Domestic canaries (Serinus canaria forma domestica) are susceptible to Low Pathogenic Avian Influenza virus infections.

Domestic canaries (Serinus canaria forma domestica) are susceptible to Low Pathogenic Avian Influenza virus infections. Avian Pathol. 2018 Sep 12;:0 Authors: Marché S, van den Berg T, Lambrecht B Abstract Avian influenza viruses have been isolated from many bird species; however, little is known about the susceptibility of pet birds to low pathogenic avian influenza (LPAI) viruses. To address this research gap, domestic canaries (Serinus canaria forma domestica) were experimentally infected with H5 and H7 LPAI viruses to determine susceptibility and evaluate samples for diagnostic purposes. Clinical evidence of infection (eg, ruffled plumage and apathy) and mortality were noted for the canaries inoculated with chicken adapted LPAI viruses. Real-time reverse transcription-polymerase chain reaction (RRT-PCR) demonstrated higher viral RNA levels in buccal compared to faecal samples. No clinical symptoms or mortality were observed in canaries inoculated with LPAI virus originating from wild birds; however, the canaries in this group did have evidence of viral RNA in buccal and faecal samples. Overall, this study showed that domestic canaries are susceptible to LPAI virus infections and that they can shed large amounts of viral RNA, primarily through the respiratory route. Thus, buccal swabs might be better samples than feces for efficient detection of some LPAI virus infections in these birds. Although canaries have not been identified ...
