Fast blood test to quickly find bloodstream bacteria and the best antibiotics
Integrated genotype-informed single-cell molecular antibacterial susceptibility testing platform for rapid and actionable diagnosis of bacteremia
This project is creating a fast blood test that finds bacteria in the blood, identifies the species, measures how many are present, and shows which antibiotics are likely to work for people with suspected bacteremia.

What this research studies
Imagine a blood test that finds bacteria directly without waiting for slow cultures. It would identify the bacterial species, measure how many bacteria are present, and use single-cell methods to show which antibiotics are likely to work. The platform is built to be flexible so your clinician can choose which bacteria and drugs to test depending on your situation. The aim is to give clear, actionable results much faster than current culture-based methods.
Who could benefit from this research
Good fit: Ideal candidates are people with suspected or confirmed bacteremia or sepsis who can provide blood samples during acute care, typically in a hospital or emergency department setting.
Not a fit: People without bloodstream infections, those whose infections are caused by organisms not covered by the test, or patients unable to provide blood samples are unlikely to benefit directly.
Why it matters
Potential benefit: If successful, patients could get identification and antibiotic-susceptibility results in hours instead of days, enabling faster, targeted treatment and less unnecessary use of broad-spectrum antibiotics.
How similar studies have performed: Some molecular diagnostics already speed up identification, but combining broad species detection with rapid single-cell antibiotic susceptibility testing is largely new and has limited patient-based validation so far.
