Phylogenomic reconstruction of 26 L. monocytogenes strains. (A) Neighbor joining (NJ) tree based on the presence or absence of 3,560 HGs in 7 LI, 9 LII and 10 LIII genomes. EGD-e and J2-071 are analyzed by both BLAST and CGH data. Braches with bootstrap (1,000 replicates) values less than 70% were labeled in red. (B) NJ tree based on the presence or absence of 2,855 EGD-e core genes. (C) Split network based on the distribution of 3,560 HGs in 26 L. monocytogenes genomes.
