Company. The CLSI recommend the following cation levels Ca++, 20-25mg/litre; Mg++, 10-12.5mg/litre. Mueller Hinton Broth, not cation-adjusted, is a dehydrated culture medium that is not supplemented with calcium or magnesium ions. [17–19]. Mueller-Hinton Broth will require supplementation with the divalent cations Mg++ and Ca++ after sterilization 2. All models were filled with 1,000 ml of cation-adjusted Mueller-Hinton II broth (MHB) (Becton, Dickinson and Company, Sparks, MD) supplemented with polysorbate 80 (Tween 80) to achieve a final concentration of 0.002% of the latter, as recommended for telavancin MIC testing in broth. Omission of divalent ions could therefore greatly affect your MIC values. One part of the answer is that calcium is believed to stabilise cell walls. For antimicrobial susceptibility testing of microorganisms by broth dilution methods. Based on the fact that these cations are not volatile compounds, and heating by autoclave will help to dissolve the cations in the broth, can I add the supplemental cations before autoclave?

The medium is designed to give a low thymine and thymidine content and also the calcium and magnesium ion concentration is adjusted as recommended by CLSI (2). Cation-adjusted Mueller Hinton Broth is the medium usually used for dilution antimicrobial susceptibility tests. Isolates were cultured in cation-adjusted Mueller-Hinton broth (CAMHB), CAMHB plus 2% (v/v) lysed horse blood, Brain-Heart-Infusion (BHI) (Becton Dickinson, Heidelberg, Germany) and Caso broth (Sigma-Aldrich, Seelze, Germany), which are frequently used media for the cultivation of Bordetella spp. However as stated in all CLSI documents, I should prepared it to be "cation-adjusted Mueller Hinton broth (CAMHB)" for fastidious bacteria. BD Difco™ BBL™ Dehydrated Culture Media: Mueller Hinton II Broth (Cation-Adjusted) is part of a large selection of dehydrated media. It is formulated to have a low thymine and thymidine content. Why is cation adjusted Mueller Hinton Broth used? In a previous study, addition of 100 mg/L of magnesium and calcium ions to commercial media deficient in these cations increased ciprofloxacin MICs four-fold.24 The concentration of magnesium ions in this study was approximately half that used in the study by Blaser & Luthy,24 therefore the half dilution difference is consistent with earlier observations and is presumably a result of increased concentrations of magnesium ions. 1 However, this medium is not satisfactory for fastidious organisms such as S. pneumoniae. What is the best optical density equivalent to 0.5 MacFarland standard for Pseudomonas in MIC determination? This medium is supplemented with calcium and magnesium salts to produce correct MICs with aminoglycosides and Pseudomonas aeruginosa. Mueller Hinton Broth, not cation-adjusted, is a dehydrated culture medium that is not supplemented with calcium or magnesium ions. Abstract. Nowadays, it is more commonly used for the routine susceptibility testing of non-fastidious microorganism by the Kirby-Bauer disk diffusion technique. Mueller-Hinton Broth will require supplementation with the divalent cations Mg++ and Ca++ after sterilization 2.

Email * Catalog Number * CofA. A multilaboratory study was undertaken to reassess the amount of calcium and magnesium that should be added to Mueller-Hinton broth when testing Pseudomonas aeruginosa against amikacin, gentamicin, isepamicin, netilmicin, and tobramycin. The antimicrobial agents that differed were those most affected by varying concentrations of cations in the medium, namely quinolones, aminoglycosides and tetracycline.7–11 The calcium and magnesium ion levels in the CAMHB were equivalent to those recommended in NCCLS guidelines (20–25 and 10–12.5 mg/L, respectively). For nearly a century, University of Iowa researchers have studied the science and technology of water management.
