Influenza virus gene's diversified panorama is drawn
It is reported ' Reporter Li TianShu) Recently, the scientific research personnel of our country drew the diversified panoramas of two important genes of influenza virus for the first time in the world. Through these panoramas, people can make a reservation in any poisonous positions in influenza virus family of influenza virus accurately, thus in order to resist person and many kinds of animal's epidemic diseases that this kind of virus caused, including people are infected with the great epidemic situation of first type H1N1 influenza virus at present, offer important technical support. It is reported, influenza virus can infect people, birds, pig, horse and some marine animals. Influenza virus is very complicated, according to 2 pieces of glycoprotein in its surface, influenza virus can be divided into 16 HAs to be inferior type and 9 NAs are inferior type, HA is inferior type several dozen are inferior type that the association that and NA is inferior type takes shape again, for instance H1N1, H3N2, H5N1,etc. are inferior type. Every inferior influenza virus is because of the gene between different and different poisonous one of time, geography, host " Hybridize " ,Have formed a very huge and complicated influenza virus family. This makes to define the position in the family of a certain influenza virus, judge its ins and outs is very difficult accurately. Chinese animal's hygiene and epidemiology centre researcher Chen JiMing group are since 2008, use 23000 gene sequences of computer network analysis during more than 4 months, have described the panoramas of panorama and NA gene of influenza virus HA gene for the first time in the world. Chen JiMing introduces, relies on these panoramas, researchers can define the position in the family of influenza virus of pig separated in each laboratory in recent years of China accurately, and affirmed some pig influenza viruses existing in the Chinese pig group are all ordinary pig influenza viruses.
