Abstract

Canine respiratory coronavirus (CRCoV) from the beta-coronavirus family, has been described worldwide and is most commonly associated with the early stage of CIRDC (Canine infectious respiratory disease complex). The main CRCoV multiplication site is the respiratory system, so it is assumed that the virus spreads through the excretions of the respiratory tract. Places with a large number of dogs, such as animal shelters, dog shows and similar, contribute to the spread of the virus.
Nasal and pharyngeal swabs of 258 dogs were screened during this study. Amongst them, 68 had clinical signs of respiratory disease. Out of 258 dogs, 88 of them were from shelters for neglected animals, while the rest belonged to private owner. Reverse transcription polymerase chain reaction (RT-PCR) was used to confirm the presence of CRCoV.
CRCoV was detected in 3.87% of the examined dogs. There was a significantly higher rate of infection in dogs from the animal shelters compared to privately owned dogs, while gender and age did not have a significant influence on RT-PCR test results. Interestingly, CRCoV was detected more frequently in dogs without clinical signs of respiratory disease, which leads to the conclusion that CRCoV is not significant as an independent cause of respiratory diseases in dogs, or CIRDC.
