Figure. . Maximum-likelihood tree based on the concatenated sequences (3,036 bp) of the 7 multilocus sequence type (ST) loci for Cronobacter isolates. The tree was drawn to scale by using MEGA5 (www.megasoftware.net), with 1,000 bootstrap replicates. Numbers on branches indicate percentage of bootstrap values. Scale bar indicates nucleotide substitutions per site.
