Phylogenetic tree using ‘neighbor-joining’ algorithm on 16S rRNA gene sequences showing the relationship between
strain SD1D and related members of the genus
Escherichia coli ATCC 11775T (X80725) was used as an out-group. Bootstrap values (expressed as percentages of 100 replications) greater than 50% are given at nodes. Filled circles indicate that corresponding nodes were also recovered in the tree constructed with maximum parsimony and maximum likelihood. GenBank accession numbers are given in parentheses.
