Vibrio cholerae O1 El Tor and O139 Bengal Strains Carrying ctxBET, Bangladesh
Figure

Figure. . DNA fingerprinting patterns of Vibrio cholerae. Dendrogram was prepared by Dice similarity coefficient and UPGMA (unweighted pair-group method with arithmetic mean) clustering methods by using pulsed-field gel electrophoresis (PFGE) images of the NotI-digested genomic DNA. The scale bar at the top (left) indicates the correlation coefficient (range 90%–100%). V. cholerae altered ET (ctxBCL) strains (pulsotype A) formed a major cluster (cluster I), separated from prototype ET (ctxBET) strains (cluster II; pulsotype B) and V. cholerae O139 strains (cluster III; pulsotype C), suggesting that they are genetically different. ET, El Tor; Clin, Clinical; Env, environmental.
