The assay relies on mass spectrometry to quantify the number of S. aureus organisms in a large number of samples in just a few hours.
The prototype mass spectrometry-based technique can detect low concentrations of bacteria, enabling physicians to diagnose staph infections without the need for a significant culture period.
Georgia Tech School of Chemistry and Biochemistry associate professor Facundo Fernández said their method for detecting staph infections using mass spectrometry will be important in a range of situations, where a large number of people need to be tested quickly.
The research was partially funded by 3M and the CDC/Georgia Tech seed award program.
CDC research chemist Pierce said the simplicity of sample preparation, the low cost of required reagents and the increased availability of mass spectrometers in clinical laboratories make this new method a cost-effective way to rapidly and effectively detect staph infections.
