Klebsiella ornithinolytica (reclassified as Raoultella ornithinolytica) is a Gram-negative, encapsulated rod in the family Enterobacteriaceae, characterised by its ability to decarboxylate ornithine. It is found in aquatic environments, soil, and fish, and is an emerging opportunistic pathogen that can cause bacteraemia, urinary tract infections, and biliary sepsis, particularly in immunocompromised patients. The species possesses a chromosomally encoded class A beta-lactamase and shows notable genomic diversity in its accessory genome.

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.
