| Popis: | The insertion sequence IS 629 , which is highly prevalent in Escherichia coli O157:H7 genomes, was found to be absent in O157:H− strains, which are on a divergent pathway in the emergence of O157:H7. Although O157:H− is deficient in IS 629 , it permits IS 629 transposition, with an excision frequency higher than that of ancestral O55:H7 strains but significantly lower than that of pathogenic O157:H7 strains. |
