Ultra-Rapid Drug Susceptibility Testing for Klebsiella pneumoniae Clinical Isolates in 60 Min by SYBR Green I/Propidium Iodide Viability Assay.

ABSTRACT:

Background

We aimed to optimize and validate the drug susceptibility test (DST) assay by SYBR Green I/PI (SG-PI) method using a panel of 89 Klebsiella pneumoniae clinical isolates in comparison with the conventional DST method to three most important antibiotics used for treatment of this bacterial infection, including imipenem, cefmetazole, and gentamicin.

Methods

By staining with SYBR Green I and PI dyes, green fluorescence and red fluorescence, which linearly correlated with the percentages of live and dead or membrane damaged cells, respectively, were used to produce two standard curves to calculate the relative cell membrane impermeable rates for each log and stationary phase cultures. Stationary phase K. pneumoniae cells were used in imipenem and cefmetaz
