Our country sets up enterorrhagia Escherichia coli to measure the law fast
It is reported ' The intersection of reporter and Zheng dexterous) Recently, bacteriology scientist, biotechnology scientist of our country unite, set up enterorrhagia Escherichia coli O104H4 detection method and appraise the method fast, and already begun to popularize to the whole country. China CDC ( Center for Disease Prevention and Control) Infectious disease is prevented and cotrolled to chief researcher Xu JianGuo, claimed while accepting staff reporter's special visit a few days ago, the setting-up of this method, has offered the strong weapon for the fact that all parts of our country may catch invading this to have illness coming on originally newly in time. Xu JianGuo introduces, known common enterorrhagia Escherichia coli (EHEC) Serum type has 3: O157, O26, O111; The uncommon serum type has 40 multi-type. O104H4 of the epidemic situation is a kind of rare serum type in EHEC family to cause breaking out in Germany recently, contain the will and congratulate the toxin 2( vtx2a) Gene and intestines stick in Escherichia coli virulence plasmid at gathering 3 gene: aatA, aggR, aap. China CDC infectious disease has already to prevent and cotrol had a set of detection and qualification method that directs against EHEC-O157H7, also set up the detection method of the enteric gathering virulence plasmid which sticks Escherichia coli. Therefore, should study and set up and congratulate toxin 1, 2 to 4 genes (will of EHEC fast recently, hemolysin, EAE virulence island) , the gathering sticks aatA, aggR, aap3 a gene on Escherichia coli virulence plasmid to the intestines, and the detection method of O104 and H4 gene. The biotechnology institute Professor Wang Lei group and China CDC infectious disease of Taida of Nankai University prevent and cotrol, cooperate, have set up diagnosis serum which covers nearly 50 kinds of EHEC, and cover more than 10 kinds of Escherichia coli H (cilia) Diagnosis serum of the antigen, including O104 and H4. Meanwhile, set up PCR detection method that can measure O104H4 and diagnosed serum. It is reported, the detection method which two scientists' group sets up, not merely can find EHEC-O104H4 in time at present, also can find EHEC of the other serum type in time.
