FIG 1.

Phylogenetic tree of the 11 Acinetobacter GS 13BJ/14TU bloodstream isolates (isolates 1 through 11) from Chonnam National University Hospital and reference strains of Acinetobacter species from the GenBank database, constructed from 450-bp zone 2 sequences of the rpoB gene. This tree was inferred using the neighbor-joining method and a 1,000-replicate bootstrap analysis. The sequences tested in this study are underlined. New rpoB gene sequences (submitted to GenBank) identified in this study include accession no. KC138716 (isolate 1), KC138717 (isolate 6), and KC138718 (isolate 5). The scale bar indicates the number of base substitutions per site.
