,giuseppe zanotti<p> H7 subtypes of highly pathogenic and low pathogenic virus into two kinds, which is pathogenic for poultry in terms of. For H7N9, the initial judgment is low pathogenic avian in nature,abercrombies, and therefore may be the case, although infection in poultry or wild birds but not disease. Guo view, low pathogenic and highly pathogenic mainly determined by the HA, HA exists in the connection of carbon,louboutin noir, if the connection in a string of basic amino acid carbon is generally highly pathogenic. If only one,abercrombie paris, it is low pathogenic. "It's only one." Of course,tn nike pas cher, he thought it was not absolute. Guo also think that there will be no indication that H7N9 infection among humans situation. Jin Qi believes that if the virus from person to person determined by the viral genes affected by many factors. Regardless of whether it is bird flu virus, a virus can spread from person, depending on the host cells can allow the virus to enter and copy propagation. Chinese Center for Disease Control, said the relevant information, since the species barrier, the bird flu virus only in occasional cases can infect humans. This statement, Guo think it is still unable to determine that occasionally in the end is what? H7N9 why suddenly infect humans. He believes that the current case does not exclude infection own immune system problems. Bulk distribution of cases presented, close contacts of cases have been isolated Shanghai ended, did the disease. Guo opinion, H5N1 has also been infected, but has been in the past ten years, the situation of human to human transmission has not occurred. "It can be said to some extent.</p>
<p> H5N1 infected person's own immune system or because of a problem with the gene." Guo said. But all this is just speculation. The only certainty is that there are still too many unknown viruses. Jin Qi said that for a living body, it takes a lot of time to explore,chaussures louboutin homme, "is just a one of the clues we now have." � Beijing News chief correspondent reports from Beijing Zhang Han (Original title: The new H7N9 avian influenza virus Secret) (EdiCentral enterprises, Wang Qishan here!

<p> which is the constellation effect genes - genes as rich as the stars in the sky, each star will play a role - and therefore can not quickly determine a new virus toxicity and ability to communicate the body. After the virus reassortment toxicity nor change the law. Speaking from virology,nike france, viral change is in order to facilitate their own survival. From an evolutionary point of view,louboutin femme pas cher, the toxicity should not be getting stronger. Toxicity becomes stronger, the host dies quickly, the virus will not be able to reproduce. Typically virus should be a weakening trend. But in individual reassortment, the "enhancement, weakening are possible." Prior to infect humans, H7N9 has infected poultry or whether livestock has been no definite statement. Previously, China has not isolated H7N9,peuterey 2015, also known as the Ministry of Agriculture was not in live bird markets in and around the poultry and pigs, animals detected H7N9 subtype of influenza A virus. But yesterday,louboutin femme pas cher, he said the information released by the Ministry of Agriculture, has found the virus from Shanghai's pigeons. Gene sequences showed that the strain is low pathogenicity influenza virus, isolates highly homologous with human avian influenza virus H7N9. Leading technology journal "Nature" magazine (Nature) recently issued a document that genomic analysis of this new virus showed that it could spread in poultry quietly without causing a serious disease,air max, which makes the virus very difficult to monitor. Guo believes.</p>
<p> In 1902,moncler outlet, H7N7 outbreaks in poultry once. In 2003, H7N7 had led to 80 people being infected. In this sequence, the infection has been extraordinary also include H7N2, H7N3. In addition there is a death, the other more minor symptoms of conjunctivitis and other diseases. H7N9 had been found in 25 strains, but the situation did not occur to infect humans. Ministry of Agriculture statistics, 25 strains were derived from wild birds. H7N9 from undetected even in China, more than 25 strains of all the data from the foreign research institutions. 1977 began to engage in the study of bird flu in the country has never been separated Guo Xing experts had H7N9. To his knowledge, the United States had isolated H7N9, and doubt that it can spread in ferrets, the ferrets is a mammal, closer to humans than birds. Overall, in the family H7 subtypes in poultry H7N9 did not show a strong destructive power. Similarly, H9N2 and no deaths caused precedent. A man, a self Experts found the first international H9N2 can infect people and people sick. In his view,hollister 2015, H9N2 is characterized by relatively wide host, in humans, pigs, and chickens have all been isolated, and its receptor, a little closer to mammalian receptors. Many veterinarians can detect the serum H9N2 antibodies. This spring,barbour 2015, China has 14 people infected H7N9,5 deaths. More reminiscent of the H5N1 bird flu virus cases H5N1,1997 death,nike pas cher, once menacing. In the clinical manifestations, the two have similarities - fast onset, lung disease and high mortality. But experts said that at present have not found H5N1 and H7N9 relevance. Can H7N9 infection among people? Experts believe that if the virus from person to person by a virus decide genes affected by many factors For people infected with H7N9, China CDC said, because the study limited information currently unable to make accurate judgments of the virulence and interpersonal communication ability of the virus. Experts said the man, a self,louboutin, a virulence of the virus is determined by the whole genome.</p>
