Zhejiang H7N9 virus is an "outsider" migratory birds or culprit 08:34
About the sudden H7N9 virus, why this flu, "the source" East China About the possibility of human-to-human transmission will not occur, we all look forward to the laboratories and experts as soon as possible to solve the mystery.
Yesterday, the province virus experts, public health emergency monitoring key technologies in Zhejiang Key Laboratory Director Lu Yu, Ph.D., disclosed to reporters the latest research of the virus, and said that the H7N9 virus is likely to be the "outsider" wild birds brought over.
The reporter interviewed Dr. Wang Xiaodu, Agriculture and Forestry University, Wang Du that migratory birds may be the culprit this speculation to carry H7N9 virus, has some scientific truth.
Laboratory News:
H7N9 mutate, the virus may be the "outsider"
Yesterday, Zhejiang is the first case of infection with the H7N9 avian influenza virus in patients, the virus isolated strains. Laboratory personnel are on the virulence of the virus, characteristics, drug resistance. Currently separated from the H7N9 avian influenza virus, the expert opinion is the same: to reach the human future, not the large variability.
Virus experts in our province, Zhejiang public health emergency monitoring key technologies Key Laboratory Director Lu Yu, Ph.D., disclosed to reporters the latest research of the virus.
Playing with the virus for 30 years of dealings with Dr. Lu Yiyu tone from the computer virus gene sequencing chart, compared with the H7N9 virus in Shanghai, Anhui, a long string of sequencing, only a few marked in red letters suggesting that the small differences between the gene sequences.
LU Yi-yu said, very different viruses and bacteria, viruses must live in the body of cells and other living creatures in order to survive. So extract the strain of the virus, the virus actually "raising up", so they kept copy.
With years of experience, Lu Yi-yu to present their views, H7N9 avian influenza virus may be the "outsider".
Why do you say that? Lu Yi-yu said that this was because of the the H7 type the virus, before the birds in Zhejiang is relatively rare.
As early as 6-7 years ago, Lu Yi-yu has presided over a provincial Natural Science Foundation of China, "the impact of human and animal influenza recombinant human influenza research topics, and then want to access the H7 virus do research anywhere to be found in Zhejiang various relevant departments of the laboratory, not even the birds who also rare.
By virtue of this, Lu also stupid to think the H7N9 virus, including Zhejiang, including the Yangtze River Delta, it may be wild birds brought over the "outsider".
Agriculture and Forestry University, Dr. Wang Xiaodu confirmed:
Zhejiang domestic birds, not found before the H7N9 virus
Yesterday afternoon, the reporter to interview Dr. Wang Xiaodu Zhejiang Forestry University teacher, has long been engaged in the study of the disease in poultry experts.
He told reporters that H7N9 is not a new virus, not the first in the poultry. June 14, 2008, in Spain a teal samples, we found that the H7N9 virus.
He said that migratory birds may carry culprit is H7N9 virus this speculation has some scientific truth. The most likely route of transmission of migratory birds to poultry flocks, first transmitted from poultry to people.
The source of infection was the H7N9 locked in the spring migratory birds at rest in the Yangtze Delta.
First, it is a large number of migratory birds in the East China area lakes, the Hangzhou Bay, and the various ports, etc. rest area, with the recent discovery of the H7N9 avian flu virus, happen to coincide.
Secondly, from the genetics of viral nucleic acid analysis, the H7N9 gene fragments, H and N are from migratory birds, migratory birds and other wildlife and poultry body, and that the virus can indeed mutual communication.
However, the migratory birds is the culprit this speculation, whether correct or not, Wang Du, also need to be scientifically validated.
Wang Du told reporters the H7N9 virus, the main antigen gene H and N, where H has 16, N 9, the virus can have a variety of permutations and combinations, random reassortment occurs to produce a new virus, and this types of viruses in the evolutionary process, can easily mutate.
Earlier of H7N9 this virus in birds is rare, so no one has done in-depth study its pathogenicity. "I had in Zhejiang birds not seen H7N9." Wang Du said, "the more common H9N2, H5N1 and H7N7, especially after the two viruses in poultry of highly pathogenic, but there is no reports of these types of viruses. "
