I scientist find good fortune will congratulate the intersection of fungus and new fungus type for the first time
It is reported ' The intersection of reporter and Zheng dexterous) The scientist of our country discovers recently, initiate the will to congratulate the etiology of fungus dysentery in our country, has already no longer 2a will of good fortune congratulated the fungus, it is a kind of new fungus type - -Congratulate the fungus in good fortune Xv will. The expert points out, this discovery means our country has had now dysentery would that congratulated vaccine of fungus to already lose and use the meaning. The clinical microbiological magazine that the American microorganism published on February 1 learns publishes the relevant research report. Head the list of signers in Center for Disease Prevention and Control of China (CDC) of this research Infectious disease is prevented and cotrolled to chief Xu JianGuo and introduced, bacillary dysentery is mainly congratulated by the will it is caused that the fungus was born in the year of bacteria, it is estimated that 165 million persons infect the will and congratulate the fungus every year in the whole world, the death toll is up to 700,000. The fungus is pathogenic and extremely strong that the will is congratulated, 10 bacteria cell can make the person have illness coming on. React according to biochemistry and O antigen is different, will congratulate fungus belong to can divide into 4 the intersection of serum and group ' Namely dysentery will congratulate fungus, good fortune will congratulate fungus, Bao will congratulate fungus, inner will Song congratulate the fungus) . Think will congratulate the intersection of fungus and dysentery congratulate by the intersection of 2a and will by good fortune mainly fungus cause, vaccine of fungus is directed primarily to this fungus type to produce the will used and congratulate both at home and abroad. In 2001, Henan Province CDC report found a kind of will and congratulated the fungus new serum type, the separating rate exceeded the good fortune 2a, becoming for 5 years in succession should save the first advantage serum type. Use existingly and diagnose serum, is identified as the good fortune 4c. Thereafter, China CDC infectious disease prevents and cotrols, discovers with Henan Province CDC cooperation, this new serum type bacterial strain is not the good fortune 4c. To the further analysis of array of this genome, have found the code X serum type antigenic gene, and different from antigen of X of good fortune, it is a mutation. The scientist names this bacterial strain as Xv will of good fortune to congratulate the fungus. Discover thoroughly, the virus that the gene which encodes X serum type antigen lies in a bacterium - -On the phage. After obtaining this phage, researchers construct in the laboratory out Xv bacterial strain of a good fortune manually, the phenomenon that observes has appeared in the nature repeatedly. Phage transfer to lead, can vary serum type constantly, evade the specific immunity that crowd set up to protect. Xu JianGuo claims, the will is congratulated it has serum type specificities, vaccine prepared with a kind of serum type bacterial strain that the fungus immunity is protected, can only protect the infection that the same serum type bacterial strain causes. So, the aforesaid discovers that means our country has had now dysentery would that congratulated vaccine of fungus to already lose and use the meaning. Will congratulate dysentery of fungus prevents from the control strategy and need be revitalized. Study, find good fortune the intersection of Xv and will congratulate fungus able to bear nature, strengthen to antibiotic, among them to to able to bear nature and close 100% penicillin still. It is reported, while congratulating 46 serum types of fungus in the known will, only the good fortune Xv serum type was found and named at first by the scientist of our country.
