Polymorphic Amplified Typing Sequences and Pulsed-Field Gel Electrophoresis Yield Comparable Results in the Strain Typing of a Diverse Set of Bovine Escherichia coli O157:H7 Isolates
Figure 2
Analysis of relatedness between the 25 bovine O157 isolates. (a) Dendogram for AvrII-based PATS profiles was constructed using the UPGMA option in the phylogenetic analysis using parsimony (PAUP; Sinauer Associates, Inc., Publishers, Sunderland, Ma.). (b) Dendogram for AvrII-based PFGE profiles was constructed using the UPGMA cluster analysis based on Dice coefficients performed in Bionumerics (Applied Maths, Saint-Martens-Laatem, Belgium). Percent tolerance used is shown above the dendogram.
