Discover Mueller Hinton II Agar, an essential culture medium for antimicrobial susceptibility testing, designed to ensure reliable and accurate results. This product complies with the international standards established by the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST), making it the ideal choice for microbiology laboratories and research institutions.

Features of Mueller Hinton II Agar

• Format: Pack of 20 90 mm plates


• Application: Antimicrobial susceptibility testing using the disk diffusion technique (Kirby-Bauer method)


• Microorganisms: Recommended for rapidly growing aerobic organisms

Medium Composition

The typical formula of Mueller Hinton II Agar is as follows:

• Beef Extract: 2.0 g/l


• Acid Hydrolysate of Casein: 17.5 g/l


• Starch: 1.5 g/l


• Agar: 17.0 g/l


• Final pH: 7.3 ± 0.2 at 25°C

Principle of the Test Method

Mueller Hinton II Agar is formulated to provide an optimal environment for microorganism growth. Here is how it works:

• Nutrient Source: The acid hydrolysate of casein and beef extract provide amino acids, nitrogen, carbon, vitamins, and essential minerals.


• Protection from Toxins: Starch acts as a protective colloidal agent, neutralizing toxic molecules in the medium.


• Energy for Growth: During sterilization, starch hydrolyzes, releasing glucose, an energy source for microorganisms.


• Antimicrobial Diffusion: The Kirby-Bauer method uses disks impregnated with antimicrobial substances, which diffuse through the agar, creating an inhibition zone around the disk.

Advantages of Using Mueller Hinton II Agar

Using Mueller Hinton II Agar offers numerous advantages, including:

• Reliability: Consistent and reproducible results for antimicrobial susceptibility assessment.


• Standardization: Complies with CLSI and EUCAST standards, ensuring test accuracy.


• Ease of Use: Ready to use and easy to handle, ideal for laboratories of any size.

Conclusion

Choose Mueller Hinton II Agar for your antimicrobial susceptibility tests and ensure precise and reliable results. This culture medium is a fundamental element for every microbiology laboratory and represents an investment in the quality and reliability of your analyses.
