Figure. NotI-digested pulsed-field gel electrophoresis (PFGE) profiles of Vibrio cholerae isolates, Laos, 2010. The names of the profiles and the sources of the isolates are shown on the right. A dendrogram was created with BioNumerics software (Applied Maths, Kortrijk, Belgium) by using the Dice coefficient, unweighted pair-group method with arithmetic means, and a band-position tolerance of 1.2%. Arrowheads at bottom indicate location of bands differing in PFGE-A and PFGE-B.
