London, September 5 (Xinhua) ' The reporter is yellow) The magazine of Britain " natural medical science " publishes a latest research to say, American researchers research and develop a new kind of pulmonary tuberculosis vaccine, animal's experiment reveals it lies between the vaccine result better than the existing card. The researchers of American Einstein medical college transform through bacterium's gene, develop such new vaccine, and name it as IKEPLUS. Pulmonary tuberculosis is caused by branch bacillus of tuberculosis, the branch bacillus of tuberculosis has a " relative " Named the dirt branch bacillus of shame, they all have a gene which is called esx-3. Researchers find, if remove this gene in the dirt branch bacillus of shame, then plant into the same gene from branch bacillus of tuberculosis, the bacterium that gets finally can serve as vaccine. Animal's experiment reveals, on condition that infects with the branch bacillus of tuberculosis too, time has been 54 days that the experiment mouse not injecting any vaccine survived on average, time is 65 days that the experiment mouse injecting the card and lying between vaccine survives on average, and inject the surviving for time on average and is as long as 135 days of this new vaccine. Lead William Professor Jacob of this research to say, the function principle of new vaccine is different from already having vaccine of pulmonary tuberculosis, the experiment reveals it lies between the result of vaccine better than the card, researchers will develop vaccine that can be used for the human body on this basis.
