OBJECTIVES Achromobacter spanius is a newly described, non-fermenting, Gram-negative, coccoid pathogen isolated from human blood. Whole-genome sequencing of the A. spanius type strain was performed to investigate the mechanism of pathogenesis of this strain at a genomic level. METHODS The complete genome of A. spanius type strain DSM 23806T was sequenced using single-molecule real-time (SMRT) DNA sequencing. RESULTS The complete genome of DSM 23806T consists of one circular DNA chromosome of 6425783bp with a G+C content of 64.26%. The entire genome contains 5804 predicted coding sequences (CDS) and 55 tRNAs. Genomic island (GI) analysis showed that this strain encodes several important pathogenesis- and resistance-related genes. CONCLUSIONS These results strongly suggest that GIs provide some fitness advantages in A. spanius type strain DSM 23806T. This report provides an extensive understanding of A. spanius at a genomic level as well as an understanding of the evolution of A. spanius.
