Neighbor-joining tree after analyzing 273 nucleotides (91 variable) of the hsp60 gene of 206 study strains and 14 type and reference strains of the genus Enterobacter. The tree was rooted with the hsp60 sequence of E. aerogenes downloaded from GenBank (ENAE, accession number indicated). Type strains are labeled with T, reference strains with R, isolates from plants with a flower symbol, and isolates from animals with a picture of a dog. The animals from which strains were isolated are indicated after strain denominations, as are the abbreviations of the centers (see below) from which the strains originated. If several strains from one center had identical sequences, they were pooled at one spot of the tree, and the number of pooled strains is indicated after the center abbreviation. The scale gives the Jukes-Cantor distance along the branches. Numbers at the nodes of the tree indicate bootstrap values obtained after 100 replicates. A group of strains were considered a genetic cluster (I to XII) if the mean distinctness parameter k was above 2.0 (Table 3); otherwise it was called a sequence crowd (xiii). Cluster and sequence crowd denominations are indicated at the right side of the figure.
