A serological survey of canine respiratory coronavirus and canine influenza virus in Korean dogs.
The relationship between canine respiratory coronavirus (CRCoV) and canine influenza virus (CIV) seropositivity in dogs in Korea was examined. Sixty-two of the 483 samples (12.8%) were seropositive for CRCoV by indirect fluorescent antibody (IFA) analysis. Nineteen animals were seropositive for CIV by ELISA out of the 385 samples tested. Serum antibodies for both viruses were detected in 6 of the 483 dogs sampled, suggesting that these viruses are present in dogs in Korea. Although the role of CRCoV in canine infectious tracheobronchitis has not been fully elucidated, co-infection with CIV may synergistically worsen respiratory clinical signs and result in more severe canine tracheobronchitis.
