Technical Abstract: Canine influenza virus (CIV) of the H3N8 subtype has emerged in dog populations throughout the U.S. where it has become endemic in kennels and animal shelters in some regions of the U.S. CIV is believed to be an equine influenza that was transmitted to and adapted to dogs. It has not previously been determined whether the canine adapted virus can be transmitted to chickens or turkeys which are susceptible to type A influenza virus from numerous species. Experimental studies were conducted to evaluate the susceptibility and pathogenesis of CIV in these species. The poultry species were inoculated with 105 50% Egg infectious doses per bird by the intra-choanal route. Clinical signs and gross lesions were absent in both species. Chickens and turkeys did not seroconvert. Oral and Cloacal swab material collected 2 day post inoculation were negative for virus.
