Klebsiella variicola QC Overview

Klebsiella variicola is a Gram-negative, facultatively anaerobic, encapsulated rod in the family Enterobacteriaceae, originally described as a nitrogen-fixing endophyte of plants and closely related to Klebsiella pneumoniae. It is increasingly recognised as a clinically relevant species responsible for bloodstream infections, urinary tract infections, and neonatal sepsis, and is often misidentified as K. pneumoniae by conventional laboratory methods. K. variicola can acquire carbapenemase and hypervirulence plasmids, and genomic studies have revealed distinct population structures adapted to plant, environmental, and clinical niches.
