- MICs Minimum Inhibitory Concentrations
- bacterial suspensions are prepared from an isolated colony taken from Mueller-Hinton agar taken up in 5 mL of Mueller-Hinton broth. After 24 hours of growth, the bacterial suspensions are diluted in sterile distilled water to obtain an inoculum of 10 5 - 10 6 CFU / mL. The purity of the bacterial suspensions is controlled by agar isolation and Gram stain.
- the MICs are determined using an ELISA plate reader (at 540 nm, Multiskan EX, Thermo Electron Corporation, France) as the concentrations of active substance for the absorbance is comparable to that of the negative control (culture medium alone or with the drug, without the inoculum). The results are the average of 4 independent experiments.
