摘要：

The spread of multidrug-resistant (MDR)Klebsiella pneumoniaein the nosocomial setting represents a big challenge to infection control teams. We have recently developed a simple spectroscopic-based method with excellent accuracy, turnaround time and cost-effectiveness (Rodrigues et al. mSystems 2020) for bacterial typing. Here, we applied our method in a real clinical context to support early identification of an outbreak involving KPC-3-producingK. pneumoniaeST147 isolates. Our results further support that attenuated total reflectance Fourier transform infrared (FT-IR) spectroscopy can provide enough information to support early and adequate infection control measures and therapeutic choices in the context of nosocomial outbreaks and hospital surveillance.
