The migratory bird has transmitted bird flu in Qinghai Lake
Through the continuous track of three years, the scientific research personnel of our country find, the poisonous one of bird flu separated in Qinghai Lake has been keeping the high analogy all the time, therefore the suggestion migratory bird will be probably serial H5N1 bird flu virus in Qinghai Lake " The spreading device " . Opened yesterday " China - Europe reproduces the infectious disease seminar newly now " Go, chief of Chinese Academy of Sciences institute of microbiology high the intersection of good fortune and researcher reveal, find while being above-mentioned, show Qinghai Lake series one very special the intersection of H5N1 and the intersection of bird flu and malicious one, there are important meanings in the reseach of vaccine of bird flu. From 2005 to 2007, the research group of the high good fortune carried on three - year long track in Qinghai Lake. Found finally, from poisonous one of H5N1 bird flu that is isolated in the body of migratory bird of Qinghai Lake in 2006 and 2007, very similar to 2005, only a few have happened smallly and made a variation. Meanwhile, researchers have not isolated similar bird flu virus from resident bird, the local poultry have not been infected with either. Then, researchers infer, serial H5N1 bird flu virus in Qinghai Lake will probably passed back through the migratory bird, the possibility that and the virus circulates in the Qinghai Lake part is relatively small. It is reported, there are eight migratory bird's routes of migrating in all in the whole world, three among them are closely related to bird flu happening in recent years. Time and easy inference of place according to breaking out, the activity of migrating of migratory bird propagates and plays a role in suring to bird flu. In addition, some biological characteristics support the above-mentioned view too. H5N1 poisonous passages that scientific research personnel will separate from the migratory bird of Qinghai Lake separate one from near Mongolian and Novosibirsk migratory bird to compare with finding, homologies of every passage are above 98%, reveal it may be closely related to series of Qinghai Lake that Mongolia separates one with H5N1 of Novosibirsk. The high good fortune thinks, except as the carriers and " travelling device "s of bird flu virus ,The wild migratory bird migrated to facilitate recombination of bird flu virus, became a natural enormous " storing device " of influenza virus ,Even " reactor " . So, in the same wild migratory bird's body, can measure to several kinds of existence of influenza virus sometimes. It is reported, the handing in of spring and summer of this year, researchers will continue monitoring the migratory bird in Qinghai Lake, in order to further confirm the role acted in the migratory bird propagates at bird flu.
