| Outline of Final Research Achievements |
The onset of mass outbreaks by pathogenic bacteria is needed to detect in their early stage for prevention of expansion. However, all of the patients observed in a certain period are not always derived from the same outbreak; therefore, it is necessary to investigate the relatedness of the organism isolated from several patients. This research conducted genome epidemiology, which can reveal the identity of several strains of a pathogenic bacterium by whole genome sequencing, for differentiating outbreak related enterohemorrhagic Escherichia coli O157 strains. The results of this study demonstrated that this approach is superior to previous methods. Additionally, some points to be careful to carry out genome epidemiology were elucidated.
