| genetic characterization of novel reassortant h1n2 influenza a viruses isolated from pigs in southeastern china. | in december 2004, three influenza h1n2 viruses were isolated from lung samples of pigs that had died from respiratory disease on a farm in southeastern china. to determine the genetic characterization and probable origin, one of the three isolates, a/swine/zhejiang/1/2004 (sw/zj/1/2004), was genetically analyzed. sw/zj/1/2004 was a reassortant with an na gene most closely related to the corresponding gene from a human-like h3n2 virus circulating in 1995. the remaining seven genes were most close ... | 2006 | 16755371 |
