Avian-to-human transmission of the PB1 gene of influenza A viruses in the 1957 and 1968 pandemics.

We determined the origin and evolutionary pathways of the PB1 genes of influenza A viruses responsible for the 1957 and 1968 human pandemics and obtained information on the variable or conserved region of the PB1 protein. The evolutionary tree constructed from nucleotide sequences suggested the foll...
