Characterization of Shigella sonnei Isolate Carrying Shiga Toxin 2–Producing Gene
Figure

Figure. UPGMA dendrogram of XbaI restriction patterns of 2 Shigella sonnei isolates from a patient from Finland who became ill during a visit to Morocco. Genomic comparison of the 2 isolates was performed by using pulsed-field gel electrophoresis according to the standard protocol. The isolates showed 96% similarity, and a 3-fragment difference suggests that 1 isolate was a variant of the other. Scale bar represents % similarity. ial, invasion-associated locus; ipaH, invasion plasmid antigen H; invE, invasion gene transcription regulator invE; stx2, Shiga toxin 2.
