[Rapid bioluminescent antibiotic susceptibility assay]
Summary
This study introduces a rapid bioluminescent assay for antibiotic susceptibility testing. The new method provides accurate results in 5 hours, significantly faster than traditional techniques for pathogen analysis.
Area of Science:
- Microbiology
- Biotechnology
- Biochemistry
Background:
- Rapid antibiotic susceptibility testing is crucial for treating infections.
- Standard methods like disk diffusion and serial dilutions are time-consuming (18-36 hours).
Purpose of the Study:
- To develop and validate a rapid bioluminescent assay for determining pathogen antibiotic susceptibility.
Main Methods:
- The assay measures bioluminescence from adenosine-5'-triphosphate (ATP) and a firefly luciferase reagent.
- Bioluminescence intensity correlates with viable pathogen cell count.
- The method compares bioluminescence in pathogen suspensions with and without antibiotics after a 5-hour incubation.
Main Results:
- A coefficient of microbial growth inhibition was calculated.
- The bioluminescent assay demonstrated a satisfactory correlation (R2 > 88%) with standard methods.
- Results were obtained within 5 hours.
Conclusions:
- The bioluminescent assay offers a rapid and accurate alternative for antibiotic susceptibility testing.
- This method can aid in the rational chemotherapy of pyoinflammatory diseases and postoperative complications.
