Opis

Opis ogólny

Mueller Hinton Broth 2 is recommended for testing the most encountered aerobic and facultative anaerobic bacteria found in food and clinical material for antimicrobial susceptibility testing. The medium shows good batch-to-batch reproducibility. It is low in sulfonamide, trimethoprim, and tetracycline inhibitors and yields satisfactory growth of most non-fastidious pathogens.Casein acid hydrolysate and beef extract provide amino acids and other nitrogenous substances, minerals, vitamins, and carbon to support the growth of microorganisms. To determine the MIC values with Enterococcus faecalis and sulfamethoxazole-trimethoprim, a special low content of thymine and thymidine in the amino acid sources is required. Starch neutralizes toxic substances that may be present in the medium and have an inhibitory effect on antibiotics and the growth of organisms. During autoclaving, a small amount of dextrose is hydrolyzed from starch, which is a source of energy. Calcium and magnesium salts are added to adjust the ion concentrations of the medium.

Zastosowanie

Mueller Hinton Broth 2 cation adjusted is intended for use in quantitative procedures for susceptibility testing of rapidly growing aerobic and facultatively anaerobic bacteria isolated from clinical specimens. It has been used for culturing Escherichia coli, Bacillus subtilis, Staphylococcus aureus and in the serial dilution of doxycycline.
