Abstract:

The application of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) has brought a revolutionary change for microbial identification program in clinical microbiological laboratories,for its fast,high-throughput,accuracy and cost-effectiveness. Furthermore,MALDI-TOF MS provides a new way for drug resistance determination. It is time-consuming for commonly-used methods of routine drug resistance determination,such as Kirby-Bauer,dilution and E-test. These methods can not meet the clinical demand for quick selection of sensitive drugs. So,the application of MALDI-TOF MS for the determination of drug resistance has research value and prospect. Some experiments and clinical application of MALDI-TOF MS for determining drug resistance have been reported. This review introduces the types of pathogens,determination methods and the efficiency of MALDI-TOF MS for determining drug resistance in recent years.

Key words: Matrix-assisted laser desorption ionization time of flight mass spectrometry, Bacteria, Drug resistance
