To develop and evaluate a platform that enables direct pathogen enrichment, identification, and antimicrobial susceptibility testing from whole blood at single-cell resolution.
Engineered the STREAM (sedimentation-assisted tandem rocking and enrichment for analysis and monitoring) platform to isolate live bacterial pathogens directly from whole blood near doubling times.
Integrated single-cell pathogen identification using molecularly barcoded sequential fluorescence in situ hybridization across 104 positive blood culture samples.
Conducted gel-based single-cell antimicrobial susceptibility testing across 219 drug-dose combinations directly from enriched samples.
Achieved 96.15% concordance with standard clinical laboratory identification across 104 positive blood culture samples.
Obtained 97.96% essential agreement and 93.9% categorical agreement for antimicrobial susceptibility testing across 219 drug-dose combinations.
Demonstrated an analytical limit of detection of 0.1 to 1 CFU/ml directly from whole blood, delivering complete diagnostic results in 6.75 to 17 hours.
