Lab testing to understand antibiotic resistance in dangerous Gram-negative bacteria

Core 2 Mechanistic Assay Core

NIH-funded research University of Florida · NIH-11164494

This project develops laboratory tests to reveal how two hard-to-treat bacteria block or remove antibiotics, with the goal of helping people who have drug-resistant infections.

What this research studies

Researchers will run and refine mechanistic assays that measure outer membrane permeability, β-lactamase activity, intracellular drug accumulation, and washout kinetics for carbapenem-resistant Acinetobacter baumannii and Klebsiella pneumoniae. The Mechanistic Assay Core will provide standardized, cutting-edge tests that support multiple linked projects focused on antibiotic combinations. Data from these assays will be used to design rational combination dosing regimens of existing and new antibiotics. The core integrates results across projects to translate lab findings toward clinically relevant treatment strategies for resistant Gram-negative infections.

Who could benefit from this research

Good fit: People with confirmed or suspected infections caused by carbapenem-resistant Acinetobacter baumannii or carbapenem-resistant Klebsiella pneumoniae would be the clinical group most likely to benefit from resulting treatments.

Not a fit: Patients with infections caused by non–Gram-negative organisms (for example viral or fungal infections) or with bacteria that are already drug-susceptible are unlikely to benefit directly from this core's findings.

Why it matters

Potential benefit: If successful, this work could lead to better antibiotic combinations and dosing plans that improve outcomes for people with multidrug-resistant Acinetobacter or Klebsiella infections.

How similar studies have performed: This core builds on previously developed mechanistic assay platforms (including prior R01-funded work) and extends established methods to new combination-therapy questions.
