Klebsiella aerogenes: Introduction, Pathogenicity, Lab Diagnosis, Treatment, Prevention, and Keynotes

Klebsiella aerogenes growth on CLED medium after 48 hours of incubation

Introduction Klebsiella aerogenes (formerly known as Enterobacter aerogenes) is a Gram-negative, rod-shaped, motile bacterium belonging to the Enterobacteriaceae family. Whole-genome sequencing and comparative phylogenetics recently reclassified it into the genus Klebsiella because it is genetically closer to Klebsiella pneumoniae than to other Enterobacter species. It …
