Characterization of a Canadian mink H3N2 influenza A virus isolate genetically related to triple reassortant swine influenza virus.
Gagnon CA, Spearman G, Hamel A, Godson DL, Fortin A, Fontaine G, Tremblay D. - Service de diagnostic, Facult? de m?decine v?t?rinaire, Universit? de Montr?al, St-Hyacinthe, Qu?bec, Canada; Nova Scotia Department of Agriculture, Truro, Nova Scotia, Canada; Veterinary Diagnostic Services Manitoba Agriculture, Food and Rural Initiatives, Winnipeg, Manitoba, Canada; Prairie Diagnostic Services, Western College of Veterinary Medicine, Saskatoon, Saskatchewan, Canada.
In 2007, a H3N2 influenza A virus was isolated from Canadian mink. It was found to be phylogenetically related to a triple reassortant influenza virus which emerged in Canadian swine in 2005, but it is antigenically distinct.
The transmission of the virus from swine to mink seems to have occurred following the feeding of animals with a ration composed of uncooked meat bi-products of swine obtained from slaughterhouse facilities.
Serological analyses suggest that the mink influenza virus does not circulate in the swine population.
Presently, the prevalence of influenza virus in Canadian farmed and wild mink populations is unknown.
The natural occurrence of influenza virus infection in mink with the presence of clinical signs is a rare event that deserves to be reported.
