Abstract

In the last two decades, microbiology laboratories have radically changed by the introduction of novel technologies, like Next-Generation Sequencing (NGS) and Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS). Nevertheless, emergence of antibiotic-resistant microorganisms represents a global threat of current medicine, being responsible for increasing mortality and health-care direct and indirect costs. In addition, the identification of antibiotic-resistant microorganisms, like OXA-48 carbapenemase-producing Enterobacteriaceae, has been changeling for clinical microbiology laboratories. Even the cost of NGS technology and MALDI-TOF MS equipment is relatively high, both technologies are increasingly used in diagnostic and research protocols. Therefore, the aim of this review is to present applications of these technologies used in clinical microbiology, especially in detection of antibiotic resistance and its surveillance, and to propose a combinatory approach of MALDI-TOF MS and NGS for the investigation of microbial associated infections.
