Figure 2From: Molecular diversity and high virulence of Legionella pneumophilastrains isolated from biofilms developed within a warm spring of a thermal spaLegionella pneumophila typing. The dendogramm represents the relationships of environmental and clinical strains of Legionella pneumophila. Patterns were generated by pulse field gel electrophoresis (PFGE) of total bacterial DNA and then clustered by unweighted pair group method with arithmetic averages algorithm.Back to article page
