BBL™ CHROMagar™ Staph aureus is a selective medium for the isolation, enumeration and identification of Staphylococcus aureus from clinical and food sources. Confirmatory testing of typical isolates from clinical sources is not required.

BBL CHROMagar Staph aureus (prepared plated medium) has been validated by the AOAC™ Research Institute under the Performance Tested Methods^SM Program for the analysis of shell eggs, smoked salmon and cooked roast beef when using AOAC and ISO methods.^1,2 Confirmatory testing of mauve-colored colonies obtained from the food matrices mentioned above is required.

U.S. Patent No. 6,548,268

S. aureus is a well documented pathogen. It is responsible for infections ranging from superficial to systemic.^3,4 Due to the prevalence of this organism and its clinical implications, detection is of utmost importance.

Staphylococcal food poisoning caused by S. aureus is one of the most common types of foodborne illness worldwide. Its detection and enumeration help provide information about the potential health hazard of food, as well as being an indicator of poor hygiene.⁵ It is also recommended that this organism be used as an indicator of water quality.⁶

BBL CHROMagar Staph aureus is intended for the isolation, enumeration and identification of S. aureus based on the formation of mauve-colored colonies. The addition of chromogenic substrates to the medium facilitates the differentiation of S. aureus from other organisms.

An advantage BBL CHROMagar Staph aureus has over some traditional media, such as Baird-Parker Agar, is the ability to identify S. aureus in 24 h as opposed to 48 h.

See "Quality Control Procedures."

Quality control requirements must be performed in accordance with applicable local, state and/or federal regulations or accreditation requirements and your laboratory's standard Quality Control procedures. It is recommended that the clinical user refer to pertinent Clinical and Laboratory Standards Institute (formerly NCCLS) guidelines for appropriate Quality Control practices.

For in vitro Diagnostic Use.

If excessive moisture is observed, invert the bottom over an off-set lid and allow to air dry in order to prevent formation of a seal between the top and the bottom of the plate during incubation. Protect from light during drying. See Storage Instructions.

Pathogenic microorganisms, including hepatitis viruses and Human Immunodeficiency Virus, may be present in clinical specimens. "Standard Precautions"^7-10 and institutional guidelines should be followed in handling all items contaminated with blood and other body fluids.

After use, prepared plates, specimen or sample containers and other contaminated materials should be sterilized by autoclaving before discarding.
