Porcine respiratory coronavirus PRCV is present in many countries, including Canada, but controversy still exists concerning its pathogenicity. Two contact piglets were kept with the inoculated animals.

Three animals served as control. Polypnea and dyspnea coronabirus the main clinical signs observed. Diffuse bronchioloalveolar damage occurred 24 hours postinoculation. Changes compatible with bronchointerstitial pneumonia were present six days postinoculation. The inoculated virus was recovered from the respiratory tract and mesenteric lymph nodes, but not from the digestive tract, of the inoculated as well as the contact piglets.
No virus was isolated from the control piglets. The development of clinical signs and histopathological changes in inoculated as well as in contact piglets and the reisolation of the inoculated virus demonstrated that Poricno can be an important respiratory pathogen.
