Fig. 3From: Comparative genomics analyses revealed two virulent Listeria monocytogenes strains isolated from ready-to-eat foodSNP-based phylogeny tree of 17 Listeria strains. The phylogeny tree was generated using CSI Phylogeny 1.4 [19]. Single nucleotide polymorphisms (SNPs) of each strain were called by mapping the genome sequence to that of the reference. The quality-checked SNPs were then concatenated and used to infer a maximum-likelihood tree. The “Reference” refers to the Reference strain L. monocytogenes EGD-eBack to article page
