title: Fatal sepsis caused by an unusual Klebsiella species that was misidentified by an automated identification system.
abstract: This is a description of fatal sepsis caused by infection with Klebsiella variicola, which is an isolate genetically related to Klebsiella pneumoniae. The patient's condition was incorrectly diagnosed as common sepsis caused by K. pneumoniae, which was identified using an automated identification system, but next-generation sequencing and the non-fermentation of adonitol finally identified the cause of sepsis as K. variicola.
