Abstract
Two strains of influenza A virus were isolated from pigs in northern J apan in 1992. Serological tests showed that the haemagglutinin (HA) an d neuraminidase (NA) antigens were more closely related to those of re cent human H1N1 viruses than to those of swine H1N1 viruses. The HA an d NA genes of isolate A/sw/Obihiro/5/92 were shown to be closely relat ed to those of current human H1N1 viruses. Evolutionary trees construc ted from nucleotide sequences showed that the HA and NA genes of A/sw/ Obihiro/5/92 were apparently on a branch cluster containing human stra ins isolated between 1990 and 1992.
