ClonalFrame analysis of sequence types identified in human isolates and samples of surface waters from the rivers Mersey and Wyre (presented as a Consensus Network using SplitsTree). Genetic distance is indicated by the scale bar labeled 0.1. Most sequence types clustered into the three labeled clades, with the remainder labeled as “Intermediate.” Clade 1 (containing sequence types exclusively from human samples) is very tightly clustered at this scale, and detailed labeling is shown in the inset for clarity. All other sequence types shown were exclusively identified in water samples. The two most prevalent types in water samples grouped to the intermediate category and are shown in bold (ST-1766 and ST-1764).
