☰ Summary :
In liquid medium, bacterial growth is visualized by a bacterial disorder.
MIC (minimum inhibitory concentration) : the lowest concentration of antibiotic inhibiting the visible growth of a given strain.
Mueller-Hinton (MH) broth, adjusted for divalent cations, is used in the liquid dilution method (micro-dilution) for non-demanding bacteria.
MH-F broth, MH broth supplemented with 5% lysed horse blood and 20 mg / L β-NAD, is used for Streptococcus spp., Including Streptococcus pneumoniae, Haemophilus spp., Moraxella catarrhalis, Listeria monocytogenes, Campylobacter spp. ., Pasteurella sp., Corynebacterium sp. and other slow growing bacteria.
MIC in liquid medium
Conclusion : The higher the concentration required, the higher the MIC and the less sensitive the germ.
