Dog to dog transmission of a novel influenza virus (H5N2) isolated from a canine.
In 2009, an influenza virus (IV), A/canine/Shandong/JT01/2009 (CA/SD/JT01/09), was isolated from the dog exhibiting respiratory signs in China, and was a novel H5N2. Intraspecies transmission of the virus in dog population had thus far remained unclear. To determine whether the novel H5N2 was transmitted among dogs, we conducted contact exposure and inoculation experiments. Susceptible dogs were housed in the room which the novel H5N2 infected dogs were housed in. As a result, the direct contact resulted in intraspecies transmission. Most of the infected dogs and the sentinel animals developed mild respiratory syndrome, including transient increased body temperatures, conjunctivitis, sneezing, nasal discharge and mild coughing, virus shedding and seroconversion, but no fatal disease. These data suggest that dogs may play a role in transmission and spread of influenza virus.
