DOI: 0.1007/s10096-020-03956-y0934-9723http://hdl.handle.net/10400.11/7369The spread of multidrug-resistant (MDR) Klebsiella pneumoniae in 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-producing K. pneumoniae ST147 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.engBacterial typingNosocomial infectionCarbapenemasesKPC-3Capsule typeCapsular polysaccharidesjournal article10.1007/s10096-020-03956-y
