Developing a standardized bacterial inoculum of about 5x105 CFU/mL. three. Diluting the antibiotic in the number of tubes containing broth and adding the bacterial inoculum. 4. Incubating the tubes right away and acquiring the bottom antibiotic concentration tube that displays no obvious advancement, which can be the MIC. The MBC can even check here be based on culturing samples from crystal clear tubes.
Turbidity steps light-weight absorption by a bacterial suspension to estimate mobile concentration. Immediate microscopic rely straight counts cells in the regarded volume below a microscope but can't distinguish Are living from dead cells.
