MUELLER-HINTON BROTH
Code：CM0405
Directions
Place 21.0g in 1 litre of distilled water mix to dissolve completly. Sterilize by autoclaving at 121°C for 15 minutes. Chill and adjust cation levels if necessary1.
Description
Oxoid Mueller-Hinton Broth has been produced in parallel with Oxoid Mueller-Hinton Agar CM0337. Where studies on antibiotic susceptibilities are being made both in broth and agar, it will be found to be of particular value to have media of identical nutrient formulation.
Mueller-Hinton Broth is recommended for broth dilution MIC studies1.
Oxoid Mueller-Hinton Broth will require supplementation with the divalent cations Mg++ and Ca++ after sterilisation2. The CLSI recommend the following cation levels Ca++, 20-25mg/litre; Mg++, 10-12.5mg/litre.
Lysed horse blood or thymidine phosphorylase may be added to the broth to improve the MIC endpoints of sulphonamides and trimethoprim3.
Mueller-Hinton Broth containing horse serum and agar added to create a semi-solid agar medium was used in microtitre plates in an agar dilution method for determining the MIC for Helicobacter pylori of a number of antibiotics. The method does not require prolonged incubation in carbon dioxide-enriched air and results are available in 48 hours compared to 3-4 days for agar diffusion testing on solid medium4.
For further details of antimicrobial susceptibility testing see relevant section.
