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 …

Detecting Low-Yield Target Fungal DNA from Bronchoalveolar Lavage Fluid: Sensitivity Limits of Conventional vs. Quantitative PCR

Detecting Low-Yield Target Fungal DNA from Bronchoalveolar Lavage Fluid: Sensitivity Limits of Conventional vs. Quantitative PCR

Introduction 0.5 ng/µL of DNA is detectable and can yield a positive result by PCR. In modern molecular diagnostics, PCR is incredibly sensitive. While 0.5 ng/µL might seem like a low concentration on a spectrophotometer (like a NanoDrop), it is actually a substantial amount of …
