Raman spectroscopy can be used to identify bacteria and evaluate drug resistance, researchers reported at the American College of Surgeons 97th Annual Clinical Congress. The method uses near-infrared light to detect the molecular spectral pattern of the bacteria in blood, urine or sputum samples. "Raman spectroscopy can detect methicillin-resistant Staphylococcus aureus with 96% sensitivity, and vancomycin susceptibility in an S aureus sample with 100% sensitivity," said lead author Dr. Amy Spencer.
