Figure 1. 16S rDNA tree showing relationship of isolates 1 to 5 with related alpha- and beta-proteobacteria. The tree was constructed by using the neighbor-joining method, based on the nearly complete sequence (1,289 nt) of the 16S rDNA gene. Bootstrap values resulting from 100 replications are at branch points. Staphylococcus aureus was used as an outgroup.
