Staphylococcus aureus is a major pathogenic bacterium found in clinical field and in food industry. Nosocomial infections due to Staphylococcus aureus create an increasing number of problems, so it is becoming more and more important to detect Staphylococcus aureus and in particular, methicillin resistant Staphylococcus aureus (MRSA). A conventional media for the detection of Staphylococcus aureus is Mannitol Salt Agar (called Chapman Agar in Europe). This media based on hypersalinity and fermentation of mannitol has an excessive rate of false positives and of false negatives. CHROMagar Staph. aureus is a selective chromogenic medium of high specificity and high sensitivity. Another conventional media to detect Staphylococcus aureus is Blood Agar which requires the tedious and costly examination with immunological tests of 5-10 colonies per suspected sample. On the other hand CHROMagar Staph aureus, in eliminating most false positives, is more convenient and more powerful than conventional methods. With CHROMagar Staph aureus, testing a single colony with typical color for further identification will generally be sufficient for high probability detection of Staphylococcus aureus. In supplementing CHROMagar Staph. aureus with an appropriate antibiotic, for instance tobramycin or methicillin, one can obtain information related to some methicillin resistant Staphylococcus aureus strains.
