Cultivation and Genomic DNA Extraction of Klebsiella pneumoniae

Abstract

AbstractKlebsiella pneumoniae is a Gram‐negative, rod‐shaped bacterium of medical significance. It typically exists as part of the normal flora of the human intestine but can cause severe infections in the healthcare setting due to its rapid acquisition of antibiotic resistance. Cultivating and extracting genomic DNA from this bacterium is crucial for downstream characterization and comparative analyses. To provide a standardized approach for growing K. pneumoniae in the laboratory setting, this collection of protocols provides step‐by‐step procedures for routine culturing, generating growth curves, storing bacteria, and extracting genomic DNA. © 2024 The Authors.
