MAUVE alignments of L. monocytogenes genomes. Whole-genome alignments of L. monocytogenes isolates were carried out using MAUVE. Isolates are arranged by serotype, and genomes are displayed as locally colinear blocks (LCBs), which are labeled 1 to 6. Additional metadata for all strains are provided in Tables S1 and S2 in the supplemental material. The isolates used for this figure are as follows, with the original identification and serotype in parentheses: BCW_2992 (J1776, serotype 4b), BCW_2993 (J1817, serotype 4b), L1846 (serotype 1/2a), L2624 (serotype 1/2b), L2625 (serotype 1/2a), L2676 (serotype 1/2a), BCW_2360 (C1-387, serotype 1/2a), BCW_2366 (J2-064, serotype 1/2b), BCW_2410 (N1-011, serotype 1/2b), BCW_2398 (J2-031, serotype 1/2a), BCW_2377 (J2-1091, serotype 4b), BCW_2358 (R2-502, serotype 1/2b), BCW_2994 (J1926, serotype 4B), L2074 (serotype 1/2a), and L2626 (serotype 1/2a).
