Phylogenetic analysis showed that the Canadian isolates cluster with other North American AIVs and are distinct from the Euro-Asian H5N1 isolates," scientists in Guelph, Canada report. "Individual gene comparisons demonstrated that the Ontario isolates were most similar to the viruses isolated from around the same time period and geographical area.
