Canine influenza virus (CIV) is an emerging pathogen that causes severe and acute respiratory disease in dogs. In 2006, the H3N2 CIV was first identified in dogs from Guangdong province in China. The nine isolates were grouped together with the canine H3N2 viruses isolated from dogs and cats in Korea. The possible interspecies transmission of influenza A virus is very important. We carried out a sero-logical retrospective study using invited canine serum. The hospital invited 123 dogs, first vaccination group were revealed with CIV antibody positive rate of 81.8%. the second vaccination group were de-tected a positive rate of 91.2%. Antibody generation rate was higher in 3∼10 years dogs. Protective antibody titers were detected from 2 weeks to 12 months. thereafter below the protective antibody. The results indicate that H3N2 CIV may have been consistently circulating in dog populations. Recently. These findings showed that H3N2 CIV has the capacity to replicate in and transmit among cohoused dogs and underscore the need for continued public health surveillance. Considering the result continuous management and prevention system against CIV is required at the concentrated animal care centers. The importance of CIV surveillance in this region for understanding the genesis of this virus, and it is im-portant to remain aware of the potential of H3N2 CIV to be transmitted from dogs to the human population.
Abstract
