Comprehensive analysis of microorganisms in severe septic patients in the intensive care unit by mNGS and microbial culture

Detection of predominant pathogenic microorganisms or particular bacteria in the sputum or BAL samples by mNGS are associated with poor clinical outcomes among severe septic patients in ICU in this cohort. The high prevalence of multidrug-resistant bacteria among these patients underscores the importance of integration of mNGS with antimicrobial susceptibility assessment in the clinical practice to develop the most effective treatment regimens.
