Abstract
During the 2007 equine influenza outbreak in Australia, respiratory disease in dogs in close contact with infected horses was noted; influenza (H3N8) virus infection was confirmed. Nucleotide sequence of the virus from dogs was identical to that from horses. No evidence of dog-to-dog transmission or virus persistence in dogs was found.
Highlights
During the 2007 equine influenza outbreak in Australia, respiratory disease in dogs in close contact with infected horses was noted; influenza (H3N8) virus infection was confirmed
Testing of 19 dogs 2 years later showed no change in hemagglutinin inhibition (HI) titer, ELISA results were negative for each
Each seropositive dog had been in close proximity to equine influenza virus (EIV)-infected horses but not always in direct contact
Summary
During the 2007 equine influenza outbreak in Australia, respiratory disease in dogs in close contact with infected horses was noted; influenza (H3N8) virus infection was confirmed. Nasal swabs and serum were collected from each of the 40 dogs; 23 were seropositive according to influenza type A blocking ELISA [5] and hemagglutinin inhibition (HI) assay [5] using A/equine/Sydney/2007 virus as antigen (Table). Each seropositive dog had been in close proximity to EIV-infected horses but not always in direct contact. No evidence of lateral transmission was found for dogs that did not have contact with horses.
