DNA microarrays and their application in detecting and identifying intestinal pathogens
基因芯片技术在检测肠道致病菌方面的应用

DNA microarrays offer many advantages of high throughout,automation,rapid detection,and so on.Therefore,this technology had been used in many fields such as molecular epidemiology of bacteria,microbial gene identification,disease mechanism,gene mutation,gene expression identification,DNA sequencing and medicine screening etc.The assays for identifying pathogens using DNA microarrays reported aboard recently are introduced.The application of DNA microarrays in detecting and identifying intestinal pathogens mainly includes three aspects: the identification of toxin and characteristic genes of pathogens,the identification of bacterial DNA or RNA directly,the simultaneous detection of a large number of intestinal pathogens with the target-gene of ribosomal RNA.Because of its high efficiency,DNA microarrays is superior to other biological method.Obviously DNA microarrays technology may be useful in identifying intestinal pathogens and have a wide prospect.
