Important achievements in avian influenza virus research in China have been published in authoritative journals

Introduction: Beijing, Aug 22 (Xinhua) - according to Beijing Evening News, the latest issue of science magazine published Professor Liu Jinhua of China Agricultural University as the first author, including researcher Gao Fu of Institute of Microbiology of Chinese Academy of Sciences, researcher Lei Fumin of Institute of zoology of Chinese Academy of Sciences, researcher Wang Jian of Institute of genomics and Professor Zhu Qingyu of Academy of Military Medical Sciences The latest research achievements in the research field are another world leading research achievements made by Chinese scientists in the field of avian influenza virus research The paper published in science, entitled "infection of H5N1 with highly pathogenic avian influenza to migratory birds", describes the situation of H5N1 highly pathogenic avian influenza infection among migratory birds in Qinghai Lake of China in the first half of this year In early May this year, a large number of migratory birds, such as spotted geese and brown headed gulls, died in Qinghai Lake, China The research team composed of experts from Agricultural University, Chinese Academy of Sciences, Chinese Academy of Medical Sciences and other research institutions went to the place of occurrence in time under the coordination of relevant government departments to carry out clinical diagnosis of dead migratory birds Through the study of serum antibody detection, virus isolation, identification and histopathology of collected samples, it was confirmed that the disease and death of migratory birds were caused by H5N1 subtype avian influenza virus infection It is the first time that a large number of deaths are caused by avian influenza in migratory birds The research team has carried out genome sequence analysis and Research on the characteristics of the virus It is preliminarily believed that the epidemic virus strain may be rearranged from several strains of influenza virus, or the virus strain has existed in nature for the first time and was discovered by scientists Further research results show that the pathogenicity of the H5N1 subtype avian influenza virus is much higher than that of the previous avian influenza virus, which suggests that people should pay more attention to the harm of migratory bird highly pathogenic avian influenza and its public health significance At present, although the exact source of the virus can not be determined, the occurrence of large-scale avian influenza in migratory birds also indicates that avian influenza is no longer a regional or national problem, but a problem that governments around the world must pay attention to.
