Phylogenetic relationships of lacIZY for Salmonella isolates and other Enterobacteriaceae. This neighbor-joining tree was constructed using the Kimura two-parameter model of nucleotide substitution. Bootstrap values based on 500 replications are given at the internal nodes. Salmonella isolates are indicated by the black circles and bold text. The branch connecting the S. enterica subsp. arizonae/diarizonae cluster with the rest of the isolates was shortened to improve the clarity of the relationships and its actual length is given above the dashed line
