Using tobacco virus to make FMD vaccine in China

Introduction: after repeated screening, Shanghai Institute of plant physiology and ecology, Chinese Academy of Sciences has made a new FMD vaccine with high safety by using tobacco virus Foot-and-mouth disease virus (FMDV) is a kind of virus that seriously affects the growth of meat and milk producing livestock all over the world Researchers at the Shanghai Institute of plant physiology and ecology found that pathogens that pose a threat to humans and animals do not infect plants, so they used plants as bioreactors to produce vaccines for humans and animals Researchers extracted a large number of TMV particles carrying fish 11 peptide and 14 peptide from tobacco, and made foot-and-mouth disease vaccine with them, and measured the immune efficiency of the vaccine in guinea pigs and suckling mice The experiment shows that this kind of antibody has immunity, which can stimulate a high level of neutralizing antibody in the immunized animals and resist the invasion of the virus In addition, researchers found that due to the weak infection ability of plant virus, even if the operation is inadvertently leaked to the natural environment, it will soon disappear Therefore, the safety of using tobacco as carrier to produce animal vaccine is much higher than that of traditional microorganism and animal cell reactor The researchers said it is a new technology with significant social and economic benefits, which can be used not only for livestock vaccine production, but also for the production of vaccines for human diseases, especially for oral use Because of the rapid growth of tobacco, the cost of using this technology is greatly reduced, and it can promote the diversified development of tobacco industry, and truly achieve the comprehensive processing and utilization of tobacco (author:) share to feed Weibo share to:
