Canine respiratory coronavirus: an emerging pathogen in the canine infectious respiratory disease complex

Kerstin Erles et al. Vet Clin North Am Small Anim Pract. 2008 Jul.

Abstract

Infectious respiratory disease in dogs is a constant challenge because of the involvement of several pathogens and environmental factors. Canine respiratory coronavirus (CRCoV) is a new coronavirus of dogs, which is widespread in North America, Japan, and several European countries. CRCoV has been associated with respiratory disease, particularly in kenneled dog populations. The virus is genetically and antigenically distinct from enteric canine coronavirus; therefore, specific tests are required for diagnosis.

Phylogenetic tree based on the partial polymerase gene sequence of coronaviruses. Gray shaded areas show the separation into groups 1 to 3. CRCoV is situated in group 2 with the most closely related species, BCoV, human coronavirus strain OC43 (HCoV-OC43), and porcine hemagglutinating encephalomyelitis virus (HEV), in addition to murine hepatitis virus (MHV) and rat sialodacryoadenitis virus (SDAV). Group 1 contains enteric CCoV, porcine transmissible gastroenteritis virus (TGEV), feline infectious peritonitis virus (FIPV), and human coronavirus strain 229E (HCoV-229E). Group 3 contains the avian coronaviruses infectious bronchitis virus (IBV) and turkey coronavirus (TCoV). Severe acute respiratory syndrome (SARS) coronavirus is currently classified as part of group 2 but may be reclassified as a new group 4 with related bat coronaviruses.
