Use of pulsed-field gel electrophoresis for comparison of similar but distinguishable isolates of Shigella sonnei collected in Ireland and Italy

2006

ABSTRACT Comparison of pulsed-field gel electrophoresis patterns (generated with XbaI and BlnI) of Shigella sonnei isolates from Ireland and Italy suggests that two possibly distantly related lineages are present in both countries. Smaller, more closely related groups, including isolates from Ireland and Italy, were also noted. These groups raise the possibility that the dissemination of clonal groups of S. sonnei may have occurred in recent years.
