Whole-genome alignment of the L. crispatus genomes. The contigs of the draft genomes were ordered with MAUVE using the ST1 genome as a reference. Matching genome regions were identified with BLASTN and visualized using the Artemis Comparison Tool (ACT). Vertical bands represent the BLASTN matches (bit score ≥ 1500). Prophinder-predicted prophage-like genomic regions and IslandViewer predicted GIs are represented as blue boxes on the bottom and red boxes on the top strand of each genome, respectively.
