Enterorrhagia Escherichia coli distributes regionally
Break out of our country enterorrhagia the intersection of Escherichia coli and O157H7 that decode all already recently the intersection of genome and message of the bacterial strain indicate, Chinese bacterial strain and U.S.A. and Japan break out bacterial strain to be different, break out with Germany difference of bacterial strain loud. It has geography nature characteristics that enterorrhagia Escherichia coli distributes this suggestion.
It was critical that O104H4 epidemic situation of spreading in Germany made the world see enterorrhagia Escherichia coli again. For many years, it is O157H7 to initiate in our country too and dissolve courageous and upright urine poisonous syndrome and enterorrhagia bacterial strain of the Escherichia coli dying. Center for Disease Prevention and Control of China (CDC) Infectious disease is prevented and cotrolled to chief researcher Xu JianGuo, introduced a few days ago, it was the blood kind that enterorrhagia Escherichia coli was infected with the excrement and urine of typical case, gain the name because of being able to cause patient's bleeding enteritis. Enterorrhagia Escherichia coli O157H7 has been infected with the case since in U.S.A.'s first discovery in 1982, this disease, in order to send one of the most critical number in infectious disease newly, has initiated and broken out the epidemic situation on a large scale in countries such as U.S.A., Japan, Canada,etc.. Our country find, have O157H7 infect 1986, about 20,000 people infect the epidemic situation of O157H7 on break out by the intersection of the South and some place 1999.
In recent years, prevent and cure science and technology under the great the intersection of project and subsidy in the intersection of country and infectious disease, China CDC infectious disease prevents and cotrols the research institute and cooperates with Taida biotechnology institute of Nankai University, have launched to the 1999 of our country O157H7 break out it is determined and analyzed that the genome of the bacterial strain prevailsed. Discover, the bacterial strain is typical enterorrhagia Escherichia coli that O157H7 of our country breaks out, with Escherichia coli of enterorrhagia nature the intersection of hemolysin and gene, will congratulate 1 toxin and will congratulate toxin 2 gene; Have the intersection of EAE and the intersection of virulence and gene and to break out bacterial strain 1993, 2006 such as U.S.A. of island and 1996 such as Japan break out bacterial strain to be similar. In addition of our country O157H7 break out bacterial strain fungus won a plasmid from sramana also, named as pO157_Sal. The bacterial strain genome that Japan, U.S.A. have already release been, there is not this plasmid. Find China, O157H7 of the United States and Japan break out bacterial strain to be very similar, have will congratulate 1 toxin, will, congratulate 2 toxin, hemolysin, the intersection of EAE and the intersection of virulence and the intersection of island,etc. and virulence gene relatively. But in the system studies the relation, Chinese bacterial strain and Japanese bacterial strain are a little nearer, stronger than American bacterial strain virulence.
Xu JianGuo says, for a long time, enterorrhagia Escherichia coli O157 and other countries of the German report are different to some extent. For example, enterorrhagia Escherichia coli O157 of China, the United States and Japan have H7 cilias more, the German bacterial strain does not have H7 cilia. The epidemic situation that O104H4 appeared suddenly this time breaks out, it is a first report of the world.
