Abstract

A method for detect bacterial drug resistance by single cell analysis comprises mixing a certain amount of bacterial sample and a certain amount of antibiotic diluent on a slide, covering that slide with a cover glass and sealing with a sealant on four side to form a plate-type microbiochemical reaction system in which the bacterial and antibiotic diluent react biochemically. Bacteria were observed and located by phase contrast microscope and Raman spectra were obtained by laser scanning. Bacterial drug resistance could be obtained by analysis. The invention also provides a device for realizing the method, and the device comprising a plate-type micro-biochemical reaction system, a phase contrast microscope, a high-power optical microscope, a Raman spectrum excitation system and a Raman spectrum collection system. Bacteria were observed by phase contrast microscope and high power optical microscope, and then Raman spectra were obtained by Raman spectrum excitation system and Raman spectrum collection system to detect bacterial drug resistance.

Description

technical field [0001] The invention relates to the field of physics, in particular to optical detection technology, in particular to a method and device for detecting bacterial drug resistance through single-cell analysis. Background technique [0002] According to a comprehensive analysis of various data by relevant professors from Zhejiang University School of Medicine, it is found that the total annual consumption of antibiotics in my country is about 150,000 to 200,000 tons, accounting for about 50% of the world's total usage. At the same time, due to factors such as dense population, distribution of pharmaceutical industry, agriculture, and breeding industry, the antibiotic use and discharge density in eastern China's watersheds is more than 6 times higher than that in western watersheds. Massive and often unnecessary antibiotic use means that an increasing number of pathogens are drug-insensitive, and previously treatable infections can become life-threatening. [00...
