Research progress in bacterial resistance to antibiotics analyzed based on MALDI-TOF MS mass peak / 中华微生物学和免疫学杂志

ABSTRACT

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has become a widely used method in the field of microbial identification. Its obvious advantages including rapidity, great accuracy and high throughput attract many researchers to investigate its potential for usage in other microbiological fields. Currently, several studies have reported MALDI-TOF MS-based analysis of bacterial resistance to antibiotics, which can identify the specific heterogeneous spectrum peaks related to drug resistance through simple visual analysis of the spectrum or more complex analysis of the entire spectrum using informatics methods and statistical approaches. Therefore, MALDI-TOF MS has become a potential tool for detecting antibiotic resistance in bacteria. This review mainly summarized the progress in MALDI-TOF MS-based analysis of bacterial resistance to antibiotics.
