On May 3, 2022, Yizhi Song's team from Suzhou Institute of Biomedical Engineering and Technology, Chinese Academy of Sciences, using the core product P300 confocal Raman spectrometer of HOOKE INSTRUMENTS,published titled "Single Cell Raman Spectroscopy Deuterium Isotope Probing for Rapid Antimicrobial Susceptibility Test of Elizabethkingia spp.” In Frontiers in Microbiology ,our team and Zhejiang University of Chinese Medicine jointly carried out the rapid drug sensitivity detection of Elizabethkingia bacteria based on heavy water labeling single cell Raman spectroscopy.



Nosocomial infection by multi-drug resistance Elizabethkingia spp. is an emerging concern with severe clinical consequences, particularly in immunocompromised individuals and infants. Efficient control of this infection requires quick and reliable methods to determine the appropriate drugs for treatment. In this study, a total of 31 Elizabethkingia spp., including two standard strains (ATCC 13253 and FMS-007) and 29 clinical isolates obtained from hospitals in China were subjected to single cell Raman spectroscopy analysis coupled with deuterium probing (single cell Raman-DIP). The results demonstrated that single cell Raman-DIP could determine antimicrobial susceptibility of Elizabethkingia spp. in 4 h, only one third of the time required by standard broth microdilution method. The method could be integrated into current clinical protocol for sepsis and halve the report time. The study also confirmed that minocycline and levofloxacin are the first-line antimicrobials for Elizabethkingia spp. infection.
