broth microdilution

Broth microdilution is a laboratory method used to determine the effectiveness of antibiotics against specific bacteria. In this process, various concentrations of an antibiotic are mixed with a bacterial culture in small tubes or wells. By observing the growth of bacteria at different concentrations, scientists can identify the minimum amount of the antibiotic needed to inhibit bacterial growth. This method helps in understanding how to treat infections more effectively and in the development of new antibiotics, ensuring that the right dosage is used to combat specific bacterial infections.
