HIGH RESOLUTION TYPING SYSTEM FOR PATHOGENIC E. COLI

摘要

Variable number tandem repeat (VNTR) sequences have been identified in the genome of certain E. coli O157:H7 strains. It has been discovered that the VNTR sequences exhibit length polymorphism at different loci. A sub-typing system based on multiloci size analysis of VNTR is the basis of the novel molecular sub-typing system of the present invention.
