Maximum parsimony trees generated from MLST, accessory and core genome data from Listeria monocytogenes strains. The maximum parsimony (MP) trees generated for the six Listeria monocytogenes strains F6900, 10403S, Clip81459, EGD-e, HCC23 and 4bF2365 using a) multi-locus sequence typing as described by Nightingale et al., 2005 [38]; b) the binary presence/absence data of the accessory genome found using the Panseq Core/Accessory Genome Analysis module with fragmentation size of 500 bp and sequence identity cutoff value of 85%; c) the aligned core genome found with the parameters of b). MP trees were created using Phylip v3.69 [43] with the PARS function. The inset table depicts the symmetrical tree distances between each pair of trees, calculated using the TREEDIST function of Phylip.
