Descripción

Descripción general

Mueller Hinton Agar is specially designed for antibiotic susceptibility testing using the disc diffusion method (Kirby Bauer method). It has been recommended by the CLSI as the ideal medium for antibiotic susceptibility testing for the following reasons:

• It shows good reproducibility from batch to batch
• It is low in certain inhibitors like trimethoprim, sulfonamide and tetracycline
• It supports the growth of both fastidious and non-fastidious bacterial pathogens
• The starch in the media absorbs toxins thus preventing them from interfering with the antibiotics
• It is a loose agar and therefore facilitates better diffusion of antibiotics

Mueller Hinton Agar has been used:

• In culturing Escherichia coli ATCC™ 25922 strain for disc diffusion studies
• In disk diffusion assay of fusidic acid against Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa and Escherichia coli
• In agar diffusion assay of drug-loaded nano-hydroxyapatite formulations against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli

Aplicación

Mueller Hinton Agar is a solid medium originally designed for the isolation of pathogenic Neisseria species, now widely used for antibiotic susceptibility testing (including sulfonamides) of aerobic and facultatively anaerobic bacteria isolated from clinical specimens.

Nota de preparación

Suspend 38 g in 1 litre of distilled water, bring to the boil to dissolve the medium completely and sterilize by autoclaving at 121°C for 15 minutes.
