OXA-258 from achromobacter ruhlandii: A species-specific marker

Abstract

A new blaOXA-258 gene is described as a species-specific taxonomic marker for Achromobacter ruhlandii isolates (all recovered from cystic fibrosis patients). Even though OXA-258 differs from OXA-114 variants, isolates could be misidentified as A. xiloxosidans by the amplification of an inner fragment from the OXA-coding gene. A robust identification of A. ruhlandii can be achieved by sequencing this single OXA gene, as well as by a more laborious recently proposed multilocus sequence-typing (MLST) scheme.
