Supplementary Figure 4: Temporal variation in the genomic variability of L. pneumophila strains.
From: Recombination drives genome evolution in outbreak-related Legionella pneumophila isolates
Nucleotide diversity (π filled dots) and population mutation rate (τ, unfilled dots) calculated for the core genome using Variscan (a) within and between the ST578 and ST637 strains grouped by outbreak or sporadic cases (sorted by the time at which each outbreak occurred) and (b) between the ST578 strains isolated in different years. Red represents the estimates in clinical samples (C), blue represents the estimates in environmental samples (E) and black shows the grouping of both together.
