Infect in the courtyard " The chief culprit " Succeeded in following the trail of
It is reported (reporter Li TianShu) Able to bear golden yellow staphylococcus (MRSA) of west forest of first oxygen Spread all over the world during nearly half a century, it is " chief culprit " that infects in the courtyard . How is this spread route which is able to bear the medicine bacterium? Latest Science published on January 22 has reported one dose of an achievements of research institute of institute of mulberry of British Cambridge University Wellcome foundation. The new gene order-checking technology of researcher's first application, have delineated out the pedigree picture of this bacterium, and succeed in following the trail of MRSA, thus offer support for infecting the control strategy in the courtyard.
After penicillin came out in the forties of last century, the infective disease that golden yellow staphylococcus caused got greater control, but with the mass use of penicillin, some golden yellow staphylococcus begins to be able to bear medicines. In 1961, Britain found able to bear golden yellow staphylococcus of west forest of first oxygen at first, this bacterium was found in medical organizations from all parts of the world in succession subsequently. Our country began the report related to this bacterium in the seventies of last century initially, this bacterium becomes one of the important pathogens infected in the courtyard nowadays, not merely threaten the security of the patient's life, more thorny too on treating.
In recent years, the bacterial strain that researchers are finding MRSA new constantly, is briefing on this bacterium to make a variation constantly. Sketch the contours of the evolution relation between different bacterial strain accurately, supervise the route that the bacterial strain spreads, researcher of one dose of research institutes of institute mulberry of British Cambridge University Wellcome foundation is with the method of checking order of the gene, draw every the unit from different MRSA bacterial strain genome to click. Scientific research personnel found and belonged to one and is called " ST239 " in the hospital most common MRSA at present 63 MRSAs of the population. The bacterial strain is able to bear nature to antibiotic, probably have 2/3 of the samples come from gathering from 1982 to 2003, in that 1/3 of the samples come from some patients of hospital in Thailand. Researchers, through analyzing the hereditary variation situation among samples, succeed in drawing out the pedigree picture. The pedigree picture has revealed " ST239 " How to spread to different areas of the world, and in the course of spreading, how new variation is taking place constantly, thus further evolve and produce the similar bacterial strain on science of heredity.
Researchers have followed the trail of an incident that MRSA infect breaking out happening in one hospital ICU ward of London, the discovery is a bacterial strain from Southeast Asia. The researchers of one dose of research institutes of institute of mulberry point out, through following the route that MRSA spreads among different medical organizations, can monitor the emerging bacterial strain effectively. It is helpful for this research to control infecting the measure in making the hospital.
