Achromobacter xylosoxidans is a non-fermenting Gram-negative rod within the order Burkholderiales, commonly found in water, soil, and moist clinical environments. It is increasingly recognised as an opportunistic pathogen, particularly in people with chronic lung conditions such as cystic fibrosis, and can cause pneumonia, bloodstream infections, and device-associated outbreaks. Genomically, A. xylosoxidans displays high diversity with an open pangenome, extensive accessory content, and notable environmental adaptation traits.
Derived from 415 genomes: 28 from RefSeq and 387 from other sources. For the derivation pipeline and the PASS / WARN / FAIL verdict model, see the methods page for qualibact-v1.1.
QualiBact qualibact-v1.1 thresholds for Achromobacter xylosoxidans, derived from an expanded reference set that brings in additional A. xylosoxidans genomes beyond the AllTheBacteria-2024-08 distribution used for v1.0.
Threshold derivation, outlier detection, and PASS / WARN / FAIL verdict logic are unchanged from v1.0. See the methods page for qualibact-v1.1 for the engine pipeline and what differs between v1.0 and v1.1 overall.

How to read this: A value outside a failure limit fails QC. Within the failure limits, values beyond a warning limit are borderline and worth a manual look; values within the warning limits pass that criterion. A dash means that no bound is defined on that side.
