[Evolution and epidemiology of influenza A viruses].

Nihon rinsho. Japanese journal of clinical medicine - 1 Oct 1996

Nakajima S, Nobusawa E, Nakajima K

Abstract excerpt

Influenza A viruses are suitable for the analysis of virus evolution because the genes of the viruses are well analyzed. The origin of the present human influenza A viruses are deduced to be direct descendent of the viruses which caused Spanish flu in 1918. The analysis of NS gene shows the branching point between avian and human viruses are early 1900. By comparison of the amino acid sequences, HA serotypes...
