MRSA Agar Base (Powder)

MRSA Agar is used for the determination of methicillin-resistant and oxacillin-resistant Staphylococcus aureus. It was developed to detect the presence of the mecA gene (classic resistance) in S. aureus.\n\nMRSA Agar Base is composed of Mueller Hinton Agar and Sodium Chloride. Mueller Hinton Agar is made up of Beef Extract and Acid Hydrolysate of Casein, providing nitrogen, vitamins, carbon, and amino acids. Starch is added to absorb any toxic metabolites produced. Agar is the solidifying agent. The high concentration of Sodium Chloride enhances growth of S. aureus. Oxacillin is added to determine if the particular strain of S. aureus is oxacillin resistant.\n\nAppearance: Homogenous, free-flowing, beige\n\nPrepared Appearance: Prepared medium is hazy and yellow-beige.\n\nExpected Cultural Response:\n Without Oxacillin With Oxacillin\nS. aureus ATCC 25923 (susceptible) Growth No growth \nS. aureus ATCC 43300 (resistant) Growth No growth \n\n
