The principle of microbial susceptibility culture monitor

The principle of the microbial drug susceptibility culture monitor is to use microbial culture technology to culture and identify microorganisms in patient samples, and at the same time conduct an antibiotic sensitivity test (i.e. drug susceptibility test) to determine the resistance of a certain microorganism to a certain antibiotic. sensitivity and its optimal concentration. The specific principles are as follows:
1. Microbial culture: Microorganisms in patient samples are grown on culture media to form bacterial colonies.
2. Drug sensitivity test: Add a series of antibiotics at different concentrations to the culture medium to observe the effects of different antibiotics on microbial growth.
3. Drug minimum inhibitory concentration (MIC) determination: Determine the minimum inhibitory concentration of microorganisms against a certain antibiotic, that is, the lowest antibiotic concentration at which the growth of microorganisms is inhibited.
4. Automatic analysis: The microbial drug susceptibility culture monitor performs automatic analysis, evaluates the sensitivity of microorganisms to antibiotics, and generates a drug susceptibility report.
Through drug susceptibility testing, medical staff can select the most effective drugs and determine the best medication regimen when using antibiotics in clinical settings, thereby improving the therapeutic effect and reducing the rate of antibiotic abuse and the occurrence of drug resistance.
