Comparison of clinical methods for the phenotypic detection of Methicillin resistant Staphylococcus aureus: Disc diffusion methods with BrillianceTM MRSA agar

Abstract

This study was based on the comparison of revised guidelines of Clinical and Laboratory Standardshowing sensitivity and specificity of 96.8% and 100% respectively. The cefoxitin disc diffusion method appears to be a good option for the identification of MRSA. Brilliance TM MRSA agar when used for the detection of MRSA, showed sensitivity and specificity of 98.4% and 100% respectively. In conclusion the efficiency of FOX is very high and FOX disc diffusion method is the most efficient method for the identification of MRSA phenotypically and could be a second choice for the detection of MRSA.

Phenotypic Detection of Β-Lactam Antibiotics, Methicillin and Inducible Clindamycin Resistance Among Bacterial Isolates in Patients with Otitis Externa

“…Methicillin-resistant S. aureus (MRSA) species are known as the main cause for serious (nosocomial infection and/or acquired community) infections; they are usually resistant to many other commonly used antibiotics (4,8,9).…”
