Synteny plot of the chromosomes of L. pneumophila strains Paris, Lens, Corby, and L. longbeachae NSW150. The plot was created using the mummer software package. (A) Synteny plot of the chromosomes of strains L. pneumophila Paris and Corby (B) and strains L. pneumophila Paris and Lens and (C) strains L. pneumophila Paris and L. longbeachae NSW150. Inversions between the genomic sequences are represented in blue. Genome-wide synteny is disrupted by a 260 kb inversion (blue) and a 130 kb plasticity zone between strain L. pneumophila Paris and Lens. In contrast, synteny between L. pneumophila and L. longbeachae is highly conserved.
