Avian influenza as the peptide biological antibody sector is a small company, we have to contribute to a thin edge, as a new generation of avian flu H7N9, H7N9 is a subtype of the avian flu. The outer membrane of influenza virus particles covered by two types of surface glycoprotein, a type hemagglutinin (H), a type of the neuraminidase (ie N), H is divided into 15 subtypes, N 9 subtypes . All human influenza virus can cause avian influenza, but not all of the avian influenza virus can cause human influenza, avian influenza virus, H5, H7, H9 can be transmitted to humans, including H5 highly pathogenic. Can be divided into HxNx 135 subtypes based on the characteristics of the influenza virus, H7N9 subtype of avian influenza virus is a past only found between poultry found no extraordinary circumstances of infection. The biological characteristics of the virulence of the virus, spread of power, there is no basis for the analysis and judgment.
In April 2013, issued by the Ministry of Health said that the H7N9 virus is sensitive to Tamiflu, initially identified using Tamiflu antiviral treatment, Influenza A, Avian H5N1A type influenza virus is a major public health threat in the United States each year caused by more than 30,000 people. The new influenza virus strains appear regularly to humans have little or no immunity, resulting in a devastating pandemic. Type A influenza can exist in a wide variety of animals, but it is in the birds, you can find all subtypes. Based on the classification of these subtypes of the virus coat glycoprotein hemagglutinin (HA) and neuraminidase (NA) subtypes. In 1997, the H5N1 avian influenza virus to determine the cause of death in 18 infected persons. There is some evidence that the human-human transmission of this virus, but it is considered to be the transmission efficiency is quite low. Already know the HA cleavage site and glycosylation patterns play an important role in determining pathogenic H5 avian influenza virus, it is only very recently that an additional glycosylation sites within the NA protein globular head also favor of highly pathogenic H5N1 avian influenza virus. Control near the carboxyl terminus of avian influenza A (H5N1) neuraminidase (1) I7649-49 synthetic peptide the corresponding to15aa peptide. Applications: suitable for antibody blocking. Other applications have not been tested. Recommended dilution: pre-adsorbed for 30 minutes, at 37 xA1C control: the 1UG peptide 1UG antibody. By the researcher to determine the optimum dilution. Storage and stability: can be stored in short-term the only 4 xA1C. For long-term storage should be stored at -20 xA1C. Is stable for at least 6 months -20 xA1C decile. In order to maximize the recovery of the product, after centrifugation of the original bottle to thaw before, please cap. May be further diluted in the assay buffer.
The new antibody vaccine requires the joint efforts of everyone.
China news agency, Beijing, April 4 (Reporter Ding Dong) - Chinese Ministry of Agriculture said the 4th National Avian Influenza Reference Laboratory at the date censorship from Shanghai Songjiang District, Shanghai Huai agricultural and sideline products wholesale markets dove samples detected H7N9 avian flu virus gene sequence analysis showed that the strains of low pathogenic avian influenza virus isolates were highly homologous with the H7N9 avian flu virus.
In view of the fact that the virus is a threat to the safety of human life, the Ministry of Agriculture decided to animals infected with the H7N9 bird flu virus temporarily into an animal disease management. Requirements of the relevant market in Shanghai to take strict measures for the prevention and control of animal diseases. Department of Agriculture requires the expansion of the H7N9 avian flu virus monitoring range, according to the monitoring results, to take further precautions.
Previously, many cases of human H7N9 subtype of influenza cases in Shanghai, Anhui, Jiangsu, Ministry of Agriculture sent a work team to three key provinces to carry out the the animal H7N9 outbreak investigation and epidemiological investigation. Once the H7N9 subtype influenza epidemic or virus in accordance with the "major animal epidemic emergency regulations" and "national emergency contingency plans for major animal epidemic will be in accordance with the relevant laws and regulations, immediately and decisively disposal.
