South China Agricultural University, south of the Five Ridges modern agricultural science and technology Guangdong provincial laboratory professor Shen Yongyi, Xiao Lihua and other researchers, through joint research, New Coronavirus's potential intermediate host in the source of a breakthrough. Their latest research shows that pangolin is the potential intermediate host of New Coronavirus.
At 7 a.m. on 11, South China Agricultural University held a forenoon press conference on New Coronavirus's pneumonia epidemic.
It is understood that the team tackled more than 1000 metagenomic samples and identified pangolin as the potential intermediate host of New Coronavirus. Then the & beta; The positive rate of coronavirus was 70%; The virus was further isolated and identified, and the typical coronavirus particle structure was observed under electron microscope; Finally, through the genome analysis of the virus, it was found that the sequence similarity between the isolated virus strain and the current human infected virus strain was as high as 99%.
Research experts say that coronavirus can infect people only through an intermediate host. For example, the source of SARS virus is bats, but only through civet cats to infect humans, the intermediate hosts play a bridge role between pathogens and humans.
Experts believe that the outbreak of COVID-19 pneumonia in winter, but bat in winter hibernation, concentrated in the cave, the possibility of direct infection of human beings is very little. Therefore, the intermediate host may be the source of infection of the virus.
In terms of virus protection, if the source of infection is not controlled, even if the isolation and protection in the middle is done well, the epidemic situation is difficult to be controlled and prone to recurrence.
Professor Liu Yahong, deputy director of Guangdong Provincial Laboratory of modern agricultural science and technology and President of South China Agricultural University, introduced the outbreak of 2019-nCoV New Coronavirus in early to effectively respond to the epidemic situation and enhance the ability of science and technology control and prevention. South of the Five Ridges modern agricultural science and Technology Laboratory of Guangdong province and South China Agricultural University attached great importance to it, under the guidance of various government departments in Guangdong province. Under the support of Guangdong agricultural and rural department, New Coronavirus epidemic prevention and control science and technology emergency response special topic, we integrate the advantages of academic disciplines platform, organize the school advantage research force, launch joint prevention and control of epidemic situation, and make a major breakthrough.
Liu Yahong said, "in view of the seriousness of the current epidemic prevention and control, we chose to publish the research results to the public at the first time, hoping to contribute to the scientific prevention and control of the epidemic and provide reference for more scientists to carry out further work."
Liu Yahong said that the school will take the power of the whole school, give full play to the platform of South of the Five Ridges modern agriculture science and technology, Guangdong laboratory and so on, and be bold in taking the initiative to take the initiative to pay close attention to the possible impact of New Coronavirus on livestock and poultry industry and agricultural production, and to strengthen the monitoring and research of animal epidemic diseases and animal origin zoonosis.
